They are suitable for small and medium-sized wiring systems for fiber to the community, fiber to the building, remote modules and wireless base stations.

[0003] Traditional fiber optic distribution frames commonly suffer from the following technical drawbacks in communications applications: 1. Most existing patch panel backplanes are fixed structures with separate 19-inch subframes from the backplane. When expanding capacity or replacing modules, the entire frame needs to be disassembled, which is cumbersome and inefficient, making it difficult to meet the needs of rapid deployment in high-density data centers.
