24 and 48 Core SM G652D Dielectric Loose Tube Fiber Optic Cable GYFTY

Description GYFTY (non-metallic strengthening member, loose tube stranded and filled, polyethylene sheathed outdoor optical fiber cable for communication) The structure of the optical cable is to sheath a single-mode or multi-mode optical fiber into a high-modulus plastic filled with waterproof compound loose In the casing. The center of the cable core is a non-metallic reinforced core (FRP). For certain fiber optic cables, a layer of polyethylene (PE) is extruded outside the non-metallic reinforced core or a non-metallic reinforced yarn is added to the cable core. line. The loose tube (and filling rope) is twisted around the central reinforcing core to form a compact and circular cable core. The gaps in the cable core are filled with water blocking compounds and polyethylene sheaths.
