Backbone optical cable connection
A fiber optic backbone network is the central framework of a network that connects multiple sub-networks, systems, and devices using high-capacity fiber optic cables. It serves as the primary pathway for data transmission, linking critical infrastructure such as servers . The building fiber optic backbone requires higher bandwidths at greater distances, connecting the Main Distribution Area (MDA) to all Telecommunications Rooms (TRs)/Interconnect Distribution Frames (IDFs) on each floor. Solutions for fiber-optic cabling based on R&Mfreenet are available either with pre-terminated breakout units, for splice applications or as field termination products. Depending on installation preferences, the right technology choice can be made. -
