GYFS (Corrugated Steel Tape Armoured, Stranded Loose Tube Cable
Duct Optical Fiber Cable
The loose tubes are made of high modulus plastics (PBT) and filled with water resistant filling gel. Loose tubes are stranded around the non-metallic central strength member (FRP), cable core is filled with water blocking tape. The Corrugated Steel Tape is longitudinally applied over the cable core, and combined with a durable Polyethylene (PE) sheath.
