Prysmian has released a range of nano loose tube cables with smaller diameter and increased fibre density, part of the complete nano LT cable family. The range allow the introduction of 192 fibres into standard 10/12 mm ducts and 96 fibres into standard 8/10 mm ducts.
The cables make it possible to realise download speeds of 30-40 Mbps on legacy portions of the network. Operators can invest in phases and decide to upgrade the final portion of the network at a later date. The loose tube solutions make the most of several existing Prysmian Group strengths. On the basis of the bend insensitive BendBrightXS fibre, the cables make it possible to offer highest densities in confined spaces, without sacrificing quality and durability. The jetting/blowing know-how ensures the cable is properly distributed along distances up to 1.5 km.
This new approach is suitable for operators and incumbents looking for new ways of deploying FTTH effectively and cost-efficiently, vastly increasing fibre density to accommodate VDSL2 and realising vast economies of scale. It allows them to re-use existing infrastructure, regardless of local requirements regarding cable type and quality. Excessive splicing can be avoided, for example, due to the high standards of the last-mile solutions.
