Optical fibers are housed in loose tubes that are made of high-modulus plastic and filled with waterproof compounds.
Steel Wire is applied as central strength member.
Loose tubes are SZ stranded around the central strength member.
Water blocking jelly is used in and over the cable core to prevent it from water ingress. Polyethylene sheath are applied as inner and outer sheath.
Share:
vide the fibers with enough space and bending endurance, which ensure good optical property of the fibers in the cable.
Accurate process control ensures good mechanical and temperature performance.
High quality raw material guarantees the long service life of cable.
