Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical connection component for interconnecting optical elements, components, and devices used for optical communication such as optical devices, optical circuit packages, optical circuit devices, and optical information processing. And an optical fiber wiring method.

[0002]

2. Description of the Related Art Generally, an optical element or an optical circuit package is used for connection of a plurality of optical elements in an optical circuit package, for mutual connection between a plurality of optical circuit packages, or for optical connection of an optical circuit device mounting the optical circuit package. An optical connector is arranged at the end of an optical circuit device or the like and is connected to each other by an optical fiber. In that case, since the optical fiber needs to be arranged with an extra length, for example, on the optical circuit package or inside and / or on the back surface of the optical circuit device, complicated wiring by the optical fiber has a bird's nest shape, Or, it is congested and stretched, and for that reason, it occupies a large space. For an optical connection method that requires a great deal of place and labor for connection due to such complicated wiring, it is easy to solve these problems by arbitrarily wiring the optical fiber on a two-dimensional plane. A method has been proposed. For example, Japanese Patent No. 2574611 and Japanese Patent No. 2807403.
There is proposed an optical connecting component using a sheet or substrate coated with an adhesive and fixing an optical fiber by using the sheet or the substrate coated with an adhesive, as disclosed in Japanese Patent Laid-open Publication.

However, in the optical fiber wiring patterns of these optical connection parts, the optical fibers wired from one port are spread in a lattice or radial pattern, and there are many portions where the optical fibers intersect with each other. Since the crossing portion is widely present in the entire optical connecting component and the respective optical fibers are wired so as to intersect with each other, especially when the optical connecting component is made small, the interval between the optical fibers becomes narrow, and therefore, When the optical fibers cross and get over, the contact length of the optical fibers to the adhesive becomes small, the wiring pattern is destroyed, and accurate wiring of the optical fibers cannot be performed. Further, when the wiring density of the optical fibers is increased, the overlapping due to the intersection of the optical fibers is increased, and the contact length of the optical fibers with the adhesive is reduced as in the above case, so that the optical fibers cannot be accurately wired.
Further, when the number of overlapping optical fibers is increased, the flexibility of the optical connecting parts is lost, so that the connection of the optical elements in the small circuit packages and the mutual connection of the optical circuit packages in a small space,
Alternatively, it is difficult to use for optical connection of an optical circuit device equipped with an optical circuit package.

In order to facilitate the wiring design or wiring work, it is desirable to sequentially wire each port.
When the optical fibers wired from each port as described above are wired in a lattice pattern or in a radial pattern, by wiring for each port, the number of overlapping optical fibers due to the intersection of the optical fibers increases, and There has been a problem that the collapse and the flexibility of the optical connecting parts are lost.

[0005]

SUMMARY OF THE INVENTION The present invention has been made for the purpose of solving the above-mentioned problems in the prior art. That is, according to the present invention, when a plurality of optical fibers that are convergingly wired as described above are wired to fabricate an optical connection component, the design of the optical fiber wiring is easy, and the wiring is small (small area). And to provide a wiring method with good wiring workability. Another object of the present invention is to provide an optical connecting component having an optical fiber wiring pattern wired by the above wiring method and having good connectivity with an optical circuit package or the like in a small space.

It has a wiring pattern formed by wiring each optical fiber between the ports.

Further, the optical fiber wiring method of the optical connecting component of the present invention is such that a plurality of optical fibers having a terminal portion for optical connection to an end are divided into a plurality of ports and are two-dimensionally planarized on a base material.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a partially fragmented plan view of a typical example of the optical connecting component of the present invention, in which an end portion of an optical fiber 13 serves as a terminal portion 14 for optical connection, and an optical component 15, for example, Optical connector is connected. FIG. 2 is a cross-sectional view of an example of the optical connection component of the present invention, in which an optical fiber 13 is wired on a base material 11 via an adhesive layer 12, and an adhesive layer 12 'is provided on the base. The material 11 'is laminated by sticking.

When manufacturing the optical connecting component of the present invention, an adhesive layer may be provided on the substrate and the optical fiber may be wired thereon. The present invention is characterized by an optical fiber wiring method. In the present invention, a wiring route is first set when wiring an optical fiber.
FIG. 3 is a diagram showing an example of a wiring path for wiring an optical fiber. First, a plurality of virtual ports are divided into two groups and set so as to face each other.

For example, as shown in FIG. 3, a plurality of virtual ports for input / output ports are group I (virtual port 1a).
.About.1h) and group II (virtual ports 2a to 2h) are set so as to be arranged at predetermined positions on the base material.
Specifically, a mark is provided on the base material. Then, the outermost virtual ports 1a and 1h of the group I and the outermost virtual ports 2a and 2h of the group II are connected so as to intersect each other, and two design lines 3 (3
a, 3b), and connecting designating virtual ports of group I and virtual ports of group II so as not to intersect each other to draw design lines 4a to 4h, and Line 3 (3
a, 3b) and 4 (4a to 4h) are wiring paths for wiring. Wiring of the optical fiber may be performed by connecting desired virtual ports to the virtual ports along the wiring paths. An optical fiber is wired on each virtual port to form a port. Since the virtual port is for setting the wiring route, the optical fiber does not need to be wired in all of the virtual port and the wiring route.

As described above, by setting the wiring route, the wiring can be given a general regularity, the wiring pattern can be easily designed, the design time can be shortened, and the wiring can be efficiently arranged. It will be possible to do. Further, the crossing positions of the optical fibers are limited and reduced, the number of overlaps at the crossing portions can be reduced, the flexibility of the optical connecting component can be improved, and the size can be reduced. Furthermore, as shown in FIG. 3, since the wiring path can be set by a straight line, the length of the optical fiber to be wired can be shortened, which is economically advantageous.

The design line 4 connecting the virtual ports is a polygonal line, a circular arc, if they do not intersect each other.
Although it may be a line of any shape such as a free curve, it is preferably a straight line. Further, the position of each port of the input / output port may be arranged at any position of the optical connecting component as long as the arbitrary line is drawn. Further, the number of optical fibers wired to each port may be the same or different.

Next, a more specific example of the optical fiber wiring method of the present invention will be described with reference to the drawings. Figure 4
Is a wiring path from the virtual port (FIG. 4A) and a wiring pattern of the wired optical fiber (when there are eight input / output ports and each port is composed of four optical fibers). FIG.4 (b)) is shown. 5-13
FIG. 4B is an enlarged view of a portion B of FIG. 4B, showing an example of a wiring state of the optical fiber routed in the wiring path of the portion B of FIG. 4A.

In FIG. 4, between the outermost virtual port 1a of group I and the outermost virtual port 2d of group II, and between the outermost virtual port 1d of group I and the outermost side of group II. Design lines 3a and 3b connecting between a certain virtual port 2a and a design line 4 connecting between a virtual port paired with each other.
Optical fibers a to p are wired along a to 4 d.
Note that 1A to D and 2A to 2D are ports formed as virtual ports.

FIG. 5 shows, in the part (b) of FIG. 4 (b),
The optical fibers a to d wired to the port 1A are branched into a, b and c, d, and one of them, c and d, is the design line 3
At the position where a and design line 4b intersect, port 1
One of the branched optical fibers e to h wired to B,
It shows a state where the wiring is merged with f. 6 and 7
5 is similar to the case of FIG. 5, but an example in which the arrangement order of the optical fibers is changed when the optical fibers c and d wired to the port 1A and the optical fibers e and f wired to the port 1B are joined. Is. In the case of FIG. 8, the arrangement order of the branched optical fibers a and c from the port 1A is exchanged, and one branched optical fiber b and d is arranged with the branched optical fibers e and g from the port 1B. This is an example in which the order is changed and merged.

In the case of FIG. 9, of the optical fibers c and d branched from the port 1A, the optical fiber c merges with the branched optical fiber f from the port 1B, and the optical fiber d
And an optical fiber e from the port 1B are connected to each other, and are wired so as to communicate with the ports 1A and 1B. In the case of FIG. 10, FIG.
A wiring pattern similar to that in the above case is formed, but the arrangement order is changed. That is, the optical fiber b branched from the port 1A and the optical fiber f from the port 1B are connected to each other and are wired so as to communicate with the ports 1A and 1B. The optical fiber g branched from the port 1B joins the optical fiber d.

Further, in FIG. 11, in the portion B of FIG. 4B, the optical fibers a to d wired to the port 1A are
4 is divided into a, b and c, d, one of which is c, d.
At the position where the design line 3a and the design line 4b in (a) intersect, the optical fibers e to h wired to the port 1B.
After crossing one of the branched ones e and f, the wiring is merged with the other branched g and h. The branched optical fibers a and b from the port 1A join the optical fibers e and f from the port 1B. 12 and 13 are similar to the case of FIG. 11, but in FIG. 12, the optical fibers a and b wired to the port 1A intersect the optical fibers e and f wired to the port 1B, The optical fibers g and h that are branched are joined together, while the optical fibers c and d from the port 1A are connected to the optical fiber e from the port 1B
In FIG. 13, when the optical fibers from the port 1A are merged, the arrangement order of the optical fibers is changed.

In the present invention, the term "branching" means that a plurality of optical fibers are separated at a virtual port portion or a crossing portion of a wiring route and are wired along different design lines. , Means that the optical fiber intersects with the optical fiber routed along another design line at the intersection of the wiring route. The intersection for changing the arrangement order of the optical fibers does not mean the above intersection. Further, the term "merge" means that the optical fibers are wired along the same design line together with the optical fibers wired along the other design lines.

In the present invention, the number of optical fibers to be branched, crossed, or merged is not particularly limited and can be freely set. Further, the optical fiber does not have to be routed along all the design lines in the route. Further, the number of virtual ports needs to be set so that three or more exist in one group .

In the above description, the case where the ports are provided at both side edges of the base material has been described, but the virtual ports for forming the ports do not necessarily have to be provided at both side edge edges of the base material. 14 to 17 show examples of wiring paths. In the figure, 1a to 1h indicate virtual ports of group I and 2a to 2h indicate virtual ports of group II. In any of the examples, two design lines 3 that connect the outermost virtual ports 1a and 2h, 1h and 2a of each group so as to intersect each other are drawn, and each pair of virtual ports corresponds to each pair. A plurality of design lines 4 are drawn so as not to intersect each other. In the present invention, the optical fiber may be wired along the wiring path formed by these design lines. When the number of optical fibers and the number of ports increase, the number of optical fibers intersecting each other increases at the intersection of two design lines connecting the virtual ports, so that the area of the intersecting optical fibers increases. . As a result, the optical fibers that are wired on the design line that connects the virtual port pairs will also intersect, the number of optical fibers that overlap will increase, and the wiring pattern may collapse. In this case, connect the virtual ports to 2
The problem is solved if the area of the intersection is widened by widening the interval between the lines connecting the virtual port pairs on both sides of the intersection of the book design lines, for example, the ports 1d-1e in FIG. be able to.

In the present invention, one of the optical fibers branched along the wiring path as described above is joined with the other optical fiber, so that the optical fibers of the central portion or ports in the same direction can be collected and wired. Therefore, it is possible to perform wiring in a small area without expanding the wiring pattern as in the case of conventional wiring in which random or branching and crossing are repeated. Further, since branching, crossing, and merging may be performed along the wiring route, the wiring route can be easily changed, and free access wiring can be easily performed to a desired port. Further, by collecting the intersections at the intersections of the wiring paths, it is possible to reduce the number of the intersections, and further, the overlapping of the optical fibers at the intersections can be reduced to two.
It can be a book.

In the optical connecting component of the present invention, the flexible base material having a two-dimensional plane for supporting the wired optical fiber is not particularly limited, and for example, glass-epoxy resin composite. Substrate, polyester film, polyimide film, gel-like material of organic material such as silicone or urethane resin, rubber-like or foam-like material, and any base material used for ordinary electronic parts and electric parts It is possible to Further, the optical connecting component of the present invention does not need to be flexible depending on the purpose of use and may be rigid. For example, a substrate made of a rigid polymer material, a ceramic substrate, or the like can be used, and any shape can be used.

The optical fiber wired in the present invention is appropriately selected and used according to the application purpose of the optical connecting component, and for example, quartz or plastic single mode optical fiber, multimode optical fiber, etc. are preferably used. It

In order to manufacture the optical connecting component of the present invention, an optical fiber may be wired on the above base material. The simplest method for wiring the optical fiber on the base material is to provide an adhesive layer on the base material. In this case, as the adhesive forming the adhesive layer, any adhesive can be used as long as it has an adhesive force that maintains the shape of the optical fiber against the tension generated by bending of the optical fiber to be wired. For example, various pressure-sensitive adhesives (adhesives) such as urethane-based, acrylic-based, epoxy-based, nylon-based, phenol-based, polyimide-based, vinyl-based, silicone-based, rubber-based, fluorinated epoxy-based, fluorinated acrylic-based, etc. A thermoplastic adhesive or a thermosetting adhesive can be used. A pressure sensitive adhesive and a thermoplastic adhesive are preferably used because of the ease of wiring the optical fiber.

For the optical connecting component of the present invention, a structure suitable for the purpose of use may be appropriately selected and used, and the structure is not particularly limited. Further, the manufacturing method thereof may be appropriately selected and used, and there is no particular limitation. For example, the same base material as described above provided with an adhesive layer may be attached onto the wired optical fiber to form a laminated structure.

In the optical connecting part of the present invention, normally,
For connection with the optical connector, an optical fiber is drawn out from a desired port on the end face of the optical connection component body to form a terminal portion, to which the optical connector is connected or is connected to the optical connector. It is fusion-spliced with the optical fiber. The optical connector connected to the optical connecting component of the present invention is not particularly limited, but a single-core or multi-core small-sized optical connector is preferably selected. For example, MPO optical connector, MT
Optical connector, MU optical connector, FPC optical connector (NT
TR & D, Vol. 45 No. 6, p. 589),
Alternatively, a V-groove component used for optical connection may be used. The method of connecting the optical connector is not limited at all, and the end portion and the optical connector may be integrated.

Example 1 30% ethyl acetate of acrylic resin composed of n-butyl acrylate / methyl acrylate / acrylic acid / 2-hydroxyethyl methacrylate copolymer (= 82/15 / 2.7 / 0.3 (weight ratio)) To 100 parts of the solution, 1.0 part of Coronate L (manufactured by Nippon Polyurethane Industry Co., Ltd.) was mixed and mixed. The resulting coating liquid for acrylic pressure-sensitive adhesive (adhesive) was roll-coated to a thickness of 12
A 5 μm polyimide film is evenly applied to one surface so that the film thickness after drying is 100 μm, and an acrylic adhesive layer is formed to form an adhesive sheet (size 70 mm × 50 m).
Two sheets of m) were produced. In addition, a virtual port was previously set on one surface of one polyimide film as shown in FIG. 18, and a design line was drawn. That is, the group I (1a ...
1d) and group II (2a to 2d), arranged on opposite sides of the polyimide film so as to face each other, and the outermost virtual ports of each group (between 1a and 2d, 1d and 2a). ) Are drawn by two polygonal lines intersecting each other to draw the design line 3, and between the virtual ports (1a and 2a, 1b and 2b, which are opposed to each other) of each group.

Optical fibers a to d from the virtual port 1a are branched into a, b and c, d near the intersection A, a and b are in the direction of the intersection B, and c and d are in the direction of the intersection C along the design line. Wiring. The branched optical fiber a merged with another optical fiber in the vicinity of the intersection B, and was wired to the virtual port 2a, and the optical fiber b was wired to the virtual port 2b. The optical fibers c and d branched at the intersection A intersect with other optical fibers at the intersection C along the design line, and the optical fiber c is at the intersection E.

And showed sufficient flexibility. Further, since the number of overlaps was 2 or less, the contact area between the optical fiber and the adhesive layer was sufficient, and the collapse of the wiring pattern of the optical fiber after wiring and the floating of the optical fiber were not recognized. Furthermore, setting the wiring route is very easy,

Furthermore, the length of the optical fiber to be wired is shortened, which is economical.

Example 2 In Example 1, the size of the base sheet was 30 mm × 2.
An optical fiber was wired in the same manner as in Example 1 except that the pitch of each port was set to 5 mm, and the pitch of each port was set to 6 mm. As a result, it was possible to carry out wiring without breaking the wiring pattern of the optical fiber. When the loss of all the connected optical fibers was measured, it was 0.8 dB or less, including the connection loss of the optical connector, and it was found that it could be sufficiently used as an optical connecting part.
