Product overview
 The structure of GYTA53 optical cable is 250 μ M optical fiber is sheathed in a loose tube made of high modulus material, which is
 filled with waterproof compound. The center of the cable core is a metal reinforced core. For optical cables with some cores, a
 layer of polyethylene (PE) needs to be extruded outside the metal reinforced core. The loose tube (and filling rope) is twisted
 around the central reinforcing core to form a compact and circular cable core, and the gap in the cable core is filled with water
 blocking filler. Plastic coated aluminum strip (APL) is longitudinally wrapped and extruded with a layer of polyethylene inner
 sheath, and double-sided plastic coated steel strip (PSP) is longitudinally wrapped and extruded with polyethylene sheath to form
 a cable.
