Duct Cable is designed to be pulled into ducts in service ducts of an optical cable communication network. Its non-metallic characteristic enables it to be installed in an environment where there is electrical interference, for example alongside power lines. The cable design is available in Unitube loose fibers. The design is lightweight and flexible and able to withstand normal installation forces of strain, crush, bend and twist. Glass yarn can be added for extra axial pulling strength and can be used as protection against rodents. The loose tube containing optical fibers and jelly is centrally placed. Non- metallic strength members (FRP) are embedded in the HDPE sheath for protection and strength.
