Cable description
GYFTA53
GYFTA53 (non-metallic reinforced member, loose sheath, aluminum polyethylene bonded sheath, longitudinally wrapped corrugated steel strip armor, polyethylene sheath, credit outdoor optical cable) is a waterproof composite loose tube made of single-mode or multi-mode optical fiber sheathed in high-mode plastic. The center of the cable is a non-metallic core. For some cable cores, a layer of polyethylene (PE) is extruded from the non-metallic reinforced core. The loose tube (and filling rope) is wound around the central reinforcing core to form a compact circular cable core, and the water blocking compound is filled in the gap of the cable core. A layer of polyethylene inner sheath was extruded after longitudinal binding of plastic coated aluminum strip, and polyethylene sheath was extruded after longitudinal binding of double-sided plastic coated steel strip.
