Aerial ADSS Non Metallic Cables, Capacity up to 312 fibers

Technical Specification

Aerial All Dielectric Self Supporting (ADSS) Optical Fiber Cables

GENERAL

The cable is for outdoor application installed as aerial cable on up to 100-m pole distance (span) or as duct cable installed inside HDPE sub duct

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, ITU-T G.657.A1, IEC 60794-3, 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

All-dielectric cable construction

– Requires no grounding

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

– Aramid yarns as a tensile strength element

High Density Polyethylene (HDPE) jacket

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

– Good abrasion & scratch resistance

Excellent weathering and UV resistance
