IDF refers to distribution frame. Distribution frame is the most important component in the management subsystem, and it is the hub to realize the cross connection between vertical trunk and horizontal wiring subsystem. Distribution frames are usually installed in cabinets or walls. By installing accessories, the distribution frame can meet the needs of UTP, STP, coaxial cable, optical fiber, audio and video. Twisted pair distribution frame and optical fiber distribution frame are commonly used in network engineering.

Interface devices are hardware devices or component systems that enable users to interact with computers, telephone systems or other electronic information systems.

Extended data

Type of distribution frame:

1, twisted-pair distribution frame

The twisted-pair distribution frame is used to cross-connect the twisted-pair in the management subsystem and is used in the main wiring room and each wiring room.

2. Optical fiber distribution frame

The function of optical fiber distribution frame is to connect the optical cables in the management subsystem, generally between the main wiring room and the distribution line.

3. Intermediate distribution frame

Intermediate distribution frame is a self-supporting or wall-mounted rack, which is used to manage and interconnect long-distance communication cables between user equipment and main distribution frame. MDF includes cables connected to telephone companies or other buildings.
