Free jumper cable transfer box is widely used in PON technology of FTTx optical access networks, fiber fusion welding, storing, termination, light splitter placement and a cable laying and other functions. No jumper cable transfer box philosophy, effectively solves the defects existing in the traditional optical fiber distribution equipment, reducing fiber adapter and the jumping fiber, reduce communication fault points and insertion loss, enhance network security, increase the capacity of the equipment, easy management and expand the line, reduces the project construction cost, and to promote the development of all-optical networks.
