Description

Technical Field

[0001] The present invention relates to the field of optical fiber management technology, and in particular to an intelligent optical fiber wiring method and system based on relay technology. Background Art

[0002] Fiber optic wiring refers to the process of connecting and distributing optical fibers according to certain rules and standards. In the past, manual fiber optic wiring often faced two major problems: fiber entanglement and high labor costs. To solve these problems, the industry has invented a series of intelligent fiber optic wiring systems, among which beam steering technology and electromechanical technology are the most common. When the power is off in the computer room, the intelligent fiber optic wiring system based on beam steering technology will cause the light connection to be interrupted. Although the intelligent fiber optic wiring system based on electromechanical technology can maintain connection during power outages, its connector is completely incompatible with the existing fiber optic wiring frame, and the cost of transformation is unacceptable. In addition, the design is complex, there are many fault points, maintenance is difficult, and the scale of connection is also very limited. For example, the automatic fiber management system AFM (Automated Fiber Management) released by Fiberzone-Network in 2006 adopts a vertical and horizontal switching method. In order to increase the capacity of the system, a customized thin-film fiber optic connector is used. This solution is small in size and easy to carry, but because the capacity cannot be increased and the manufacturer is weak in follow-up, it has now withdrawn from use. Summary of the invention

[0003] The present invention proposes an intelligent optical fiber wiring method and system based on relay technology. In order to overcome the problems of the prior art, the present invention welds an L-shaped wire management column on the basis of the existing optical fiber distribution frame, so that the jumper optical fiber line bypasses the L-shaped wire management column instead of drooping naturally, which is convenient for distinguishing the inner and outer areas of the jumper while making the jumper more orderly. The tangle-free jumper planning method of the present invention connects the edge features of the jumper optical fiber line and the connection between the starting port and the target port of the jumper optical fiber line and regards them as a closed loop, and then prohibits the subsequent jumper optical fiber line from passing through the inside of the closed loop, so that the subsequent jumper optical fiber line and the previous jumper optical fiber line form a homeomorphic topological relationship, which prevents the jumper from being tangled. The technical effect of the optical fiber lines being entangled with each other, the present invention also includes using the minimum loss virtual path method to find all potential optical fiber paths through the breadth-first search method when a fiber optic relay network fails, and using the tangle-free jumper planning method to plan the jumper routes for all jumpers of all potential optical fiber paths one by one to predict the non-intrinsic optical fiber loss caused by the jumper, and finally calculating the expected optical fiber loss of all potential optical fiber paths through a multi-layer perceptron and selecting the one with the least expected optical fiber loss as the new path with the lowest loss. The present invention is based on topology and realizes economical, intelligent, and tangle-proof intelligent optical fiber wiring by adding a mechanical arm and simple and effective optical fiber distribution frame transformation.

[0041] The beneficial effects achieved by the present invention using the above scheme are as follows:

[0042] (1) The present invention welds an L-shaped cable management column on the basis of the existing optical fiber distribution frame, so that the jumper optical fiber line bypasses the L-shaped cable management column instead of hanging naturally, which facilitates the distinction between the inner and outer areas of the jumper and makes the jumper more orderly. The tangle-free jumper planning method of the present invention connects the edge features of the jumper optical fiber line and the connection between the starting port and the target port of the jumper optical fiber line and regards them as a closed loop, and then prohibits the subsequent jumper optical fiber line from passing through the closed loop, so that the subsequent jumper optical fiber line and the previous jumper optical fiber line form a homeomorphic topological relationship, which plays a technical effect of preventing the jumper optical fiber lines from being entangled with each other. The invention also includes using a minimum loss virtual path method to search all potential optical fiber paths through a breadth-first search method when a fiber optic relay network fails, and using a tangle-free jumper planning method to plan jumper routes for all jumpers of all potential optical fiber paths one by one to predict the non-intrinsic optical fiber loss caused by the jumpers, and finally calculating the expected optical fiber loss of all potential optical fiber paths through a multi-layer perceptron and selecting the one with the least expected optical fiber loss as the new path with the lowest loss. The invention is based on topology and realizes economical, intelligent, and tangle-free intelligent optical fiber distribution by adding a mechanical arm and simply and effectively transforming the optical fiber distribution frame.

[0043] (2) The minimum loss virtual path method proposed in the present invention uses the number of nodes passed by the optical fiber path and the total curvature of the jumper optical fiber line to characterize the non-intrinsic optical fiber loss caused by docking and bending, and uses the total length of the optical cable and the total length of the jumper optical fiber line in the optical fiber path to characterize the intrinsic loss inherent in the optical fiber material. This targeted feature engineering introduces prior knowledge of optics and materials science, and effectively improves the prediction performance of the multilayer perceptron for expected optical fiber loss. Different from simply using the multilayer perceptron, the minimum loss virtual path method uses the tangle-free jumper planning method to estimate the total curvature and total length of the jumper optical fiber line, which effectively fits the optical fiber loss caused by the jumper optical fiber line in the actual jumper process, and realizes the minimum loss new path selection combining machine learning and physical simulation.

[0044] (3) The difference between the intelligent fiber optic wiring system based on relay technology proposed in the present invention and the existing automated fiber optic management system is that the existing automated fiber optic management system adopts electromechanical or optical structures that are not compatible with the existing fiber optic distribution frame to prevent the fiber optic entanglement problem, while the intelligent fiber optic wiring system based on relay technology proposed in the present invention only needs to weld L-shaped cable management poles on the existing fiber optic distribution frame and install a robotic arm in the machine room. It has significant economic advantages. The fault points are concentrated on the robotic arm, which is also convenient for maintenance personnel to check. Even when the robotic arm fails, it can still support manual jumpering and has high scalability, which is impossible for the existing automated fiber optic management system.
