The 96-fiber and 72-fiber optical cable cross-connect cabinets (OCCs) are small-to-medium core node devices in fiber access networks, specifically designed for optical network deployment in small-to-medium-sized regions. They provide termination, splicing, storage, and patching functions for 96 fibers and 72 fibers respectively, enabling centralized connection, signal distribution, and flexible scheduling of trunk optical cables and distribution optical cables. As cost-effective solutions for metropolitan area network (MAN) partitioned coverage, enterprise campus networking, and outdoor scattered node interconnection, they fully meet the deployment needs of small-to-medium-scale fiber networks.
