"The optical cable junction box is a kind of junction equipment that provides optical cable termination and jumper connection for the trunk layer optical cable and the distribution layer optical cable. After the optical cable is introduced into the optical cable junction box, after being fixed, terminated and fiber distribution, the trunk layer is connected with a jumper fiber. The fiber optic cable and the distribution layer fiber optic cable are connected.”
At present, optical fiber communication technology has become the pillar technology of modern communication. The resident optical cable junction box is one of the important symbols of the new-generation information technology revolution in most countries. Optical fiber communication technology has become the main means of transmission of various and complex information in today's information society and has profoundly and extensively changed the overall appearance of the information network architecture. Infinitely bright development prospects. The optical cable transfer box has large communication capacity, long relay distance, no electromagnetic interference, rich resources, light weight, small footprint, and can be installed in different ways. Function of the optical cross box: 1. It divides the trunk optical cable of the communication optical cable into several small logarithmic optical cables in different directions, realizes the jumper connection of the optical cable, and serves as the dividing point of the feeder optical cable and the distribution optical cable, and can also be used for testing and maintenance. 2. Purpose: The optical distribution box is mainly used for the connection, distribution and dispatch of the trunk optical cable and the distribution optical cable in the communication system, power system, traffic control system and cable television system. 3. Structure: The general optical cable junction box is composed of: box body, integrated fusion splice tray, optical cable fixing plate, and fiber hanging column. Fiber optic cable junction box 1.
