Description

Technical Field

[0001] The utility model relates to the technical field of optical cross-connect boxes, in particular to an optical cross-connect box with a wire management structure. Background Art

[0002] As one of the main forms of modern communication, the stability and transmission speed of optical fiber communication have a decisive influence on the communication quality. In the optical fiber communication system, the optical cross-connect box, as an important connection and distribution equipment, undertakes the functions of optical fiber access, distribution, scheduling and management. With the rapid development of optical fiber networks, the design and functions of the optical cross-connect box are also constantly optimized and upgraded to meet the needs of more efficient and stable networks.

[0003] However, when there are a large number of optical cables, the optical fibers are prone to entanglement, which not only affects the appearance, but more importantly, may cause damage to the optical fibers, increase the difficulty and cost of maintenance. In addition, the chaotic layout of the optical fibers in the optical cross-connect box will also affect the heat dissipation performance of the optical fibers, thereby affecting the stability and service life of the entire optical fiber system. The usual method is to set a cylinder inside the box and wrap the excess optical cable bundles around its outside. Although this method can reduce the entanglement between optical cables, it causes the optical cables to be bent multiple times, which can easily cause damage to the internal wires. For this reason, an optical cross-connect box with a wire management structure is needed to solve the existing deficiencies. Utility Model Content
