GYTY53 Double PE Sheath Direct Burial 72 Core optical fiber cable

Product Description

  GYTY53 underground fiber optic cable is an outdoor communication optical cable of metal strength member of the loose tube jelly-filled structure, with polyethylene laminated sheath longitudinally covered with corrugated steel-tape armored polyethylene outer sheath.

  The loose tubes are made of high modulus plastics (PBT) and filled with water resistant filling gel. Loose tubes are stranded around the metallic central strength member, cable core is filled with cable filling compound. Polyethylene (PE) is extruded as inner sheath, then water swollen yarns and corrugated steel tape are longitudinally applied over the inner sheath, and combined with a durable PE sheath.

Feature

• High quality optical fiber provides good transmission performance
• Accurate fiber excess length control ensures excellent mechanical and temperature performance
• Special filling gel filled loose tubes provide perfect optical fiber protection
• All section water blocking provide reliable performance of moisture-proof and water block
• Corrosion resistance phosphated steel wire with high Young's modulus as central strength member gives high tensile strength
• Longitudinal corrugated steel tape presents desirable crush resistance
• Strict craft and raw material control enable lifespan over 30 years 

Performance:

• Applications: Suitable for long-distance communication and indoor communication
• Way of laying: Direct burial,
• Operating temperature: -40 ~ + 70 °C
• Bend radius: Static 12.5x cable diameter   Dynamic 25x cable diameter
