Duct Fiber Optical Cable

Description of Duct Fiber Cable
Duct fiber optic cable includes metallic and dielectric cables, and the number of fibers is 2 up to 288 fibers. The duct fiber optic cable is with aluminum foil as the moisture barrier layer, and aramid Kevlar is for tensile strength support. Glass yarn or polyamide is used to prevent rodents.
According to the number of fiber cores, the structure of different types of duct fiber cables can be divided into a central tube type, a layer stranded type, Users can make corresponding requirements according to conditions of projects.

Duct Tube Fiber cable --GYTA
GYTA cable is a layer stranded structure. The optical fiber is placed in a loose tube, and the sleeve is filled with a waterproof compound. The center part is a metal reinforced member. For some fiber cable structure, a layer of polyethylene (PE) is required to be coasted outside the metal reinforced member. The loose tube (and the filling rope) is twisted around the central reinforcing member into a compact circular cable and filled with a water blocking system. The plastic coated aluminum strip (APL) is longitudinally wrapped and extruded into a polyethylene sheath to form a cable.

The structure of the GYTA cable is shown in Figure 1.1.
