GYTS53 Outdoor Communication Large-Core Structure Directly Buried Anti-Ant Double Armoured Fiber Optical Cable
The structure of GYTS53 optical cable features 250μm optical fiber sheathed in a loose tube made of high modulus material, with the loose tube filled with waterproof compound. The cable core center contains a metal reinforced core. For certain optical fiber cables, a layer of polyethylene (PE) is extruded outside the metal reinforced core. The loose tube (and filler rope) is twisted around the central reinforcing core to form a compact, round cable core, with gaps filled with water blocking fillers. Plastic coated steel tape is longitudinally wrapped and then extruded with a polyethylene inner sheath. Double-sided plastic coated steel tape (PSP) is longitudinally wrapped and then extruded with polyethylene sheath to complete the cable assembly.
- Adopting "SZ" bidirectional layer twisting technology
- Filling water-blocking ointment step by step, water-blocking in full section
- The steel (aluminum) belt has reliable bonding with the edge, high strength, and no cracking when twisted
- Stable fiber excess length control
- After the cable is formed, the additional attenuation of the fiber is almost zero, and the dispersion value does not change
- Excellent environmental performance, applicable temperature range is -10℃ to +70℃

- Cable Core: The loose tubes are stranded around the central strength member utilizing SZ. SZ stranding wraps the tubes in one direction for several turns, then in the other direction.
- Central Strength Member: The central strength member is made of steel. It provides both tensile and anti-buckling strength to the cable.
- Loose Tube: Optical fibers are housed in jelly filled tube. The tube is manufactured with industry standard PBT. It is colored for easy identification according to the scheme shown above.
- Water Blocking Material: Filling compound, the water blocking material between the loose tube and the inner sheath protect cable from water intrusion.
- Armour: Two layer of corrugated steel tape provide additional cable compression strength, maximum anti-crush property, rodent protection and bullet resistant performance.
- Outer Jacket: A black high density polyethylene jacket is extruded over the cable core and corrugated steel tape armor as the sheath.
- Cable Sheath Marking: Each cable have the following information clearly marked on the outer jacket of cables: manufacturer name, year of manufacture, cable and fiber type, length mark, or as customer's requirements.
