GYTA / GYTS Fiber Optic Cable

GYTA / GYTS Fiber Optic Cable


The structure of GYTA optical cable is that single-mode or multi-mode optical fiber is sheathed in a loose tube made of high modulus polyester material, and the tube is filled with waterproof compound. The center of the cable core is a metal reinforced core. For certain GYTA fiber cable or gyts fiber optic cable, a layer of polyethylene (PE) needs to be squeezed outside the metal reinforced core. The loose tube (and filling rope) is twisted around the central reinforcing core to form a compact circular cable core, and the gaps in the cable core are filled with water blocking fillers. Plastic-coated aluminum tape (APL) is longitudinally wrapped and then extruded into a cable with a polyethylene sheath. 


As one of the professional fiber optic accessories suppliers, TUOLIMA can customize the optical cable according to your requirements. If you need any technical support, we will also recommend the most suitable and cost-effective customized ADSS fiber optical cable for you according to the use environment, laying method and terminal customer requirements of the optical cable.
