Kabel Desain Standar Telkom
Spesifikasi Teknis
GENERAL

The cable is applicable for outdoor, direct burial, inside HDPE ducts, or on cable trays or on cable ladders.

REFERENCE STANDARDS

The offered fiber optic cable complies to the ITU-T G.652.D, ITU-T G.655.C, ITU-T G.655.D, IEC 60794-3, STEL K-016-2009 versi 2.1, 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

Double Polymer Coated Aluminium Tape

– Aluminium tape as a mositure barrier

Corrugated Steel Tape Armor

– Provides rodent bite protection for direct buried applications

Pelindung High Density Polyethylene (HDPE)

– Black UV resistant High Density Polyethylene (HDPE) jacket as outer protection

– Good abrasion & scratch resistance

 – Excellent weathering and UV resistance
