Product Description
GYXTW optical cable consists of single-mode or multi-mode optical fibers housed in a high-modulus PBT (polybutylene terephthalate) loose tube filled with fiber compound. The loose tube is longitudinally wrapped with double-sided aluminum-coated steel tape, with water-blocking materials applied between the steel tape and loose tube to ensure cable compactness and longitudinal water resistance. Two parallel steel wires are placed on both sides, and the whole cable is finished with a polyethylene (PE) outer sheath.
