Underground Duct GYTA53 GYTY53 Singlemode Fiber Optical Outdoor Cable Direct Buried 36 Fibres DJSA FO Cable
Description:
The fibers, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The cable core is filled with the filling compound to protect it from water ingress, over which a thin PE inner sheath is applied. After the corrugated steel tape is longitudinally applied over the inner sheath, the cable is completed with a PE outer sheath.
GYTY53 fiber optic cable is with steel wire central strength member, corrugated steel tape and double PE sheath. The cable is used for outdoor underground duct/conduit or direct burid. The fiber amount is up to 288 core.
Features:
♦ Excellent mechanical and temperature performance.
♦ Special tube filling compound ensure a critical protection of fiber and resist the water.
♦ Single steel wire as the central strength member to withstand axial loads.
♦ Inner sheath effectively lower the external mechanical loading.
♦ Corrugated steel tape longitudinal cover cable core and provide good crush resistance.
♦ PE sheath protects cable from ultraviolet radiation.
♦ 100% core filling water prevent cable jelly to ensure the cable watertight.
Application:
♦ Direct buried
♦ Underground conduit/duct
♦ Backbone
