Optical fibers are housed in loose tubes that are made of high-modulus plastic and filled with waterproof compounds.
FRP is applied as central strength member.
Loose tubes are SZ-stranded around the strength member.
Water blocking yarns are used in and over the cable core to prevent it from water ingress.
Polyethylene sheath is applied over the cable core as the outer sheath.
Features and Benefits:
1. Optimum cable structure, high fibre density.
2. Accurate fibre length balance, ensure stable performance.
3. No gel in cable core for water blocking, low carbon and environmental.
4. Structure Innovation in sheath, enhancing the blowing performance.
