Optical distribution frame (ODF) for optical fiber communication system into the trunk cable midgame, and can be easily realized fiber-optic links, distribution and scheduling. With the increasingly high degree of integration, network, appeared set ODF, power distribution unit, DDF to light, suitable for mixing distribution frame, optical fiber to the village to building, remote module bureau and wireless stations and wiring system.

Distribution frame are among the most important management subsystem, the main component is vertical and horizontal wiring two subsystem cross-connections hub. Distribution frame is normally installed in cabinet or wall. By installing the accessories, distribution frame can all meet UTP, STP, coaxial cable, optical fiber, audio and video. In the network project in distribution frame are twisted-pair cable distribution frame and fiber distribution frame. Twisted-pair cable distribution frame is in the management subsystem cross connection will twisted-pair wiring in the Lord, and the distribution line. Twisted-pair cable distribution frame, each type of many manufacturers have their own product series, and the corresponding class 3, 5, 6, 5 kinds of super and 7 class cable respectively have different specifications and types, in the practical project, and shall refer to the product manual, according to the actual situation of configuration.
Optical distribution frame is in the management subsystem, usually will connect cable in the wiring and various distribution line.
