Optical communication cable OKB Ts

Cable with armour made of round steel wires or fiberglass bars designed for laying in soils of all groups, including rocky and subject to permafrost deformations, cable sewers, collectors, bridges, overpasses, river crossings and swamps up to 2 m deep, inside buildings and structures, for aerial suspension (when armoured with GRP bars), in operation from minus 50°? to 60°?.
The outer sheath is made of polymer compositions with consideration of application: at cable entry into the premises from polymer compositions, not spreading burning; in other cases - from polyethylene; round steel wires or fibreglass bars; optical central module.
