Submarine Fiber Optic Cable Double Armored

GYTY33 submarine fiber optic cable suits the underwater laying environment. It is armored with corrugated steel tape, steel wire, double sheath and water-blocking filling compound, therefore protecting itself from subsea and suitable for undersea communication.


  • Double armored fiber optic cable with corrugated steel tape and steel wire
  • Water-blocking tape and materials
  • Steel wire armoring (SWA) improves tensile and impact resistance
  • Crush resistance and flexibility
  • Good mechanical properties and temperature characteristics
  • Loose tube filled with special tube filling compound ensure critical protection for fiber


Underwater, Climbing, Direct burial
