Description
GYTY53 double sheathed 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
