The cable type is longitudinally water-blocked and intended for outdoor use (in ducts). The design can incorporate 12 to 288 fibres in loose tubes with a diameter of 2,25 mm. The individually coloured fibres are tubed in groups of maximum 12, and stranded onto a central dielectric fibre reinforced strength member (FRP). The cable type is longitudinal water-blocked through the use of swellable tape and sheathed with halogen-free black polyethylene.
