GYFTY53 underground armored fiber optic cable 4 core to 144 core
GYFTY53 fiber optic cable, , 250μm, are positioned in a loose tube made of a high modulus plastics. The tubes are filled with a water-resistant filling compound. A fiber reinforced plastic (FRP) locates in the center of core as a non-metallic strength member. The tubes (and filler) are stranded around the strength member into a compact and circular core. Then the cable core is covered with a thin polyethylene (PE) inner sheath, which is filled with jelly to protect it from water ingress. A layer of water-blocking material is applied around the cable core to prevent water ingress all the same. After a corrugated steel tape armor is applied. the cable is completed with a PE outer sheath. -
GYFTY53 fiber optic cable manufacturers
“GY” refers to Outdoor cable for communication, “F” refers to non-metallic reinforcing member, “T” refers to filled structure, and “Y” refers to polyethylene, “53” means Wrinkled steel strip and Polyethylene sheath. The GYFTY53 cable is constructed by inserting a 250μm fiber into a loose tube made of a high-modulus material filled with a water-repellent compound. The center of the core is a non-metallic reinforcing core (FRP). For some cores, a non-metallic reinforcing core needs to be extruded with a layer of polyethylene (PE).
