AI Technical Summary
The lack of a reasonable plan for the planning of line protection channels and the arrangement of optical cable connections has led to a waste of screen space resources and inconsistent equipment configurations, failing to meet the principle of modular construction.
Design a fiber optic distribution cabinet that adapts to multiple channel methods. It adopts a vertical partition design, including a DC circuit breaker area, a secondary equipment and terminal block area, a fiber optic distribution area, and a cable routing channel. It is equipped with an independent fiber optic distribution box and protection interface device, supports fiber optic cable connection for multiple channel methods, and adopts a standardized power supply and cabling mode.
It improves screen utilization, reduces screen resource consumption, simplifies construction and maintenance processes, adapts to different configuration scenarios, and reduces the complexity and cost of technical upgrade projects.
