Description of Product:

   In the structure of Model GYTA optical cable, the single mode or multimode optical fibers are jacketed by loose tube and the tube is made of high modulus plastics. Inside the tube ,it is filled with waterproof filling compound. One piece of metallic reinforced core is in the center of cable core. For some optical cable with number of cores, a layer of extruded PE functions jacket of the metallic reinforced core. Surrounding the center reinfored core, the loose tube (and filling cord) is twisted into a compact and round cable core.The gaps within the cable core are filled with waterproof compound. After it is longitudinally wrapped by plastic coated aluminum tapes (APL), PE sheath is extruded to form an optical cable.
