Prysmian continues to drive digital innovation with the introduction of its BendBrightXS 160µm single-mode optical fibre—the world’s first of its kind. This breakthrough enables cables to be much smaller and pack more fibres together, which is essential for modern digital networks. Miniaturized, high-density cables allow network operators to fit more data-carrying fibres into limited spaces—such as underground ducts, buildings, and data centres—making installation faster and more cost-effective.
Building on a legacy of innovation, Prysmian’s new BendBrightXS 160µm fibre paves the way for future cable systems by delivering exceptional fibre density in a significantly reduced diameter. After pioneering the first commercialized 200µm bend insensitive fibre in 2009 and the 180µm version in 2019, Prysmian now sets a new industry milestone with the 160µm launch in 2025.
“Our proprietary BendBrightXS technology has enabled us to achieve an unprecedented level of fibre miniaturization,” says
Ian Griffiths, VP R&D, Digital Solutions segment at Prysmian. “BendBrightXS 160µm empowers cable designers to dramatically reduce cable dimensions and achieve record-setting cable density.””
The 160µm fibre reduces the cross-sectional area by more than half compared to traditional 250µm single-mode fibres, while maintaining a 125µm glass diameter. Fully compliant with G.652 and G.657.A2 global standards, BendBrightXS 160µm is compatible with all legacy single-mode fibres and features the advanced ColorLockXS coating system for superior bend performance and mechanical reliability.
Prysmian’s sustained investment in R&D and product innovation has made this achievement possible, enabling the company to deliver world-class, high-quality solutions that meet the evolving demands of global connectivity.
As network operators prepare for tomorrow’s connectivity needs, BendBrightXS 160µm opens new opportunities for high fibre count cables that are compact, high-density, and easy to deploy—ensuring networks are ready for the future.
