The cable type is intended for combined indoor as well as outdoor use (in ducts). The design can incorporate up to 640 fibres. The fibres are grouped into ribbons consisting each of four fibres (maximum 96 fibres) or 8 fibres (maximum 480 fibres). The 4- or 8-fibre ribbons are stacked in a slotted core profile of polyethylene, which is extruded onto a dielectric fibre reinforced strength member (FRP). The cable type is longitudinal water-blocked through the use of water-swellable materials and sheathed with halogen-free flame-retardant polymeric compound. The cable type fulfils the fire propagation requirements stated in IEC 60332-3 cat.C.
