The structure of GYFXY optical cable is to connect 250μThe m optical fiber is inserted into a loose tube made of high modulus material, inside the loose tube Fill with waterproof compound. Two parallel non-metallic FRP reinforcements are placed on both sides of the loose tube and extruded into polyethylene the sheath forms a cable.
