GYTS-48B1.3 Single Mode Armoured GYTS 48 Core Fiber Optical Cable
For Underground
Product Description
The GYTS aerial fiber optic cable features single-mode or multimode
fibers housed within high-modulus plastic loose tubes, with each
250μm fiber individually protected. These tubes contain a
waterproof gel filler for enhanced moisture resistance. The cable
adopts a stranded loose tube design with a dense construction,
utilizing a polyethylene outer sheath. Its hydrolysis-resistant
loose tubes and specialized filling materials guarantee exceptional
durability.
The cable core is formed by helically wrapping the tubes and
fillers around a central strength member, creating a circular
configuration. A protective PSP layer is then applied over the
core, which is further sealed with filling compound. The final
assembly includes a PE outer coating combined with steel tape
reinforcement, providing outstanding crush resistance and moisture
barrier properties. This design gives GYTS cables superior
waterproof characteristics.
Features

fiber
4. Specially designed compact structure is good at preventing loose
tubes from shrinking
5. Crush resistance and flexibility
6: PE sheath protects cable from ultraviolet radiation
7. The following measures are taken to ensure the cable watertight:
8. Steel wire used as the central strength member
9. Loose tube filling compound
10. 100% cable core filling
11. PSP enhancing moisture-proof
