GYXTW Outdoor Central tube lightly armored optical cable


GYXTW,the fibers, 125μm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape. The cable is completed with a polyethylene (PE) (or low smoke halogen-free flame retardant material) sheath.


Good mechanical and temperature performance

♦ High strength looes tube that is hydrolysis resistant

♦ Special tube filling compound ensure a critical protection of fiber

♦ Crush resistance and flexibility

♦ PSP enhancing moisture-proof

♦ Two parallel steel wires ensure tensile strength

♦ Small diameter, light weight and friendly installation

♦ Long delivery length
