Detailed ways

In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The jumper is used as a jumper from equipment to equipment, or from equipment to optical fiber wiring links. It has a thicker protective layer and is generally used for the connection between optical transceivers and terminal boxes. Fiber jumpers can be divided into single-mode fiber jumpers and multi-mode fiber jumpers. According to different transmission media, the fiber jumper can also be divided into silicon-based fiber jumper, fiber jumper with plastic, etc. as the transmission medium. According to the structure of the fiber optic connector, the jumper can be divided into: FC jumper, SC jumper, ST jumper, LC jumper, MTRJ jumper, MPO jumper, MU jumper, SMA jumper, FDDI jumper, E2000 jumper Fiber, DIN4 jumper, D4 jumper and so on various forms. Other common fiber jumper forms are FC-FC, FC-SC, FC-LC, FC-ST, SC-SC, SC-ST, etc.

Single-mode fiber jumpers are generally indicated in yellow, and the connectors and protective sleeves are blue; the transmission distance is longer. Multimode fiber jumpers are generally indicated in orange, and some are indicated in gray, and the connectors and protective sleeves are in beige or black; the transmission distance is relatively short. Fiber jumper products are widely used in communication equipment room, fiber to the home, local area network, fiber optic sensor, fiber optic communication system, fiber optic connection transmission equipment, national defense combat readiness and other fields.

Fig. 1 exemplarily shows a structural diagram of a fiber jumper in the prior art. FIG. 1 a shows a schematic diagram of the cross-sectional view seen along position A-A in FIG. 1 . As shown in FIG. 1 and FIG. 1a, it is a schematic structural diagram of a fiber jumper in the prior art. It includes a wire core 101, the wire core 101 is encapsulated in a glass envelope 102, the glass envelope 102 is encapsulated in a jacket 103, and the end of the wire core 101 is provided with an optical fiber connector 104.

The core 101 is used to transmit optical signals. The glass envelope 102 is used to encapsulate the wire core 101 , so that the optical signal in the wire core 101 can be normally transmitted in the wire core 101 . An optical fiber connector 104 is provided at the end of the core 101, and the optical fiber connector 104 can be movably inserted into other optical fibers, and the optical fiber connector is used to realize the flexible connection of the optical path. The specifications of the optical fiber connector 104 match the sockets of other optical fibers or sockets of other adapters. In specific implementation, jumpers with different optical fiber connectors can be selected according to different shapes of optical fiber sockets. The core 101 may only have one optical fiber connector 104, and in this case the core 101 becomes a pigtail.

The fiber jumper has no mesh shielding layer. In the multimode fiber jumper, the diameter of the core 101 is 50 μm to 65 μm, roughly equivalent to the thickness of a human hair. In the single-mode fiber jumper, the diameter of the core 101 is 8 μm to 10 μm, and the core 101 is surrounded by a layer of glass envelope 102 with a lower refractive index than the core 101 to keep the light in the core 101, and the glass envelope 102 encapsulates In the jacket 103 , the jacket 103 is used to protect the wire core 101 and the glass envelope 102 .

The jacket 103 of the fiber jumper is usually yellow or red or blue. Usually, when one end of the fiber jumper fails, the location of the device can be quickly determined through the identification number in the fault information reported by the device, and then according to the fault information The identification number of the faulty port can quickly determine one end of the jumper connected to the faulty port, but it is difficult to quickly find the other end of the faulty jumper in a computer room with a large number of jumpers. Based on this, an embodiment of the present invention provides a fiber jumper, which is used to quickly find the other end of the fiber jumper.

Fig. 2 exemplarily shows a schematic structural diagram of a fiber jumper provided by an embodiment of the present invention.

Based on the foregoing, Fig. 2 shows a fiber jumper provided by an embodiment of the present invention, including a core 101, the core 101 is encapsulated in a glass envelope 102, the glass envelope 102 is encapsulated in a jacket 201, and the end of the core 101 is provided with an optical fiber The connector 104 and the jacket 201 are provided with jacks 203, the jacks 203 are used for plugging the input end plug of the visible light source, and the jacket 201 is made of a material capable of scattering light.

Because the jacket 201 of the fiber jumper is provided with a jack 203, the jack 203 can be connected to the plug of the input end of the visible light source, and the visible light output by the visible light source enters the jacket 201 from the jack 203, further because the material of the jacket 201 of the fiber jumper is energy Light-scattering material, so the jacket 201 of the fiber jumper can scatter the visible light input into the jacket, at this time, the user can see the light around the entire jumper fiber, that is, the user sees the visible light scattered by the jacket of the jumper fiber, and then the user can According to the luminous jumper, quickly identify the other end of the jumper.

Preferably, the visible light source in the embodiment of the present invention may be an infrared visible light source, or visible light of other colors, which is not specifically limited in the embodiment of the present invention.

Preferably, the shape of the jack 203 matches the shape of the plug at the input end of the visible light source. Specifically, the plug at the input end of the visible light source can have various specifications. The jack 203 in the embodiment of the present invention is used to connect an optical fiber that can output visible light, so the shape of the jack should match the plug at the input end of the visible light source. In this way, the plug at the input end of the visible light source can be flexibly inserted and removed from the jack.

Preferably, the material of the coat 201 is a transparent material. Specifically, when the material of the jacket 201 is transparent, the visible light scattered by the jacket 201 is easier to be observed by people.

The optical fiber made of PMMA and fluorine-containing polymer is Plastic Optical Fiber (POF for short). The plastic optical fiber is an optical fiber made of a light-transmitting polymer. The technology is mature and the process is simple, so the cost of the optical fiber is low, and it is soft and strong. The diameter of the plastic optical fiber is relatively large, about 1 mm, and the loss is low.

Preferably, a protrusion is provided on the surface of the jacket, the insertion hole is disposed on the first end face of the protrusion, and the first end face is parallel to the end face of the fiber jumper.

There are two jacks 203, and each jack is respectively set on the jacket at a position close to an optical fiber connector, that is, the two jacks are respectively set at the root of the jumper fiber. When any end of the jumper is damaged, visible light can be input to the jumper through the jack at the damaged end of the jumper, so as to quickly find the other end of the jumper.

Specifically, the positions of the two jacks do not need to be arranged symmetrically along the center line as shown in FIG. 2 , but as shown in FIG. 2 b , the positions of the two jacks on the casing 209 are located on the same side of the periphery of the casing.

Specifically, as shown in FIG. 4 , one end of the core 101 is provided with an optical fiber connector 403 , and the other end is not provided with an optical fiber connector. Preferably, the optical fiber can be a pigtail. An insertion hole 402 is arranged on the jacket 401 of the optical fiber. Usually the end with the connector 403 will fail, so the visible light is input to the jumper through the jack at this end, so as to quickly find the other end of the jumper.
