The optical fiber distribution frame (ODF) is used for the termination and distribution of the central trunk optical cable in the optical fiber communication system, and the connection, distribution and scheduling of the optical fiber line can be conveniently realized. With the increasing degree of network integration, a light-number hybrid distribution frame integrating ODF, DDF, and power distribution units has emerged, which is suitable for small to medium-sized distribution of fiber-to-cell, fiber-to-building, remote modules, and wireless base stations. Line system.
