Description

The GJYWFH optical cable is a non-metallic reinforced indoor optical cable, featuring a steel wire reinforced sheath and LSZH materials. It is suitable for scenarios with high requirements for lightning protection, flame retardancy and mechanical strength (such as railway communication and power systems, etc.).

Features

Small in size, light in weight, and compact in structure;
Using flexible optical fibers reduces the sensitivity to bending, enhancing the network transmission characteristics;
Using LSZH, and environmental protection;

Applications

This type of optical cable is mainly used for indoor wiring and is suitable for installation in conduits or duct ways.
