Cable Introduction
GYTA
Cable Description
The structure of GYTA (metal reinforced component, loose layer twisted filled, aluminum polyethylene sheath communication outdoor optical cable) is that single-mode or multi-mode optical fiber is sheathed into an inner filled waterproof composite loose tube made of high-mode plastic. The center of the cable core is a metal reinforced core. For some cable cores, metal reinforced cores are also extruded with polyethylene (PE) layers. The loose tube (and filling rope) is wound around the central reinforcing core to form a tight round cable core, and the gap between the cable cores is filled with water blocking compound. Extruded polyethylene sheath after longitudinal winding of plastic coated aluminum tape.
