  • Product Video
  • Sun Telecom's SUN-OC-CT-SP loose tube light-armored cable (GYXTW) construction is that 250um fibers are positioned in a loose tube which is made of high modulus plastic, filled with a water-resistant filling compound and wrapped with a layer of PSP (Steel Tape) longitudinally; Between the PSP (Steel Tape) and the loose tube a water-blocking material is applied to keep the cable compact and watertight; Two parallel steel wires are placed at the two sides of the steel tape, and the cable is completed with a polyethylene (PE) sheath.
  • Standards
    Sun Telecom’s SUN-OC-CT-SP loose tube light-armored cable (GYXTW) complies with standard IEC60794-1. Standard YD/T 769 is optional.
