High quality 2-144 cores GYTS53 singlemode outdoor underground
directly burried
armored fiber optic cable
Description
The single-mode or multi-mode fibers are housed within a loose tube
made of high modulus plastic, filled
with a water-resistant compound. In cables with high fiber counts,
a steel wire, sometimes sheathed with
polyethylene, serves as the central metallic strength member. These
tubes, along with fillers, are wrapped
around this strength member, forming a compact circular cable core.
A PSP (Parallel Steel Tape) is longit-
udinally applied over the cable core, filled with the protective
compound to prevent water ingress. Finally,
the cable is encased in a PE sheath for additional protection.
Application
* Adopted to outdoor distribution.
* Suitable for aerial, pipeline laying method, Direct Buried .
* Long distance and local area network communication.
Characteristic
* Reliable mechanical and temperature performance.
* Hydrolysis-resistant, high-strength loose tubes.
* Special tube filling compound for crucial fiber protection.
* Combination of crush resistance and flexibility.
* PE sheath guarding against ultraviolet radiation.
- Watertight measures:
- Steel wire central strength member.
- Compound filling and complete cable core filling in loose tubes.
- PSP (Parallel Steel Tape) for moisture-proofing.
