Stranded Loose Tube Non-armored Cable GYTY
GYTY optic fiber cable is with single-mode or multimode structure ,optical fibers are jacketed waterproof compound filled loose tube made of high modulus plastic tube. The center of the cable core is a metal strengthening core for a ce ain number of cores for the optical fiber cable, metal strengthen squeeze packet layer of polyethylene (PE) in addition to the core. Loose tube (filling cord) around the center to strengthen core twisted into a compact and circular cable core, the core is filled with water blocking compound, PE sheathed cabling.
Features
Good mechanical and temperature performance High strength loose tube that is hydrolysis resistant Special tube filling compound ensure a critical protection of fiber Crush resistance and flexibility PE sheath protects cable from ultraviolet radiation Operating temperature:-30~+70℃; storage temperature:-40~+70℃
