GYTZS Loose layer stranded steel-flame retardant sheath optical cable

The optical fiber is set into a high modulus loose tube made of polyester material. The tube is filled with waterproof compounds. The optical fiber has excess length, so that the optical fiber is unstressed. In the center of the cable core, there is a metal reinforced core. Loose tube and the gasket for packing are stranded into a compact circular cable core around the central reinforced core. The gap inside the cable core is filled with water-blocking filler, plastic coated steel band flame-retardant sheath optical cable.
