Gyfts 24 Single Mode 24 Core Direct Buried Fiber Optic Cable

Product Description

Basic Information
 

The GYFTS fibers, single mode or muti mode , are positioned in a loose tube made of a high modulus plastic. The tubes inside are gel free. A FRP, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The PSP is longitudinally applied over the cable core,water-blocking tape been layed outside of the cable core to protect it from water ingress. The cable is completed with a PE sheath.
 

Features
 

Good mechanical and temperature performance

Gel free loose tube.

Crush resistance and flexibility

PE sheath protects cable from ultraviolet radiation
FRP used as the central strength member

PSP and water-blokcing tape enhancing moisture-proof
