Stranded loose tube cable with non-metallic

central strength member (GYFTY)

D191/D192

Optic Series
Introduction
PE Sheath
The fibres are placed in a loose tube made of high modulus Compound
plastic. The tubes are filled with a water-resistant filling Tube (PBT)
compound. A piece of Fibre Reinforced Plastic(FRP) locates Jelly
in the center of core as a non-metallic strength member. The Fiber
tubes and fillers are stranded around the strength member FRP
into a compact and circular cable core. The cable is completed
with a polyethylene (PE) sheath.
