Fiber optic cable for outdoor use in ducts. The design can incorporate 2 to 288 primary coated fibres in loose tubes. The individually coloured fibres are placed in individually colored tubed, and stranded onto a central dielectric fibre reinforced strength member (FRP). GRHL Ultimate™ is longitudinal water-blocked through the use of swellable yarn and sheathed with halogen-free black polyethylene. The cable is optimzed for long installation lengths with blowing techniques in micro ducts from 5,5 mm depending on the fiber count and cable outer diameter.

 

Quality and environmental management system

Certified according to ISO 9001, IRIS, ISO/TS 16949 and ISO 14001.
