4核心单模光学仪户外无装甲光纤电缆/通信电缆

Fiber optic cable , central strength member (steel), jelly filled, fiber contained loose tube and PP filler (if necessary) stranded, water blocking jelly, copolymer coated aluminum tape, PE inner sheath, longitudinally covered by copolymer coated steel tape, PE outer sheath. G652D SM fiber.Detailed specification on your request. Good mechanical and temperature performance,high strength loose tube that is hydrolysis resistant.Special tube filling compound The structure of GYTA is to sheath 250um optical fiber into a loose tube made of high modulus material, and the loose tube is filled with waterproof compound. The center of the cable core is a metal reinforced core. For some fiber optic cables, a layer of polyethylene needs to be squeezed outside the metal reinforced core. The loose tube and the filling rope are twisted around the central reinforcing core to form a compact and circular cable core, and the gaps in the cable core are filled with water blocking fillers. The double-sided plastic-coated steel tape is longitudinally wrapped and then extruded into a cable with a polyethylene sheath.
