Non-metallic Strength Member fiber optic cable

Non-metallic Strength Member Cable（GYHTY）

·Description

The fibers, 250μm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A Fiber Reinforced Plastic (FRP) locates in the center of core as a non-metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular core. After the cable core is filled with filling compound, it is covered with thin PE (polyethylene) inner sheath. Then, a layer of aramid yarn is applied as additional strength member and the cable is completed with a polyethylene (PE) outer sheath.

·Characteristics

· Good mechanical and temperature performance

· Aramid yarn strength member ensures good performance of tensile strength

· High strength loose tube that is hydrolysis resistant

· Special tube filling compound ensure a critical protection of fiber

· Crush resistance and flexibility

· The following measures are taken to ensure the cable watertight:

- Single Fiber Reinforced Plastic as the central strength member

- Loose tube filling compound

- 100% cable core filling

·Standards

GYHTY cable complies with Standard YD/T 901-2001as well as IEC 60794-1.
