Summary of Invention

Problems to be Solved by the Invention

[0004] When a plurality of sheets are bonded together to hold the wiring of optical fibers, various problems arise. For example, air may enter between the sheets, and this air expands or contracts due to temperature changes, which may cause lateral pressure to act on the optical fibers. Alternatively, at locations where optical fibers intersect each other, the optical fibers may be pressed by the sheets, causing local bending or lateral pressure to act thereon. Such lateral pressure or bending may cause an increase in transmission loss or disconnection in the optical fibers. In addition, when the wiring is complex, it is difficult to perform work on a flat surface, and further, it is also difficult to bond the sheets together while maintaining the wired state.

[Figure 7] This is a perspective view of the optical wiring device according to this embodiment. [Figure 8] Figure 7 shows the optical wiring device with the device cover removed. [Modes for carrying out the invention]

[0015] <Optical wiring components> The optical wiring components of this embodiment will be described below with reference to the drawings. As shown in Figure 1, the optical wiring component 1 has an inlet portion 10 and an outlet portion 20. The inlet portion 10 is provided with a first inlet hole group 11, a second inlet hole group 12, a third inlet hole group 13, and a fourth inlet hole group 14. Each of the inlet hole groups 11 to 14 includes a plurality of inlet holes. For example, the first inlet hole group 11 includes eight inlet holes 11a to 11h. Similarly, each of the inlet hole groups 12 to 14 also includes eight inlet holes. Note that the number of inlet hole groups provided in the inlet portion 10 is not limited to four and can be changed. In addition, the number of inlet holes included in each inlet hole group is not limited to eight and can be changed.

[0016] The outlet portion 20 is provided with a plurality of outlet holes 21 to 28. In the present embodiment, the number of outlet holes is eight. The number of outlet holes provided in the outlet portion 20 is not limited to eight and can be changed. The number of outlet holes provided in the outlet portion 20 is less than the total number of inlet holes provided in the inlet portion 10.

[0017] <Direction Definition> In the optical wiring component 1, the direction in which the inlet portion 10 and the outlet portion 20 are arranged is referred to as the longitudinal direction Z. In the longitudinal direction Z, the direction from the inlet portion 10 toward the outlet portion 20 (+Z side) is referred to as the downstream side, and the direction from the outlet portion 20 toward the inlet portion 10 (-Z side) is referred to as the upstream side. Further, in the inlet portion 10, the direction in which the plurality of inlet hole groups 11 to 14 are arranged is referred to as the parallel direction X. One side in the parallel direction X is referred to as the -X side, and the other side is referred to as the +X side. The direction orthogonal to both the longitudinal direction Z and the parallel direction X is referred to as the orthogonal direction Y. One side in the orthogonal direction Y is referred to as the -Y side, and the other side is referred to as the +Y side.

[0018] The optical wiring component 1 of the present embodiment has a structure in which a plurality of tubular wiring paths are formed inside a block body B. In the example of Figure 1, the block body B has a rectangular parallelepiped shape. More specifically, the block body B has a first end face facing the upstream side (-Z side) and a second end face facing the downstream side (+Z side). The first end face functions as an inlet portion 10, and the second end face functions as an outlet portion 20. The block body B also has end faces facing the -X side, +X side, -Y side, and +Y side respectively. That is, the block body B has a total of six end faces. However, the shape of the block body B can be modified. Furthermore, the optical wiring component 1 may, instead of the block body B, have a structure in which, for example, a plurality of tubes are combined.

[0019] The optical wiring component 1 has a structure in which wiring paths extending downstream from a plurality of inlet holes merge inside the optical wiring component 1 and are connected to an outlet hole. In this way, the portion where the wiring paths merge is referred to as a "merging portion J". A plurality of merging portions J are provided inside the optical wiring component 1. For example, attention is focused on the inlet hole 11d of the first inlet hole group 11, the inlet hole 12d of the second inlet hole group 12, the inlet hole 13d of the third inlet hole group 13, and the inlet hole 14d of the fourth inlet hole group, which are shown in Figure 1. Wiring paths P11, P12, P13, and P14 extend downstream from these inlet holes 11d, 12d, 13d, and 14d respectively. These wiring paths P11, P12, P13, and P14 merge at a merging portion J existing inside the optical wiring component 1. This merging portion J and the outlet hole 21 are connected by a wiring path P1. From the downstream side toward the upstream side, the inlet hole groups 11 to 14, the merging portion J, and the outlet holes 21 to 28 are arranged in this order.

[0020] Focusing on the outlet hole 21, the inlet holes 11d, 12d, 13d, and 14d included in the four inlet hole groups 11 to 14 are connected one by one. Similarly, for the outlet holes 22 to 28, the inlet holes included in the four inlet hole groups 11 to 14 are connected one by one. That is, for all of the outlet holes 21 to 28, the inlet holes included in the inlet hole groups 11 to 14 are connected one by one. Therefore, in the case of the present embodiment, the number of inlet holes is four times the number of outlet holes. Specifically, the total number of inlet holes is 32, and the number of outlet holes is 8.

[0021] Figure 2 is a view of the inlet section 10 in Figure 1, seen from the direction of arrow II. As shown in Figure 2, focusing on the first inlet hole group 11, the eight inlet holes 11a to 11h are arranged in a 2x4 two-dimensional pattern. Specifically, four inlet holes 11a to 11d are arranged in a row in the orthogonal direction Y. Also, four inlet holes 11e to 11h are arranged in a row in the orthogonal direction Y. The row formed by inlet holes 11a to 11d and the row formed by inlet holes 11e to 11h are arranged in the parallel direction X. Similarly, in the other inlet hole groups 12 to 14, the inlet holes are each arranged in a 2x4 two-dimensional pattern.

[0022] Figure 3 is a view of the outlet section 20 in Figure 1, seen from the direction of arrow III. As shown in Figure 3, the outlet holes 21 to 24 are located at different positions in the parallel direction X and the orthogonal direction Y. Similarly, the outlet holes 25 to 28 are located at different positions in the parallel direction X and the orthogonal direction Y. By making the positions of adjacent outlet holes different in the parallel direction X and the orthogonal direction Y in this way, interference between the wiring paths connected to each outlet hole can be avoided.

[0023] However, the arrangement of the inlet hole groups 11-14 and outlet holes 21-28 shown in Figures 2 and 3 is merely an example and may be changed as appropriate. Also, in this embodiment, each of the four inlet hole groups 11-14 is connected to each of the outlet holes 21-28. However, the correspondence between inlet holes and outlet holes can be changed. For example, there may be junctions and outlet holes to which only some of the four inlet hole groups 11-14 are connected. More specifically, there may be junctions and outlet holes connected to only one inlet hole group.

[0024] <Optical Wiring Unit> Figure 4 is a schematic diagram of an optical wiring unit 2 using an optical wiring component 1. The optical wiring unit 2 comprises an optical wiring component 1, a plurality of upstream connectors C11 to C14, a plurality of downstream connectors C21 to C24, and a plurality of optical fibers F. The upstream connectors C11 to C14 correspond to the inlet hole groups 11 to 14 of the optical wiring component 1. Specifically, the optical fiber F of the first upstream connector C11 is introduced into the optical wiring component 1 through the inlet holes 11a to 11h included in the first inlet hole group 11. Similarly, the optical fibers F of the second upstream connector C12, the third upstream connector C13, and the fourth upstream connector C14 are introduced into the optical wiring component 1 from the inlet holes of the second inlet hole group 12, the third inlet hole group 13, and the fourth inlet hole group 14, respectively.

[0025] As shown in Figure 2, the first inlet hole group 11, the second inlet hole group 12, the third inlet hole group 13, and the fourth inlet hole group 14 are arranged in that order from the -X side to the +X side. Correspondingly, as shown in Figure 4, the first upstream connector C11, the second upstream connector C12, the third upstream connector C13, and the fourth upstream connector C14 are arranged in that order from the -X side to the +X side.

[0026] The first downstream connector C21 is connected to the optical fiber F extending from the exit holes 21 and 22 to the outside of the optical wiring component 1. The second downstream connector C22 is connected to the optical fiber F extending from the exit holes 23 and 24 to the outside of the optical wiring component 1. The third downstream connector C23 is connected to the optical fiber F extending from the exit holes 25 and 26 to the outside of the optical wiring component 1. The fourth downstream connector C24 is connected to the optical fiber F extending from the exit holes 27 and 28 to the outside of the optical wiring component 1.

[0027] The wiring paths of the optical fibers F will be explained using Figures 4 and 1. First, let's focus on the first upstream connector C11 shown in Figure 4. Multiple optical fibers F of the first upstream connector C11 are inserted into the inlet holes 11a to 11h included in the first inlet hole group 11. The optical fibers F inserted into inlet holes 11a to 11d each travel through independent wiring paths within the optical wiring component 1 and reach the exit holes 21 to 24, respectively. These optical fibers F are then connected to the first downstream connector C21 and the second downstream connector C22 downstream of the exit holes 21 to 24. The optical fibers F inserted into inlet holes 11e to 11h each travel through independent wiring paths within the optical wiring component 1 and reach the exit holes 25 to 28, respectively. These optical fibers F are then connected to the third downstream connector C23 and the fourth downstream connector C24 downstream of the exit holes 25 to 28.

[0028] Furthermore, the inlet holes 11d, 12d, 13d, and 14d are connected to the outlet hole 21. In other words, the optical fibers F contained in each of the four upstream connectors C11 to C14 are connected to one downstream connector C21 through one outlet hole 21. The same applies to the other outlet holes 22 to 28. In this way, the optical wiring component 1 is configured to connect the optical fibers F of multiple upstream connectors to one downstream connector.

[0029] As an example, optical fiber F constitutes a two-core ribbon cable. Eight ribbon cables are connected to the upstream connectors C11-C14 and the downstream connectors C21-C24. In this case, a total of 16 optical fibers F are connected to the upstream connectors C11-C14 and the downstream connectors C21-C22. In this case, the upstream connectors C11-C14 and the downstream connectors C21-C22 may have 16-core ferrules. In this example, one ribbon cable (i.e., two optical fibers F) is inserted into one inlet hole. Also, four ribbon cables extend from each outlet hole. The downstream connectors C21-C24 each connect to eight ribbon cables (i.e., a total of 16 optical fibers F) extending from two outlet holes.

[0030] As described above, multiple optical fibers F may be inserted into a single inlet hole. Alternatively, only one optical fiber F may be inserted into a single inlet hole. Furthermore, the number of optical fibers F connected to the upstream connectors C11~C14 and the downstream connectors C21~C24 can be changed as appropriate.

[0031] As shown in Figure 1, the wiring path of the optical fiber F provided within the optical wiring component 1 includes a curved section. Therefore, when the optical fiber F is inserted into the optical wiring component 1, multiple optical fibers F are bent along the curved section of the wiring path. Here, the radius of curvature at the curved section of the wiring path within the optical wiring component 1 is set to be larger than the allowable bending radius of the optical fiber F. Therefore, bending of the optical fiber F at a radius smaller than the allowable bending radius within the optical wiring component 1 is suppressed. In addition, because the wiring path within the optical wiring component 1 is smoothly curved, jamming of the optical fiber F in the curved section during manufacturing is suppressed.

[0032] In this embodiment, the optical wiring unit 2 is equipped with upstream connectors C11-C14 and downstream connectors C21-C24, but the optical wiring unit 2 does not necessarily have to be equipped with such connectors. For example, the optical wiring unit 2 may be shipped without connectors, and the connectors may be attached to the optical fiber F at the optical wiring installation site. Alternatively, other optical equipment may be connected to the end of the optical fiber F in the optical wiring unit 2 instead of a connector.

[0033] <Method of wiring optical fibers> Next, a method for wiring optical fibers using optical wiring component 1 will be described. First, prepare optical wiring component 1 and multiple optical fibers F. At this point, upstream connectors C11 to C14 may be connected to one end of each of the multiple optical fibers F. Also, the optical fibers F may form a ribbon fiber.

[0034] Next, multiple optical fibers F are inserted into the optical wiring component 1 through each of the inlet holes 11 to 14. The multiple optical fibers F travel downstream along the wiring path within the optical wiring component 1. Multiple merging sections J are provided inside the optical wiring component 1. At these merging sections J, the optical fibers F inserted from each of the inlet holes 11 to 14 merge. Furthermore, exit holes 21 to 28 are located downstream of each merging section J. Therefore, the optical fibers F that merge at the merging section J extend out from the corresponding exit holes 21 to 28.

[0035] Next, the optical fibers F extending downstream from the exit holes 21 to 28 are connected to the downstream connectors C21 to C24. At this time, the optical fibers F extending from the exit holes 21 to 28 may be fusion spliced ​​to the optical fibers already provided in the downstream connectors C21 to C24. Alternatively, the optical fibers F extending from the exit holes 21 to 28 may be assembled to each ferrule of the downstream connectors C21 to C24.

[0036] As a result, as shown in Figure 4, multiple upstream connectors C11-C14 and multiple downstream connectors C21-C24 are connected. At this time, the optical fiber F is naturally shuffled three-dimensionally within the optical wiring component 1. Shuffled wiring is a wiring configuration in which multiple optical connectors are connected to one optical connector. The optical fiber F or ribbon fiber may be colored to identify it. In this case, it is easy to identify which of the upstream connectors C11-C14 the optical fiber F extending from the exit holes 21-28 belongs to. Alternatively, by combining coloring with ring marks or the like, it may be possible to identify which number the optical fiber F or ribbon fiber is within a single upstream connector.

[0037] <Optical wiring module> Next, an optical wiring module 100 equipped with optical wiring component 1 will be described using Figures 5 and 6. As shown in Figures 5 and 6, the optical wiring module 100 comprises a housing 100a, optical wiring component 1, a plurality of optical fibers F, upstream connectors C11 and C12, downstream connectors C21 and 22, upstream adapters A11 and A12, and downstream adapters A21 and A22. In this example, there are two upstream connectors C11 and C12 and two downstream connectors C21 and 22, but as shown in Figure 4, the number of upstream and downstream connectors may be four, three, or five or more. Upstream adapters A11 and A12 are connected to upstream connectors C11 and C12. Downstream adapters A21 and A22 are connected to downstream connectors C21 and C22.

[0038] The optical wiring component 1, multiple optical fibers F, upstream connectors C11 and C12, and downstream connectors C21 and C22 are housed inside the housing 100a. In other words, the optical wiring unit 2 is housed inside the housing 100a. The housing 100a is rectangular in shape as a whole. The housing 100a is composed of two parts: a module cover 110 and a module housing body 120. The module housing body 120 is box-shaped with an opening, which is closed by the module cover 110. The module cover 110 and the module housing body 120 may be fixed together, for example, with screws. By removing the module cover 110, the optical wiring unit 2 housed in the module housing body 120 is exposed. However, the configuration of the housing 100a can be changed as appropriate.

[0039] The module housing body 120 has an upstream side wall 121 and a downstream side wall 122. The upstream side wall 121 supports the upstream adapters A11 and A12. The downstream side wall 122 supports the downstream adapters A21 and A22. A space S is provided inside the housing 100a that is not occupied by the optical wiring components 1. The space S may be used, for example, to accommodate the excess length of the optical fiber F. Note that the optical fiber F is partially omitted from the illustration in Figure 6. In the space S, the excess length of the optical fiber F may be wound in a loop shape, for example.

[0040] The optical wiring component 1 is fixed inside the housing 100a. The means of fixing are not particularly limited, but for example, screw fastening, adhesive bonding, etc., can be applied. Similarly, the excess length portion of the optical fiber F may also be fixed inside the housing 100a.

[0041] With this optical wiring module 100, the shuffled wiring portion or excess length portion of the optical fiber F can be protected by the housing 100a. Therefore, disconnections of the optical fiber F can be suppressed. Furthermore, as shown in Figure 5, the housing 100a is provided with mounting holes 121a for installing the optical wiring module 100 on the object to be installed. Using these mounting holes 121a, the optical wiring module 100 can be easily installed on the object to be installed.

[0042] <Optical Wiring Devices> Next, an optical wiring device 200 equipped with optical wiring modules 100 will be described using Figures 7 and 8. The optical wiring device 200 has a device housing 210 and a device cover 220. As shown in Figure 8, when the device cover 220 is removed, the inside of the device housing 210 is exposed. Four optical wiring modules 100 are housed inside the device housing 210. The number of optical wiring modules 100 can be changed as appropriate.

[0043] As shown in Figure 7, the device housing 210 is provided with device mounting holes 211 for installing the optical wiring device 200 on the object to be installed. With the optical wiring device 200, multiple optical wiring modules 100 can be easily installed on the object to be installed.

[0044] As described above, the optical wiring component 1 of this embodiment comprises an inlet section 10 having a plurality of inlet hole groups 11 to 14, and an outlet section 20 having a plurality of outlet holes 21 to 28. Each of the plurality of inlet hole groups 11 to 14 contains a plurality of inlet holes, and each of the plurality of outlet holes 21 to 28 is connected to a merging section J. The merging section J is connected to the plurality of inlet holes.

[0045] Furthermore, the optical wiring unit 2 of this embodiment comprises an optical wiring component 1 and a plurality of optical fibers F inserted from a plurality of inlet holes in a plurality of inlet hole groups 11 to 14 to a plurality of outlet holes 21 to 28.

[0046] Furthermore, the optical fiber wiring method of this embodiment includes a preparation step, an insertion step, a merging step, and an extension step. In the preparation step, an optical wiring component 1 having a plurality of inlet hole groups 11 to 14 and a plurality of outlet holes 21 to 28, and a plurality of optical fibers F are prepared. In the insertion step, the plurality of optical fibers F are inserted into the optical wiring component 1 through the plurality of inlet holes each included in the plurality of inlet hole groups 11 to 14. In the merging step, the plurality of optical fibers F inserted from the plurality of inlet holes are merged at the merging section J inside the optical wiring component 1. In the extension step, the plurality of optical fibers merged at the merging section J are extended from the outlet hole located downstream of the merging section J.

[0047] With such optical wiring components 1, optical wiring units 2, or wiring methods, multiple optical fibers F can be easily shuffled and maintained by inserting them into the entrance holes included in the entrance hole groups 11-14. This solves various problems that arise when maintaining the wiring state by bonding multiple sheets together, as in the conventional method. For example, air does not get trapped between the sheets and expand or contract due to temperature changes. Therefore, lateral pressure acting on the optical fibers can be suppressed. Alternatively, local bending or lateral pressure acting on the optical fibers pressed by the sheets at points where optical fibers intersect can be suppressed. Therefore, an increase in transmission loss or disconnection in the optical fibers can be suppressed. Furthermore, even when the wiring is three-dimensionally complex, wiring can be achieved by inserting the optical fibers F into the entrance holes, thus improving manufacturing efficiency.

[0048] Furthermore, the radius of curvature of the bend in the wiring path from the multiple inlet holes in the multiple inlet hole groups 11 to 14 to the multiple outlet holes 21 to 28 may be larger than the allowable bending radius of the multiple optical fibers F. In this case, it is possible to suppress the bending of the optical fibers F within the optical wiring component 1 at a radius smaller than the allowable bending radius. Therefore, it is possible to suppress an increase in transmission loss, etc.

[0049] Furthermore, the optical wiring unit 2 may include a plurality of upstream connectors C11 to C14 connected to a plurality of optical fibers F extending upstream from a plurality of inlet holes in a plurality of inlet hole groups 11 to 14, and a plurality of downstream connectors C21 to C24 connected to a plurality of optical fibers F extending downstream from a plurality of outlet holes 21 to 28. In this case, the optical fibers F can be shuffled between the upstream connectors C11 to C14 and the downstream connectors C21 to C24.

[0050] Furthermore, the optical wiring module 100 of this embodiment comprises an optical wiring unit 2, a plurality of upstream adapters A11, A12 to which a plurality of upstream connectors C11, C12 are connected, a plurality of downstream adapters A21, A22 to which a plurality of downstream connectors C21, C22 are connected, and a housing 100a that supports the plurality of upstream adapters A11, A12 and the plurality of downstream adapters A21, A22. With this optical wiring module 100, shuffle wiring can be easily performed by connecting other optical devices to the upstream adapters A11, A12 and the downstream adapters A21, A22, respectively.

[0051] Furthermore, the optical wiring unit 2 of this embodiment includes a block body B having a first end face as an inlet portion 10 and a second end face as an outlet portion 20, and multiple tubular wiring paths connecting multiple inlet hole groups 11 to 14 and multiple outlet holes 21 to 28 are formed inside the block body B. With this configuration, the optical wiring unit 2 can be easily manufactured. The material of the block body B may be, for example, resin. Also, the block body B may be molded by a 3D printer.

[0052] The technical scope of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.

[0053] For example, in the above embodiment, the optical wiring module 100 or optical wiring device 200 was described as being attached to the object to be installed using the mounting hole 121a of the optical wiring module 100 or the device mounting hole 211 of the optical wiring device 200. However, the optical wiring component 1 itself may have mounting holes, etc., for attachment to the object to be installed. Also, when using the optical wiring unit 2, it does not have to be in the form of an optical wiring module 100 or optical wiring device 200.

[0054] Furthermore, without departing from the spirit of the present invention, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described embodiments and modifications may be combined as appropriate.
