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 thermoplastic (PC-PBT) loose buffer tubes

– Water ingression protection is applied using swellable compound and tape

Dielectric central strength member

– Requires no grounding on cable core part

– 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

Supporting Strength Element Figure-8

– Galvanized steel messenger wire 7 x Ø1.2 mm

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
