24 core fiber optic cable figure8 gytc8s outdoor single mode cables
Description of 24 core fiber optic cable figure8 gytc8s outdoor single mode cables
* Loose tube style, figure-8 optical fiber cable, Jelly compound, optical fiber cable with metallic central strength member of steel wire.
* Filling compound and water-proof tape armored with corrugated steel tape/AL incorporation steel messenger wire suitable for overhead installation as pole to pole or pole to premises.
Features of of 24 core fiber optic cable figure8 gytc8s outdoor single mode cables
* High strength, tracking-resistant sheath.
* GYXTC8S cable is accompanied with the stranded wires as the supporting part to be figure-8 structure.
* 250μm fibers are positioned into a loose tube made of high modulus plastics on the central of cable.
* The tube is filled with a water-resistant filling compound.
* Then the tube is surrounded with aramid yarn to ensure the high tensile strength.
* After that the cable is covered with thin PE (polyethylene) sheath.
