Description

  The present invention relates to an optical fiber sheet in which a plurality of optical fibers are wired, a method for manufacturing the same, and an optical fiber wiring body, and more particularly, to an optical fiber that is rearranged and wired between an input port and an output port.

  An optical fiber in which a plurality of optical fibers are wired on a sheet substrate with an adhesive layer, a predetermined number of optical fibers are drawn out from the edge of the substrate for input ports and output ports, and a connector is attached to the leading end. Fiber sheets are being used for internal wiring of communication devices and computers. As an optical fiber used for such an optical fiber sheet, it is common to use an optical fiber that has been previously colored (the coating layer coated on the optical fiber is colored).

  By the way, in the optical fiber sheet described above, at least one of the input port and the output port, except when the input port and the output port are configured by one optical fiber wired in a single stroke. When there are a plurality of ones, there is a need for port identification when used. In this regard, when each of the plurality of ports is constituted by one optical fiber, the port can be easily identified by wiring using optical fibers of different colors. The same applies to the case where there is one input port constituted by an optical fiber group and a plurality of output ports dispersed in a dendritic shape.

However, when there are a plurality of input ports and output ports, each port is composed of an optical fiber group composed of a plurality of optical fibers, and matrix conversion wiring is performed between the input and output ports, it is difficult to identify the ports. It becomes. For example, as shown in FIG. 3, when each of the four input ports IN-1 to IN-4 is composed of optical fiber groups 1 to 4 made of four optical fibers, the optical fibers of the optical fiber group 1 A red colored layer, an optical fiber of the optical fiber group 2 having a yellow colored layer, an optical fiber of the optical fiber group 3 having an orange colored layer, and an optical fiber of the optical fiber group 4 If each is wired with a green colored layer, each port can be identified on the input port side. However, at the output port OUT-1, one of the red optical fibers at the input port IN-1 is wired, and one of each of the other input ports IN-2 to IN4 of yellow, orange, and green is connected. Wiring is performed, and the other output ports OUT-2 to OUT-4 have the same wiring pattern. In other words, in the output ports OUT-1 to OUT-4, the optical fibers of the respective colors are disturbed due to the matrix conversion wiring, and there is a problem that the output ports cannot be substantially distinguished from each other.

Therefore, in view of the above problems, an object of the present invention is to provide an optical fiber sheet capable of identifying a port, a manufacturing method thereof, and an optical fiber wiring body.

On the other hand, the optical fiber groups in the other input ports are different from each other in color, and each optical fiber in one output port is appropriately provided in the colored layer of the optical fiber in the middle of the recombination wiring. It is desirable that the same color and the optical fiber groups in other output ports be different from each other. Here, “recombination conversion” refers to an aspect in which a plurality of optical fibers of at least one input port are divided and wired into a plurality of output ports, and / or at least one output port receives light from a plurality of input ports. A mode in which fibers are wired.

It is applied at the time of optical fiber wiring.

  Furthermore, it is preferable to attach a multi-core optical connector to each input port and output port.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
FIG. 1 is a plan view showing an example of an optical fiber sheet 100 according to Embodiment 1 of the present invention, and FIG. 2 is an enlarged view of a portion A in FIG. As shown in the drawing, a large number of optical fibers are wired on the sheet substrate S, and the optical fibers are subjected to matrix conversion from the input ports IN-1 to IN-4 to the output ports OUT-1 to OUT-4. It is wired to be.

  That is, the input port IN-1 includes four optical fiber groups 1, of which the optical fiber 1a is to the output port OUT-1, the optical fiber 1b is to the output port OUT-2, and the optical fiber 1c is the output port OUT--. 3 and the optical fiber 1d are wired on the sheet substrate S so as to face the output port OUT-4. Similarly, in the optical fiber groups 2 to 4 in the input ports IN2 to IN-4, one optical fiber is wired to each of the output ports OUT-1 to OUT-4.

  Here, the optical fibers wired on the sheet substrate S are each provided with a colored layer on the outermost layer, and the color of the colored layer is changed on the substrate S as necessary. FIG. 2 shows an example. Assuming that the colored layer of the four optical fiber groups 1 at the input port IN-1 is red, one of the optical fibers 1a does not change the color of the color and directly goes to the output port OUT-1. Wiring.

  On the other hand, during the wiring on the sheet substrate S, the other optical fiber 1b changes its colored layer from red to yellow and is wired to the output port OUT-2. Similarly, the remaining optical fibers 1c and 1d are also changed in color from red to orange and from red to green, respectively, and are wired to the output ports OUT-3 and OUT-4. Further, the colored layer of the optical fiber group 2 of the input port IN-2 is yellow, the colored layer of the optical fiber group 3 of the input port IN-3 is orange, and the colored layer of the optical fiber group 4 of the input port IN-4 is green. Then, the color is changed except for one of the four optical fibers, and the wiring is respectively arranged in accordance with the color of the optical fiber in which the optical fiber group 1 is distributed to OUT-1 to OUT-4. Is going.

  In the optical fiber sheet 100 thus obtained, all the four optical fibers of the optical fiber group 10 at the output port OUT-1 gathered in red, and similarly, the optical fiber group at the output port OUT-2. 20 optical fibers are all yellow, optical fibers in the optical fiber group 30 at the output port OUT-3 are all orange, and optical fibers in the optical fiber group 10 at the output port OUT-4 are all green. Regardless of this, the port can be clearly identified not only on the input port side but also on the output port side.

  As the sheet substrate S used in the present invention, a sheet material provided with an adhesive layer capable of adhering and fixing optical fibers to be wired can be used. For example, a resin sheet made of polyimide resin, polyethylene terephthalate resin, polyethylene naphthalate resin, or the like can be suitably used. The adhesive layer is not particularly limited as long as it has adhesiveness or adhesiveness and can securely fix the optical fiber, and examples thereof include a silicone-based adhesive. In general, after an optical fiber is wired on the sheet substrate S, a protective sheet is placed on the optical fiber for the purpose of preventing wiring disturbance and protecting from damage. As the protective sheet, the above-described resin sheet can be used.

  For example, the optical fiber wiring on the sheet substrate S is performed by using a wiring device having a wiring head having a rotating optical fiber supply means such as a reel around which the optical fiber is wound. While drawing the desired pattern while feeding the fiber from the head and adhering it to the adhesive layer of the sheet substrate, the optical fiber is wired in a one-stroke shape via the route protruding from the edge of the sheet substrate S, and then It can be performed by a method of cutting an optical fiber at a protruding portion from the substrate.

  In the present invention, the plurality of optical fibers wired on the sheet substrate S must be wired so as to include an optical fiber with a color identification that can be visually recognized as different colors on the input port side and the output port side. I must. This color identification is performed by providing a colored coating around the outermost layer of the optical fiber strand as in the previous embodiment to form a colored layer, and this color is different between the input port side and the output port side. Alternatively, a mode in which line markers or dot marks of different colors are attached to the input port side and the output port side of optical fibers having the same base color may be used.

  Further, the color identification does not necessarily have to be performed over the entire length of the optical fiber, and it is sufficient that the color identification that can be visually recognized at least on the input port side and the output port side portion is performed. For example, the line marker may be attached to a part of the optical fiber extended from each port. Further, when a plurality of optical fibers are extended from each port, it is not necessary to attach a line marker or the like to all the optical fibers, and it is only necessary to attach to at least one optical fiber of each port.

  As described above, various methods can be employed for differentiating the color of the optical fiber on the input port side and the output port side, but from the viewpoint of manufacturing efficiency and aesthetics of the finished product, the color of the colored layer The replacement point is preferably located on the sheet substrate. Formation of such a color change point can be realized by adding a coloring mechanism to the optical fiber to the wiring device. That is, for example, in the above-described embodiment, a coloring head impregnated with colored inks of red, yellow, orange, and green is provided with a protruding and retracting mechanism that can come into contact with an optical fiber that is fed and advanced in the wiring head. In addition, the ink jet head is arranged so as to be ejectable with respect to the optical fiber, or the like.

  Then, while wiring the optical fiber with one stroke as described above, the color change point on the sheet substrate is calculated backward from the amount of the optical fiber fed, etc., and the appropriate color of the above-described coloring head or inkjet head is operated to make the optical fiber. Coloring may be performed. In addition, since it is sufficient if the optical fiber can be identified at the portion protruding from the substrate at the input / output port, that is, it is sufficient if the color is changed at any point on the sheet substrate, this color change is not necessarily a dimension. Precision is not required.

  A multi-core connector C is attached to the end of the optical fiber group of each of the input ports IN-1 to IN-4 and the output ports OUT-1 to OUT-4. The multi-core optical connector C is attached after the above-described wiring is completed, a light guide test or the like is performed, and unnecessary optical fibers are cut off. However, if the optical fiber sheet 100 of the present invention is used, Since the output ports are clearly color-coded for the output ports, no mistakes will occur when attaching the multi-core optical connector C. Therefore, the workability of attaching the multi-core optical connector C is good, and the productivity of the optical fiber sheet 100 is high.
