Structure Design

Description

In the GYFTY cable, single-mode/multi-mode fibers are positioned in the loose tubes, which are made of high modulus plastic materials, while the loose tubes strand together around non-metallic central strength member (FRP) into a compact and circular cable core. For certain high fibre count cables, the strength member would be covered with polyethylene (PE). The water-blocking materials are distributed into the interstices of the cable core.Then the cable is completed with a PE sheath.

Application

Adopted to Outdoor distribution. Adopted to trunk,Power system, heavy lightning and places with severe electromagnetic interference.

Features

1.Precise control of the excess length of the optical fiber ensures that the optical cable has good tensile performance and temperature characteristics

2.PBT loose tube material has good hydrolysis resistance, and the tube is filled with special grease to protect the optical fiber

3.Optical cable has excellent flexibility and bending resistance

4.Optical cables are all non-metallic structures, light in weight, easy to lay, and excellent in electromagnetic resistance

5.Smooth outer sheath enables the optical cable to have a smaller coefficient of friction during installation

6.PE sheath has good resistance to solar radiation

7.The following measures are adopted to ensure the waterproof performance of the optical cable: the loose tube is filled with special waterproof compound; the cable core is completely filled
