72 Core G.657A1 Blown Fiber Optic Air Blown Optic Cable A-D (ZN)4Y 9/125 Mikrokabel
Description
The structure of gcyfty optical cable is that single-mode or multi-mode optical fiber is sheathed in a loose sleeve made of high modulus polyester material, and the sleeve is filled with waterproof compound. The center of the cable is a non-metallic reinforced core. The loose tube is twisted around the central reinforced core to form a compact round cable core. The gap in the cable core is filled with water blocking filler, and the cable is longitudinally wrapped with polyethylene sheath.
