Underground Underwater Gyfty Fiber Optic Cable Crush Resistance Flexibility
Underground Underwater Gyfty Fiber Optic Cable Crush Resistance Flexibility
Description
The fibers, 250μm, are positioned in a loose tube made of PBT, the tubes are filled with a water-resistant filling compound. Loose tubes filled with water proof compound to ensure compact and longitudinally water blocking ,this part of cable accompanied with the steel wires as the supporting part are completed with a polyethylene(PE) sheath to be figure 8 structure.
Characteristics
· High tensile strength of stranded wires meet the requirement of self-supporting
· Good mechanical and temperature performance
· High strength loose tube that is hydrolysis resistant
· Special tube filling compound ensure a critical protection of fiber
· The following measures are taken to ensure the cable watertight:
· Loose tube filling compound
· 100% cable core filling
· steel tape moisture barrier
