Stranded Loose Tube Non-metallic Strength Member Non-armored Cable (GYFTY)

1) Description

Stranded loose tube cable with non-metallic center strength member.
The fibers, either single or multi-mode type, are placed in a loose tube made of a high modulus plastic. The tubes are filled with a water resistant filling compound. A steel wire sometimes shielded with Polyethylene (PE) for cable with big fiber quantity, locates in the center of the cable as a metallic strength member. Tubes and fillers are stranded around the strength member into a compact and circular cable core. The cable is completed with a PE sheath.

2) Application

Long-distance communication, local trunk line, CATV & computer networks system.

3) Structure:

4) Technical characteristics

Low dispersion and attenuation
Proper design, precise control for fiber excess length and distinct stranding process render the cable excellent mechanical and environmental properties
With good anti-electromagnetism ability
With small cable diameter, light cable weight, easily to lay
