UNISOL can deliver backbone fiber optic cables designed for harsh environments, these cables resist damage and environmental factors such as rodents chewing on cables. Even with the steel armor, these cables remain flexible and are able to bend randomly. We offer armored cables in any configuration, with any cable modes, and lengths. Outdoor Loose Tube Armored cable has rugged corrugated steel armor which provides extra crush-resistance and rodent protection Suitable for lashed aerial, duct, underground conduit environments. Supported applications include gigabit, 10 gigabit and 40 gigabit Ethernet. The backbone cabling system provides interconnections between telecommunications rooms, equipment rooms, main terminal space, and entrance facilities. It includes backbone cables, intermediate and main cross-connects, mechanical terminations, and patch cords or jumpers used for backbone-to-backbone cross-connections. The backbone also extends between buildings in a campus environment.
