In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0044] like Figures 1 to 4 As shown, on one hand, this embodiment provides a fiber optic wiring device, which includes a wiring cabinet 1, an OTN transmission device 2, a fiber combing structure 5 and a fiber fixing structure 6. The OTN transmission device 2 is arranged in the wiring cabinet 1, and a plurality of optical fibers are plugged into the OTN transmission device 2; the fiber combing structure 5 is arranged in the wiring cabinet 1, and the fiber combing structure 5 can comb the optical fibers and set each optical fiber separately at a separation position; the fiber fixing structure 6 is arranged on the OTN transmission device 2, and the fiber fixing structure 6 can clamp and fix the end of each optical fiber.

[0045] By setting up the optical fiber combing structure 5, each optical fiber plugged into the OTN transmission device 2 is separated separately, so as to avoid multiple optical fibers being entangled together and reduce the difficulty of maintenance and replacement; each optical fiber is set separately at the separation position, and there is no need to use a cable bundle or a cable tie for bundling, so as to avoid the large sagging gravity caused by the optical fiber bundling; by setting up the optical fiber fixing structure 6 to clamp and fix the end of the optical fiber, the stability of the connection between the optical fiber end and the OTN transmission device 2 is improved, and the optical fiber is effectively prevented from falling off.

The multiple optical fiber combing structures 5 are arranged in a stepped manner, which means that: from bottom to top along the z direction, the setting heights of the optical fiber combing structures 5 corresponding to the multiple OTN transmission devices 2 gradually increase, and the distance between the OTN transmission device 2 and the corresponding optical fiber combing structure 5 along the y direction gradually increases. Optionally, the multiple optical fiber combing structures 5 are arranged side by side along the y direction, and the distances between two adjacent optical fiber combing structures 5 along the z direction are equal and the distances along the y direction are equal.

[0048] Each optical fiber combing structure 5 can comb and separate multiple optical fibers plugged into an OTN transmission device 2. By setting up multiple optical fiber combing structures 5 in a stepped arrangement, the optical fibers fall downward along the z direction after passing through the optical fiber combing structures 5, so that the optical fibers corresponding to multiple OTN transmission devices 2 can be effectively combed and separated, and the optical fibers corresponding to adjacent OTN transmission devices 2 do not contact each other, and each optical fiber is very convenient to find and take.

The roller is arranged on the wiring cabinet 1, and a plurality of limiting wheels 54 are sleeved on the roller. Two rollers are arranged side by side and spaced apart in the z direction, and the two rollers and the two adjacent limiting wheels 54 on each roller form a separation position.

[0074] By pulling the handle 65 outward, the limit lock block 611 is moved out of the limit lock groove 641, the third elastic member 67 is compressed, and the handle 65 is rotated 90 degrees, so that the card plate 62 is rotated to between two adjacent optical fiber sockets 22 of the OTN transmission device 2, and the card plate 62 is attached to the outer surface of the optical fiber socket 22; the handle 65 is released, and under the action of the third elastic member 67, the C-shaped notch of the card plate 62 can clamp and press against the end of the optical fiber, and at the same time, the limit lock block 611 is inserted into the limit lock groove 641, so as to prevent the rotating shaft 61 from rotating, thereby preventing the end of the optical fiber from falling off from the optical fiber socket 22.

[0075] In this embodiment, the third elastic member 67 and the first elastic member 45 can both be springs; the second elastic member 59 can be a memory spring.

[0076] Another aspect of the present embodiment provides an optical fiber wiring method, which uses the above optical fiber wiring device to perform wiring, including the following steps:

[0077] Step S1 , plug the head end of the optical fiber into the OTN transmission device 2 , guide the optical fiber close to the optical fiber combing structure 5 and set each optical fiber individually at the separation position of the optical fiber combing structure 5 .

[0078] When using the optical fiber distribution device, the sliding member 41 is controlled to slide downward in the slide groove 112 along the z direction, and the sliding member 41 drives the end of the traction member 42 to move downward. The first fixed pulley 44 and the second fixed pulley 46 are used to change the traction direction of the traction member 42, thereby pulling the positioning member 43 to move along the x direction, thereby driving the positioning protrusion 432 to shrink into the connecting hole of the wiring cabinet 1, and the first elastic member 45 is compressed at this time.

[0079] At this time, the OTN transmission device 2 is fully inserted into the storage slot 111 of the wiring cabinet 1, and the sliding member 41 is released. Under the action of the first elastic member 45, the positioning protrusion 432 moves along the x direction and is pushed outward, so that the positioning protrusion 432 is inserted into the positioning hole 21 of the OTN transmission device 2, thereby fixing the OTN transmission device 2 in the wiring cabinet 1.

[0080] Next, the head end of the optical fiber is plugged into the optical fiber socket 22 of the OTN transmission device 2, and then the optical fiber is passed through the wiring box 3, and the end of the optical fiber is passed into the optical fiber storage slot 113 of the wiring cabinet 1, so that the optical fiber is placed on the support roller 52 of the optical fiber combing structure 5, and multiple optical fiber combing structures 5 arranged in a stepped manner are used to separately store the optical fibers connected to the OTN transmission devices 2 at different heights.

[0081] The specific operation process of the optical fiber combing structure 5 is as follows: by pulling the handle 58 outward, the T-shaped shaft 55 moves toward the outside of the cabinet 11 along the x direction, at this time, the T-shaped shaft 55 partially extends from the clamping roller 53 and the second elastic member 59 is compressed, and the fixing pin 57 is separated from the support roller 52; the clamping roller 53 is controlled to move upward along the z direction by the handle 58, and the distance between the clamping roller 53 and the support roller 52 is increased, so that the optical fiber can be placed between the clamping roller 53 and the support roller 52; the clamping roller 53 is controlled to move upward along the z direction by the handle 58, and the distance between the clamping roller 53 and the support roller 52 is increased, so that the optical fiber can be placed between the clamping roller 53 and the support roller 52. The clamping roller 53 and the supporting roller 52 are moved downward in the direction of rotation, and the clamping roller 53 and the supporting roller 52 are brought close to each other. Then the clamping roller 53 is rotated, and each group of optical fibers is separated independently by using the supporting roller 52 and the limiting wheel 54 on the clamping roller 53. After the optical fiber combing is completed, the handle 58 is released, and under the action of the second elastic member 59, the T-shaped shaft 55 moves and resets along the x direction toward the inside of the cabinet 11, and drives the fixing pin 57 to be inserted into the supporting roller 52 through the connecting plate 56, so that the supporting roller 52, the clamping roller 53 and the limiting wheel 54 can keep the clamped and limited optical fiber.

[0082] Step S2: clamp and fix the head end of the optical fiber on the OTN transmission device 2 through the optical fiber fixing structure 6.

[0083] The specific operation process of the optical fiber fixing structure 6 is as follows: by pulling the handle 65 outward, the limiting lock block 611 is moved out of the limiting lock groove 641, the third elastic member 67 is compressed, and the handle 65 is rotated 90 degrees, so that the card plate 62 is rotated to between two adjacent optical fiber sockets 22 of the OTN transmission device 2, and the card plate 62 is attached to the outer surface of the optical fiber socket 22; the handle 65 is released, and under the action of the third elastic member 67, the C-shaped notch of the card plate 62 can clamp and press against the end of the optical fiber, and at the same time, the limiting lock block 611 is inserted into the limiting lock groove 641, so as to prevent the rotating shaft 61 from rotating, thereby preventing the end of the optical fiber from falling off from the optical fiber socket 22.

[0084] By using a fiber optic wiring device for wiring, each optical fiber can be set up separately, avoiding the entanglement of optical fibers, helping to accurately connect the interface of the optical fiber and the OTN transmission device 2, reducing the difficulty of optical fiber management and maintenance, and also helping to ensure the spacing between optical fibers and thereby increase the signal transmission rate.

For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
