GYTA33 Aluminium double jackets direct burial Outdoor Optical Fiber Cable
Performance
GYTA33 is an outdoor communication optical cable of metallic strength member of the loose tube jelly-filled structure, with Al-polyethylene laminated sheath and single-layer thin round steel wire armored polyethylene outer sheath.
The loose tubes are made of high modulus plastics (PBT) and filled withwater resistant filling gel. Loose tubes are stranded around the metallic central strength member, cable core is filled with cable filling compound. The corrugated aluminum tape is longitudinally applied over the cable core, and combined with polyethylene (PE) inner sheath. Galvanized steel wires are stranded around inner sheath, and then extruded with PE outer 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 ensure the cable core reliable performance of moisture-proof and water block
Corrosion resistance phosphated steel wire with high Young's modulus as central strength member givesdesirable tensile strength
Longitudinally Armor with both side coated aluminum tape and stranded steel wires armoring meet therequirements of high crush resistance, tensile strength, bulletproof property, heavy duty direct buryunderwater installation
Strict craft and raw material control enable lifespan over 30 years
