π Part Number Definition
GY β Outdoor optical cable for communication field or equipment room
X β Central tube (or core) structure
T β Filled structure
W β Steel-polyethylene bonded sheath with steel wire reinforcement (W sheath)
π Product Overview
This cable is developed and manufactured by Jiqian Fiber Optic Cable, a company specialized in researching and producing high-performance fiber optic solutions. It uses a central loose tube to securely house 250β―ΞΌm fibers in high-modulus plastic, filled with a water-blocking compound. A longitudinally applied PSP (steel-plastic composite tape) provides added protection, with water-blocking layers between the PSP and loose tube ensuring a compact, watertight structure. Two parallel steel wires strengthen the cable on both sides, and a polyethylene (PE) outer sheath completes the robust build.
