[0002] With the emergence of various new applications such as data centers, big data, and cloud computing, and the continuous increase in the scale of data centers, the networks involved are constantly expanding, and the requirements for the structure of optical fiber cabling are becoming more and more complex. The existing communication optical fiber cables will be distributed disorderly after being connected to the equipment. Especially when there are many communication equipment terminals that need to be installed, the tangled network cables not only affect the appearance, but also bring difficulties to the subsequent inspection and troubleshooting of network faults. Therefore, the requirements for high-density centralized management are getting higher and higher.

[0003] Generally, when used in a fiber optic distribution cabinet, it is necessary to use it with a cable management structure. The cable management structure has the function of organizing and fixing the cables so that the cables are neatly arranged and evenly dissipated. However, existing fiber optic management modules often have a rigid structure, and the cable management structure is an integrated structure or a single-sided detachable structure, which does not have the ability to be completely disassembled. Most cable management structures need to be fixed with bolts in sequence. The product occupies a large space, making it difficult to remove a single strand of cable. The entire module needs to be disassembled during operation, which is inconvenient and affects the convenience of cable maintenance. At the same time, after the fiber density increases, it cannot solve the problems of chaotic fiber patching management and difficulty in subsequent maintenance. In addition, due to the influence of the use environment, the size standard of the cable management rack cannot be absolutely unified, resulting in the emergence of multiple cable management racks. As a result, manufacturers need to build multiple production lines and merchants need to prepare multiple products of different sizes, which increases production costs. Summary of the Invention
