This application claims priority to the following application: US filed on February 7, 2017, entitled "Narrow Width Adapters And Connectors with Modular Latching Arm" Provisional Application No. 62,457,150; U.S. Provisional Application No. 62,457,150, filed August 23, 2017, entitled "Narrow Width Adapters And Connectors with Modular Latching Arm" 62/546,920; U.S. Provisional Application No. 62/2017, entitled "Narrow Width Adapters And Connectors with Modular Latching Arm," filed January 20, 2017 No. 452,147; U.S. Provisional Application Serial No. 62/430,560, filed December 6, 2016, entitled "Narrow Width Adapters And Connectors with Spring Loaded Remote Release" No.; and the title of the application on December 5, 2016 entitled "Narrow Width Adapters and Connectors with Spring Loaded Distal Releases and Connectors (Narrow Width Adapters And Connectors with Spring Loaded Remote Release), each of which is hereby incorporated by reference in its entirety.

The present disclosure relates generally to connectors having distal releases, and more particularly to narrow width adapters and connectors, such as Lucent Connector (LC) duplex adapters and narrow width multi-fiber connectors.

The popularity of the Internet has enabled unprecedented growth of communication networks. Consumer demands for services and increasing competition have forced network providers to continually seek ways to improve service quality while reducing costs.

Some workarounds include configuring HDI panels. HDI panels can be designed to ensure the ever-increasing interconnect volume required to support the rapidly growing network into a compact form factor, thereby increasing service quality and reducing costs such as floor space and support surcharges. However, the configuration of HDI panels has not yet been fully realized.

In communication networks, such as in data centers and switching networks, it is possible to compact multiple interconnects between mating connectors to form high-density panels. Panel and connector manufacturers can optimize these high densities by reducing the size of the connectors and/or the spacing between adjacent connectors on the panel. While both approaches are effective for increasing panel connector density, reducing connector size and/or pitch also increases support costs and reduces service quality.

In a high density panel configuration, adjacent connector and cable assemblies can block access to the independent release mechanism. The physical obstruction will impair an operator's ability to reduce stress on the cables and connectors force. These stresses are applied, for example, when a user enters a dense set of connectors and uses his/her thumb and forefinger to push the surrounding fibers and connectors away in order to access a separate connector release mechanism. Overstressing these cables and connectors can create potential defects that compromise the integrity and/or reliability of these terminations and can wreak havoc on network performance.

Although an operator can attempt to use tools such as a screwdriver to access a dense set of connectors and actuate a release mechanism, the adjacent cables and connectors block the operator's view, making it difficult to operate without pushing the adjacent connectors apart. Guide the tool to the release mechanism adjacent to the cable. Furthermore, even when the operator has a clear line of sight, guiding the tool to the release mechanism is a time consuming process. Therefore, using a tool is not effective for reducing support time and increasing service quality.

Small Form Factor Pluggable Transceivers (SFPs) known as Ethernet switches and/or patch hubs are currently used in rack-mounted copper-to-fiber media converters in telecommunications infrastructure. ). Due to the limited space available for these infrastructure Ethernet and fiber optic connections, these devices are rapidly evolving to increase connection density. While fiber optic connectors have gotten smaller over the years, they have not been designed to be smaller than required to plug into a common size and readily available SFP. However, as transceiver technology evolves, smaller SFPs will be used to create higher density switching and/or patch hub devices. Therefore, there is a need for fiber optic connectors that can meet future growth needs of smaller SFPs.

This disclosure is not limited to the particular systems, devices and methods described, as these may vary. The terms used in the description are for the purpose of describing the specific forms or embodiments only, and are not intended to limit the scope.

As used in this document, the singular forms "a", "the" and "the" include plural designations unless the context clearly indicates otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. Nothing in this disclosure is to be construed as an admission that the embodiments described in this disclosure are not entitled to antedate this disclosure by virtue of prior invention. The term "comprising" is used in this document to mean "including, but not limited to".

For the purposes of this application, the following terms shall have the meanings described below.

As used herein, a connector refers to a device and/or components thereof that connect a first module or cable to a second module or cable. The connector can be assembled for optical fiber transmission or electrical signal transmission. The connector can be any suitable type currently known or developed in the future, such as a ferrule connector (Ferrule Connector, FC), a fiber distributed data interface (Fiber Distributed Data Interface, FDDI) connector, an LC connector , a mechanical transfer (Mechanical Transfer, MT) connector, a square connector (Square Connector, SC) connector, an SC duplex connector, or a straight tip (Straight Tip, ST) connector. The connector may be generally bounded by a connector housing body. In some embodiments, the housing body can have any or all of the components described herein.

A "fiber optic cable" or a "fiber optic cable" means a A cable that conducts one of the optical signals in a plurality of light beams or a plurality of optical fibers. The optical fibers may be constructed of any suitable transparent material, including glass, fiberglass, and plastic. The cable may include a jacket or coating material surrounding one of the optical fibers. Additionally, the cable may be connected to a connector on one or both ends of the cable.

Various embodiments described herein provide a remote release mechanism that allows a user to remove cable assembly connectors that are closely spaced apart on a high density panel without damaging or disabling surrounding connectors. Accidental separation, uninterrupted transmission through surrounding connectors, etc. Various embodiments also provide narrow pitch LC duplex connectors and narrow width multi-fiber connectors for use with, for example, future narrow pitch LC SFPs and future narrow width SFPs. The distal release mechanism allows the narrow pitch LC duplex connectors and narrow width multi-fiber connectors to be used in dense narrow pitch LC SFP and narrow width multi-fiber SFP arrays.

FIG. 1A shows a perspective view of a conventional standard 6.25mm pitch LC connector SFP100. The SFP 100 is assembled to accommodate a duplex connector, and provides two sockets 102, each socket is used to accommodate an LC connector. The pitch 104 is defined as the interaxial distance between the central longitudinal axes of each of the two sockets 102 . FIG. 1B shows a perspective view of a conventional standard 6.25 mm pitch LC adapter 106 . The adapter 106 is also configured to accommodate a duplex connector, and provides two sockets 108, each socket is used to accommodate an LC connector. FIG. 1C is a top view of the adapter 106 of FIG. 1B . The spacing between the adapters 106 is defined similarly to the spacing between the SFPs 100 as the interaxial distance between the central longitudinal axes of each of the two receptacles 108, as shown in the front view of the adapter 106. Figure 1D.

FIG. 2A shows a conventional LC duplex connector 200 that can be used with the conventional SFP 100 and the conventional adapter 106 . The LC duplex connector 200 includes two conventional LC connectors 202 . FIG. 2B shows another conventional LC duplex connector 204 having a distal release tab 206 and including two conventional LC connectors 208 . As shown, the distal release tab includes two pins 210 , and each pin is configured to be coupled with an extension member 212 of each LC connector 208 . 2C and 2D show top and side views, respectively, of the conventional LC connector 208 with a width of 5.6 mm, and further show the extension member 212 .

Various embodiments disclosed herein are configured for use with a future SFP, such as the narrow pitch LC SFP 300 shown in FIG. 3 with a pitch smaller than the conventional 6.25 mm and 5.25 mm pitches. As described further below, various embodiments use LC-type fiber optic connectors in duplex configurations (with transmit and receive fibers), but with a connector-to-axial distance that is smaller than conventional 6.25mm and 5.25mm pitches.

According to another aspect, an embodiment of a narrow pitch duplex LC adapter is disclosed. 4A to 4C show an embodiment of a narrow pitch adapter 400 . According to aspects disclosed herein, the narrow pitch adapter 400 has receptacles 402 on opposite ends thereof, and the receptacles 402 are configured to mate with two narrow pitch LC duplex connectors. FIG. 4B shows a top view of the adapter 400 . FIG. 4C shows a front view, which further shows that the adapter 400 has a spacing of 4.8 mm. The adapter 400 is configured to accommodate a duplex LC connector, and a pitch of the adapter corresponds to the LC connector on the LC duplex connector. the distance between the axes. Although the adapter 400 has a pitch of 4.8 mm, various embodiments of the narrow pitch adapters disclosed herein can have a different pitch that is less than the pitch of conventional adapters, such as less than 6.25 mm and less than about 5.25 mm. In some embodiments, the spacing may be equal to or less than about 4.8 mm.

In addition to the need for narrow connectors, there is also a need to remotely unlock narrow connectors used in dense narrow SFP arrays. This is because it is nearly impossible for a finger to access the connector without disrupting service to adjacent fibers. While there are currently designs for unlocking fiber optic connectors remotely, as shown for example in Figure 2B, they have proven difficult to function as desired when inserted into the molded configuration typical of all SFPs. The molded SFP is free from sharp edges and internal flash (burrs) that would interfere with the normal flexing action of the plastic latches of the fiber optic connectors. Interference between metal edges and burrs prevents the fiber optic connector's plastic latch from being fully actuated, particularly when the latch is actuated distally by a pull tab protruding a distance behind the connector to prevent fingers from interfering with adjacent fibers. Join or separate easily.

In order to make the latching/unlocking of the connectors relative to the SFP more reliable, various embodiments disclosed herein, such as the remote latching as shown and described below with respect to FIGS. 5, 7, 8 and 12 The component (pull tab) adds a spring force to ensure that the connector latches can return to the undisplaced position and thus become fully engaged within the recess of the SFP.

FIG. 5 shows an embodiment of a narrow pitch connector 500 according to aspects disclosed herein. The narrow pitch connector 500 includes two LC connectors 502 , one of which is a duplex LC connector. Each LC connector 502 includes a set of ferrules 503 and an extension member or latch arm 504. The connector 500 has a pitch of 4.8 mm, and the pitch is defined as the interaxial distance between the central axes of the LC connectors 502 . In other embodiments, the connector spacing may be smaller than conventional connector spacing, such as less than 6.25 mm and less than about 5.25 mm. In some embodiments, the spacing may be equal to or less than about 4.8 mm.

The connector 500 further includes a housing 506 having a bottom housing 508 and a top housing 510 . The bottom housing 508 includes side walls 512 . In various embodiments, the housing 506 of the connector 500 may be a convertible housing. The side walls 512 can be configured to be openable to open the housing 506 to change the polarity of the connector 500, for example. The sidewalls 512 can protrude toward the rear of the connector 500 , as shown in FIG. 5 . An advantage of having the sidewalls 512 raised toward the rear of the connector 500 is that it is easier to access. In other embodiments, the sidewalls 512 can be raised at another position.

The connector 500 further includes a pull tab 514 having a distal end 516 and a proximal end 518 . The pull tab 514 further includes a spring 520 configured to provide a force causing the connector latch arm 504 to return to the undisplaced position and thus become fully engaged within the recess of the SFP. The distal end 516 of the pull tab 514 can be pulled to remotely release the connector 500 by an SFP or adapter. The proximal end 518 of the pull tab 514 has a unique shape to engage the unique contour of the latch arm 504 of the narrow pitch LC connector 500 . The proximal end 518 engages the two latch arms 504 of the duplex LC connector 500 . That is, the proximal end 518 includes a single pin configured to engage the latch arms of the two connectors 502 . The proximal end 518 of the pull tab 514 has a plurality of Pins 522 extend outwardly and are configured to be placed directly over and slide along the semicircular surface of the latch arm 504 of the duplex LC connector 502 . The horizontal and rearward path direction of the pins 522 curves the semicircular profile of the connector latch arms 504 downward. Because the pins 522 are not housed in the angled slots of the connector latch arms 504, the pull tab 514 can also be pushed down at a position directly behind the LC connectors 502 rather than by At one of the distal ends behind the connectors, for example, the distal end 516 pulls the sheet to move backward. The action of pushing down an integral lever or latch arm 504 of the connectors unlocks the connectors 500 . In some cases, horizontal movement of the pull tab 514 may not be required. Therefore, the connector latch arms 504 can be pushed down without horizontal movement of one of the pull tabs 514 .

6A and 6B show a top view and a side view of the LC connector 502 of the narrow pitch connector 500, respectively. FIG. 6A further shows that the LC connector 502 has a width of 4.6mm. FIG. 6B shows the semicircular outline of the latch arms 504 .

FIG. 7 shows a partially exploded view of the narrow pitch connector 500 of FIG. 5 . The top case 510 is separate from the bottom case 508 . The pull tab 514 is coupled to the top case 510 and is configured to slide longitudinally along the length of the connector. The top case 510 also includes a stopper 524 , and the stopper 524 is configured to accommodate the pull tab 514 .

FIG. 8 shows a further exploded view of the narrow pitch connector 500 . In detail, the pull tab 514 is shown separated from the top case 510, and the spring 520 is taken out of the pull tab. The pull tab 514 includes a longitudinal recess 526 configured to receive the spring 520, and configured to hold the spring at least one stopper 528 . The top case 510 also includes a recess 530 configured to receive at least a portion of the pull tab 514 , such as the spring 520 and the proximal end 518 . In various embodiments, the pull tab can be distally coupled to the connector through the top case.

Figure 9 shows a perspective view of a conventional standard MPO SFP900. The SFP 900 is configured to receive a standard MPO connector and provides a receptacle 902 for receiving an MPO connector of a conventional width, as shown, for example, in FIGS. 10A-10C .

FIG. 10A shows a perspective view of a conventional MPO connector 1000 . As shown in FIG. 10B, the conventional MPO connector 1000 has a width of 12.4 mm. FIG. 10C shows a front view of the MPO connector 1000 .

FIG. 11 shows an embodiment of a future narrow width multi-fiber SFP 1100 according to one aspect of the present disclosure. Various embodiments disclosed herein are configured for use with the narrow width multi-fiber SFP 1100 having a width that is less than the width of conventional MPO connectors, ie less than about 12.4 mm. The narrow width multi-fiber SFP has a receptacle 1102 configured to receive a narrow width multi-fiber connector, such as a narrow width connector with an MT ferrule.

FIG. 12A shows an embodiment of a narrow width connector 1200 in accordance with aspects disclosed herein. The narrow width connector 1200 is a multi-fiber connector including a multi-fiber MT/MPO ferrule 1202 . The connector 1200 includes two extension members or latch arms 1204 . In other embodiments, the connector may include at least one latch arm. The connector 1200 has a width of 9.6 mm, as shown in the top view of the connector 1200 in FIG. 12B Show. In other embodiments, the connector width may be smaller than that of the conventional multi-fiber connector, for example, smaller than 12.4 mm of the conventional MPO connector shown in FIG. 10B . In certain embodiments, the width may be equal to or less than about 9.6 mm.

The connector 1200 further includes a housing 1206 having a bottom housing 1208 and a top housing 1210 . The bottom housing 1208 includes side walls 1212 . In various embodiments, the housing 1206 of the connector 1200 may be a switchable housing. The side walls 1212 can be configured to be openable to open the housing 1206 to change the polarity of the connector 1200, for example. The sidewalls 1212 can protrude toward the rear of the connector 1200 . An advantage of having the side walls 1212 raised toward the rear of the connector 1200 is that it is easier to access. The sidewalls 1212 can also be raised at another position.

The connector 1200 further includes a pull tab 1214 having a distal end 1216 and a proximal end 1218 . The pull tab 1214 further includes a spring 1220 configured to provide a force causing the connector latch arm 1204 to return to an undisplaced position and thus become fully engaged within the recess of the SFP. The distal end 1216 of the pull tab 1214 can be pulled to remotely release the connector 1200 by an SFP or adapter. The proximal end 1218 of the pull tab 1214 has a unique shape to engage with the unique contour of the latch arm 1204 of the narrow pitch multi-fiber connector 1200 . The proximal end 1218 engages two latch arms 1204 of the multi-fiber connector 1200 . That is, the proximal end 1218 includes a single prong configured to engage the latch arms 1204 . The proximal end 1218 of the pull tab 1214 has a plurality of outwardly protruding pins 1222, and these pins 1222 are assembled to be placed directly on the semicircular surface of the latch arms 1204 over and slide along it. The horizontal and rearward path direction of the pins 1222 curves the semi-circular profile of the connector latch arms 1204 downward. Because the pins 1222 are not housed in the angled slots of the connector latch arms 1204, the pull tab 1214 can also be pushed down at a position directly behind the latch arms 1204 rather than by At a distal end behind the connector, for example, the distal end 1216 pulls the tab to move backward. The action of pushing down an integral lever or latch arm 1204 of the connectors unlocks the connectors 1200 . In some cases, horizontal movement of the pull tab 1214 may not be required. Therefore, the connector latch arms 1204 can be pushed down without horizontal movement of one of the pull tabs 1214 .

12B and 12C show a top view and a front view of the narrow width multi-fiber connector 1200, respectively. FIG. 12B further shows that the connector 1200 has a width of 9.6 mm.

In the various embodiments described above, the narrow width connectors have a plurality of latch arms configured to engage a fixed or non-movable recess within a narrow width SFP or a narrow width adapter. In these embodiments, the pull tab of the connector moves the flexible latch arm of the connector to disengage the latch arm from the recess of the SFP or the adapter. For example, the latch arms bend downward when the pull tab is pulled back to separate the connector from the SFP or the adapter.

In other embodiments, the distal latch release tab can be configured to engage a latch or a hook within the adapter or the SFP, as further described below with respect to, for example, FIGS. 13A, 13B, 14, and 15. coupling. In these embodiments, the flexible latch arm of the connector is moved into the SFP or the mating The main cavity of the device, and when the tab is in a normal position pushed forward by a spring, the latch of the SFP or the adapter engages a recess of the connector. The pull tab can be configured to have a beveled area so that when the pull tab is pulled back, the latch of the SFP or the adapter is lifted by the pull back tab, whereby the latch of the SFP or the adapter is in contact with the The connector separates.

Figure 13A shows a narrow pitch multi-fiber connector 1300 inserted into a narrow pitch SFP 1302 such that a recess of the connector engages an SFP latch. Figure 13B shows the narrow pitch connector 1300 inserted into a narrow pitch adapter 1304 such that a recess of the connector engages a latch of the adapter.

FIG. 14 shows a side view of the narrow width connector 1300 of FIG. 13A coupled with the narrow width SFP 1302 . Details of this coupling are shown within circle 1400 . Specifically, the SFP 1302 includes an SFP latch 1402 . The connector 1300 includes a recess 1404 . For example, the connector housing can include a recess 1404 . The pull tab 1406 can be spring loaded as described in various embodiments. This allows the pull tab 1406 to return to a position that allows the SFP latch 1402 to engage the connector recess 1404 . When the pull tab 1406 is in the normal pull tab position pushed forward by a spring, as shown in FIG. 14 , the SFP latch 1402 engages the connector recesses 1404 .

FIG. 15 shows a side view of the narrow width connector 1300 of FIG. 13A separated from the narrow width SFP 1302 . Details of this separation are shown within circle 1500 . The pull tab 1406 includes a tapered or sloped region 1502 . When the pull tab 1406 faces the arrow as shown in the figure When the direction of 1504 is pulled back, the SFP latch 1402 is lifted by the sloped region 1502 of the pull-back tab, thereby separating the SFP latch 1402 from the connector, as shown within the circle 1500 . The same effects described herein with respect to FIG. 15 are also produced in other embodiments of connectors coupled to a narrow width adapter as shown, for example, in FIG. 13A.

Although Figures 14 and 15 show the connector coupled to a narrow width SFP, in other embodiments the connector could couple to a narrow width adapter having an adapter latch similar to the SFP latch. Additionally, while the embodiment shown in Figures 13A, 13B, 14 and 15 includes a narrow width multi-fiber connector, other embodiments may include narrow pitch LC connectors.

16A-22 show various views and details of a narrow pitch multi-fiber connector, an SFP, and its associated latch mechanism in accordance with various aspects of the present invention. In one example, as shown in Figure 16B, the connector includes a connector plug frame 1601 (tip), LC type ferrule 1602, ferrule spring 1603, a connector rear body 1604 (one-piece backpost), a clip Ring 1605 , a cover 1606 , a pull piece return spring 1608 and a push/pull piece 1610 . Figure 17C shows the dimensions of the plug frame embedded in the QSFP. Figure 17D shows the QSFP latch recess 1607 with the push/pull tab in the normal position (pushed forward by the inner tab return spring). Figure 17E shows the QSFP latch recess 1607 with the push/pull tab in the retracted position (pushed forward by the inner tab return spring). 18A and 18C show a transceiver 1800 (QSFP) with a QSFP bend latch 1801 . Figure 19 shows a QSFP plugged into a dual ferrule connector. Figure 20A shows the connector latch recess 2011, and shows that the QSFP latch 2001 holds the connector push/pull tab in the normal position (by a reset spring). spring pushes forward). Figure 21 shows a QSFP plugged into a dual ferrule connector (push/pull tab pulled back). Figure 22A shows that the QSFP flex latch 2001 is lifted by pulling back the angled feature 2012 of the push/pull tab, and the QSFP latch is raised enough to unlock the connector.

The various connectors described herein coexist with various methods of implementation. Referring now to Figure 23A, an embodiment of a CS connector is shown exploded for details. It should be understood that this intuitive example is for illustration and that various alternatives may exist, and some are described here. In certain embodiments, a CS connector may be a miniature single position plug that generally features dual cylindrical spring-loaded mating ferrules approximately 1.25 mm in diameter, and a push-pull coupling mechanism. In some embodiments, the optical alignment mechanism of the connectors has a rigid hole or a resilient sleeve type.

In some embodiments, the CS connector may include a front body (ie, plug frame) 2301 that houses the ferrule(s) and ferrule flange(s) 2302 . A rear body (ie, back post) 2304 can be connected to the rear of the front body 2301 and accommodate the ferrule flange(s) 2302 . The ferrule flange(s) 2302 may be held in place using one or more springs 2303 . As shown, the rear body 2304 may include a clamp ring 2305 attached to the rear of the rear body. In some embodiments, a cable cover 2306 may surround the clamp ring 2305 . In certain embodiments and as shown, a dust cover 2307 may be placed over the front body 2301 to protect ferrules contained in the front body from damage and/or to keep debris out.

In other embodiments, a push-pull tab 2310 may be attached to the CS connector as described in more detail herein. The push-pull sheet 2310 can have There is a side portion 2312 and a central protrusion (ie, 2313 ) for various functions described further herein. The push-pull sheet 2310 can use a piece of spring 2308 to exert a constant directional force on the push-pull sheet to achieve the various advantages described herein. Referring briefly to Figure 23B, an embodiment of a combined CS connector with a push-pull tab is shown. In some embodiments and as shown, the push-pull tab 2310 has a front portion 2314 positioned in a recess 2317 in the front body 2301 . Thus, the front portion 2314 moves independently of the front body 2301 as the push-pull tab 2310 passes through the connector, as detailed herein.

In one or more embodiments and as shown in Figure 24A, a CS connector may have an overall dimensional width of 7.95mm. Furthermore, in another embodiment, the CS connector may have a pitch of 3.8mm. As described herein, the pitch is defined as the axis-to-axis distance between the central axes of the CS connectors 2450 . Furthermore, as shown in FIG. 24B , when the push-pull tab 2410 is attached to the front body 2401 and the rear body 2404 , an embodiment may have an overall dimensional height of 10.46 mm.

As described herein, a connector (eg, a CS connector) can have a push-pull tab for easy insertion into and extraction from an adapter. Referring to FIGS. 25A and 25B , in some embodiments, the push-pull piece 2510 can slide back and forth relative to the connector in a longitudinal manner, as shown by double arrows 2511 in dotted lines. FIG. 25A shows an embodiment where the side portion 2512 of the push-pull piece 2510 contacts the rear body 2504 . Contact between the side portion 2512 and the rear body 2504 stops the push-pull piece 2510 from moving forward.

In another embodiment, the push-pull piece 2510 can move far A distance 2513 from the rear body of about 1 mm to about 3 mm. The push-pull tab 2510 may have a central protrusion (eg, 2314 in FIG. 23A ) in contact with the rear body 2504 . The contact between the central protrusion 2514 and the rear body 2504 can stop the push-pull piece 2510 from moving backward.

Referring to Figures 26A-C, a CS connector is shown in accordance with some embodiments. As described herein, the push-pull tab has a front portion 2614 . In some embodiments, the front portion 2614 can include a tip 2630 . The tip 2630 may include a slot or groove (not shown) that slides over a portion of the front body 2601 to positively secure the front portion 2614 to the front body 2601 . In some embodiments, the slot or slot can be large enough to accommodate movement of the push-pull tab as described herein. In other words, when the push-pull tab is pulled away from the front body (see FIG. 25B and corresponding description), the push-pull tab can slide along the front body (ie, FIG. 26C ), so the slit or groove must be large enough Allowing the push-pull to move also ensures that one is positively attached in the non-retracted state (ie, Figure 26B).

As shown in Figure 27A and as described herein, an embodiment may include a spring 2708 (ie, Figure 23A, 2308). The spring 2708 applies a biasing force to the push-pull piece 2710 in a forward direction such that the slots of the front body 2701 and the push-pull piece 2710 are aligned as described herein and shown in FIG. 42 . As shown in FIG. 27A , the hidden lines show the spring 2708 inside the push-pull piece 2710 . In other embodiments, the push-pull piece 2710 may include a wedge portion 2731 . The wedge 2731 is assembled so that it snaps into the front body 2701 and slides/passes through the recess as the push-pull tab moves along the housing (ie, front and rear bodies) (see FIG. 23A 2317).

Referring now to Figures 28A/B/C, there is shown a CS connector including cross-sectional views of various embodiments. Figure 28A shows an example of a CS connector with two separate marked cross-sectional areas in accordance with certain embodiments. The first cross-sectional area (ie, X-X) is shown in more detail in Figure 28B. FIG. 28B shows how the wedge 2831 snaps into or connects to the front body 2801 . It should be appreciated that the material strength of the wedge 2831 ensures a positive connection to the front body 2801 while also allowing the push-pull tab 2810 to move along the length of the front body 2801 as further detailed herein. In addition to the wedge portion 2831, certain embodiments may also have another positive connection means comprising one or more clips 2832 formed as part of the push-pull tab. In certain embodiments and as shown, the one or more clips 2832 are attached to and snap into the front body 2801 and positioned adjacent to the body 2804 after insertion into the front body. It should be understood that these are non-limiting examples and that various attachment means may be used to secure the push-pull tab 2810 to the housing. In detail, the wedge portion 2831 and the one or more clips 2832 can be disposed at various other positions on the push-pull sheet 2810 and different positions on the front body 2801 and the rear body 2804 .

The connectors disclosed herein (eg, CS connectors) can be plugged into an adapter (eg, a fiber optic port), such as a fiber optic array or server. A non-limiting illustrative example of a typical adapter is shown in Figure 30A. Figure 30A shows a dual adapter to accept two connectors (eg, a dual ferrule CS connector). It should be understood that the various dimensions provided herein are for illustration only, and that various other dimensions are possible in various embodiments. Figures 30B and 30C show specific cross-sectional sections of the adapter shown in Figure 30A. Figure 30A, Various sizes of 30B and 30C are listed in Table 1 below. As shown in Figures 31, 32 and 33 and described herein, the receiver/transceiver is insertable into an anchoring device.

It should be appreciated that the various parts of a connector system (eg, CS connector system) can be adjusted in many ways to suit various situations. A non-limiting example of these variations is shown in Figure 29, which shows push-pull tabs 2910 constructed with different lengths.

The embodiment shown in Figures 30A, 30B and 30C shows an adapter that can accommodate various modifications. For example, and referring to Figures 31A, 31B and 31C, in some embodiments, a detachable adapter modification (eg, the hook system of Figures 31B and 31C) can be inserted into the adapter shown in Figure 31A. The detachable modification device, as shown in Figures 31B and 31C, may include a hook tip end 3121 and a hook bevel 3122, or any of a plurality thereof (eg, as shown, the modification device includes two hook tips).

It should be understood that the type and design of the detachable modification device (ie, interchangeable anchoring device) may vary. Figures 32A, 32B and 32C provide an illustrative, non-limiting example of one possible design for the interchangeable anchoring device. As described herein, in certain embodiments, a detachable adapter modification (eg, the hook system of Figures 32B and 32C) can be inserted into the adapter shown in Figure 32A. The detachable modification device, as shown in FIGS. 32B and 32C , can include a hook tip 3221 and a hook slope 3222 , or any of many of them (eg, as shown, the modification device includes two hook tips).

In another embodiment, and as shown in Figures 33A, 33B and 33C, a detachable adapter modification (eg, the hook system of Figures 33B and 33C) can be inserted into the adapter shown in Figure 33A. The detachable modification device, as shown in FIGS. 33B and 33C , can include a hook tip 3321 and a hook slope 3322 , or any of a number of them (eg, as shown, the modification device includes two hook tips).

FIG. 34 shows a dual adapter similar to that shown in FIG. 30A to accept two connectors (eg, a dual ferrule CS connector), however, FIG. 34 includes two separable modification devices 3420 . It should be understood that the various dimensions provided here are for illustration only, and that various other dimensions are possible in various embodiments. 35A and 35B show specific cross-sectional sections of the adapter shown in FIG. 34, and thus the labeled dimensions of FIGS. 34, 35A and 35B are also listed in Table 1.

Referring now to Figures 36A and 36B, a CS connection An illustration of a connector being inserted into an adapter. As described herein, the illustrated adapter includes modifications to engage most of the CS connector as described in detail below. Figure 37 shows a CS connector plugged into an adapter. The modification device 3720 strikes and interacts with the CS connector when the connector is inserted into the adapter housing. In certain embodiments, when the CS connector is inserted, the front of the CS connector contacts the hook ramp (3522 of FIG. 35C, 3222 of FIGS. 32B and 32C, and 3322 of FIGS. 33B and 33C), and the hook ramp Elevate the portion of the modification device that interacts with the CS connector.

Still referring to FIG. 37 , the movement of the modifying device is shown in enlarged views 3731 and 3732 . As shown, the hidden (eg, dashed) lines represent the contoured hook slopes 3122, 3222, and 3322, and the solid lines represent the contours of the hook tips 3121, 3221, and 3321. The hooks 3121, 3221 and 3321 are raised above the surface of the connector to allow the connector to be inserted into the adapter. After the connector reaches its intended destination within the adapter (eg, when a positive fiber optic connection is made), the hook tips 3121, 3221, and 3321 interlock with a recess 3709 on the connector. This interlocking action secures the connector within the adapter housing by the tab during a push-in action.

Referring now to Figure 38, it is important to note that the front portion 3814 of the push-pull tab 3810 moves independently of the front body 3801 as described herein. Therefore, the enlarged front portion 3814 of the push-pull piece 3810 can be aligned with the concave portion 3816 of the front body 3801 . In this configuration, the hook points 3121, 3221 and 3321 securely secure the connector to the suitable on the orchestrator. However, according to different embodiments, the push-pull sheet 3810 can move forward or backward (see FIGS. 31 , 32 and 33 ), so that the recesses 3816 are not aligned with the recesses of the push-pull sheet. When the front portion 3814 of the push-pull piece 3810 moves out of alignment, it interacts with the hook slopes 3122, 3222, and 3322 through the slope 3815. Thus, in some embodiments, moving the push-pull tab 3810 independently of the front body 3801 may allow the sloped region 3815 to apply a force to the hook slopes 3122, 3222, and 3322, thereby raising the hook tips 3121 , 3221 and 3321. After lifting the hook tips 3121, 3221 and 3321, the connector can be safely removed by the adapter and/or transceiver.

39-41 further show enlarged and cross-sectional views of a connector that interacts with an adapter and/or transceiver. Figure 39A shows the push-pull tab 3910 and the sloped area 3911 of the push-pull tab, and Figure 39B shows the plastic hook tip 3901 in the recess of the connector body. Figure 40 shows the push-pull tab 4010 and the inclined area 4011 of the push-pull tab and the plastic hook tip 4001 in the recess of the connector body. Figure 41 shows that when the connector is inserted into the transceiver/adapter, the push-pull angled area 4111 raises the hook. In addition, FIGS. 42 and 43 further show an enlarged view and possible dimensions of an embodiment, please refer to Table 2.

Using a CS connector results in a compact fiber embodiment and improved flexibility. For example, in some existing systems, a 200G transceiver module 4401 can accommodate an MPO connector 4402 as shown in FIG. 44A . Should The MPO connectors can then be separated using another tool such as a fan out 4403 or a box 4406 . After the cable is detached, it can be connected to a 100G modular device (eg, an LC uniboot as shown) 4404 . The 100G modular device 4404 can then be plugged into a 100G transceiver 4405 .

Alternatively, in some embodiments, and as shown in FIG. 44B , multiple CS connectors 4406 plug into a 200G transceiver module 4401 . Each CS connector 4406 can then be connected to the 100 independently as shown in FIG. 44A , and a 200G transceiver module 4401 can receive an MPO connector 4402 . The MPO connector can then be separated using another tool such as a fan out 4403 or a cassette 4406 . After the cable is detached, it can be connected to a 100G modular device (eg, an LC uniboot as shown) 4404 . The 100G module device 4404 can then be plugged into a 100G transceiver module 4405 .

Shown in FIG. 14 for purposes of illustration only is a specific example using multiple bundles of cables, and it should be understood that virtually unlimited alternatives and modifications are possible. As shown, a switch (eg, 100G switch) 1430 is shown having a transceiver (eg, 100G transceiver) 1431 . The transceiver 1431 has an adapter that accommodates one of the two mini-CS duplex connectors 1432 . From each of the two duplex connectors 1432, a four fiber optic cable 1433 extends and connects with various other connectors and transceivers. As shown, a four-fiber cable 1433 splits into two-fiber cables 1434, and the two-fiber cables 1434 are then attached to a single CS simplex connector 1435 and placed into a transceiver (e.g., 25G receptacle) 1436 . As further shown, one of the four-fiber cables 1437 is connected to a single mini-CS duplex connector 1438, and the single mini-CS duplex connector 1438 Then plug into another transceiver (eg, a 50G transceiver) 1439 .
