BendBright XS Whitepaper

In 2006, Prysmian introduced BendBright XS , the first ever-commercialised bend-insensitive G.657 fibre fully compatible with legacy G.652.D fibres, and with regular 250 µm coating diameter. Then, in 2009, Prysmian introduced BendBright XS 200 μm, especially designed for high density access networks. BendBright XS with 200 μm coating diameter (instead of regular 250 μm) offers the possibility to strongly reduce cable diameters. Reduced-diameter fibres have opened an innovative gateway for many new cable systems applicable to a variety of network configurations. One decade later, Prysmian introduced the world ‘s first 180 μm-coated fibre. BendBright XS 180 μm pushes dimensions to an unprecedented lower level and enables cable systems with extreme fibre density. The dimensional reduction corresponds to half of the cross-section area of legacy 250 μm single-mode fibres while preserving a 125μm glass diameter. BendBright XS 180 μm is fully compliant with ITU -T G.652.D and G.657.A2 international recommendations, and it can be spliced with legacy 250 μm single-mode fibre.
