Fire Resistance Corrugated Steep Tape Armor (CSTA)
Spesifikasi Teknis
GENERAL

The cable is applicable for indoor, outdoor, direct burial for underground networks. The cable can also be installed on cable trays and on cable ladders

REFERENCE STANDARDS

The offered fiber optic cable complies to the the ITU-T G.652.D, ITU-T G.654.B, ITU-T G.654.C, ITU-T G.655.C, ITU-T G.655.D, ITU-T G.657.A1, IEC 60794-3, TIA/ EIA standards. Fiber type is optional, following to the customer request.

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 as outer protection

– The thermoplastic sheath does not promote the growth of fungus and be free of pits, splits and blisters

– Reduces the amount of toxic and corrosive fume emission

– Other sheathing are available upon request
