Product Description

Products Description

Mini central tube type air-blown optical cable is to place colored 2-24 core optical fibers in the bundle tube, and extrude a layer of high-density polyethylene outer sheath.

Features

1. Special composite material loose tube, reducing the retraction of low temperature tube;
2. Precisely control the excess length of the optical fiber, and the performance of the optical cable is stable;
3. Unique process control to prevent sheath wrinkling during air blowing;
4. Outer sheath of high-density polyethylene to increase the air blowing distance.

Standard

IEC 60794-5IEC 60794-1-2 or YD/T 1460-2006

Specification

The GCYFXY series is designed for air-blowing installation in micro-ducts, featuring high fiber density and low friction HDPE sheaths.
