Unitube (Central Loose) Outdoor Cable GYXTW

GYXTW (metal strengthening member, steel-polyethylene bonded sheath with steel wire entrained, central beam tube type full-filled outdoor optical cable for communication) The structure of the optical cable is to place the loose tube in the center of the cable, and the single-mode optical fiber is sheathed by the A loose tube made of high modulus plastic filled with waterproof compound. The loose tube is longitudinally wrapped with water-blocking tape and steel belt, and the two sides of the cable core are polyethylene sheathed with two parallel steel wires as reinforcements.
