The quadruple-network integration optical cable cross-connect cabinet (OCC) is a core node device responding to the policy of co-construction and sharing of communication facilities. Specifically designed to integrate the networks of four major operators—China Telecom, China Mobile, China Unicom, and China Radio and Television (CRTC)—it enables centralized access, signal distribution, cross scheduling, and unified management of trunk optical cables from multiple operators, avoiding duplicate wiring construction. As an efficient solution for "multi-network convergence" in metropolitan area networks (MAN), fiber access networks, and campus structured cabling, it is compatible with multiple capacity specifications ranging from 144 fibers to 1152 fibers, adapting to coverage needs of different scales from small communities to large urban areas.
