Description

Technical Field

[0002] Optical cable distribution boxes, as optical fiber connection devices, are distribution and splitting equipment for user terminals in FTTH systems. They can realize functions such as optical fiber splicing, distribution, and scheduling. They can also serve as splitting nodes for long-distance optical fiber transmission. However, existing optical cable distribution boxes mainly have the following shortcomings or technical problems: (1) Insufficient initial capacity planning: In the early stages of network construction in some areas, the forecast of the growth in the number of users was inaccurate, resulting in insufficient port configuration of optical cable distribution boxes. As users' demand for broadband continues to increase, the distribution boxes are prone to quickly reaching their capacity limit, failing to meet the access needs of new users, and requiring frequent capacity expansion operations. (2) Low support and protection performance. For outdoor optical cable distribution boxes, their support performance may gradually decline under harsh environments such as long-term wind and rain.
