GYXTA Cable Structure:
Optical fibers are housed in a high-modulus polyester loose tube filled with waterproof compound. Water-blocking material is applied externally to prevent longitudinal water penetration. The cable is wrapped with steel wires, longitudinally armored with plastic-coated aluminum tape (APL), and sheathed with polyethylene.
