Stranded Loose Tube Non-armored Cable (GYTA)
Overview
The fibers are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. An Aluminum Polyethylene Laminate (APL) is applied around the cable core, which is filled with the filling compound to protect it from water ingress. The cable is completed with a PE sheath.
Key Features
- Accurate process control ensuring good mechanical and temperature performances
- The material of loose tubes with good hydrolysis resistance and relatively high strength
- Tube filling compound providing the key protection for fibers
- Using small-sized B6a2 fibers with good micro and macro bending performance
- Water resistance of optical cable is ensured by the following measures:
Special water-blocking compound filled in loose tubes
Laminated aluminum tape armor
Cable filling compound ensuring longitudinal water resistance
Standards
- IEC 60794-1
