REFERENCE STANDARDS

The offered fiber optic cable complies to the ITU-T G.652.D, ITU-T G.655.D, ITU-T G.657.A1, IEC 60794-3, IEC 60332-3A,

TIA/ EIA standards.

CONSTRUCTIONS

CABLE STRUCTURE

Fully waterblocked cable

– Each fibers are inserted into thixotropic gel-filled coloured dual-layer thermoplastic (PC-PBT) loose buffer tubes

– Water ingression protection is applied using swellable compound and tape

Dielectric central strength member

– Glass reinforced plastic (GRP/FRP) non-metallic, anti buckling central strength element

SZ-stranded

– Isolates fibers from installation and environmental rigors

– The loose buffer tube and fillers are SZ-stranded around FRP and bound with polyester yarns

Corrugated Steel Tape Armor

– Provides rodent bite protection for direct buried applications

Fire Resistant

– Fire resistant tape applied around the middle jacket

– Used in vital communication and emergency systems that remains operated even during a fire

Low Smoke Zero Halogen Flame Retardant (LSZH FR) jacket

– Black UV resistant Low Smoke Zero Halogen Flame Retardant (LSZH FR) sheath

– Reduces the amount of toxic and corrosive fume emission

– Other sheathing are available upon request.
