Prysmian extends its leadership in optical fibre innovation

Introduces the world’s first 160 micron bend insensitive fibre setting a new benchmark

Prysmian continues to drive digital innovation with the introduction of its BendBright 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 BendBright 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.

Proprietary technology

“Our proprietary BendBright technology has enabled us to achieve an unprecedented level of fibre miniaturization,” stated Ian Griffiths, VP R&D, Digital Solutions segment at Prysmian. “BendBright 160µm empowers cable designers to dramatically reduce cable dimensions and achieve record-setting cable density,” he added.

Fully compliant with G.652 and G.657.A2 global standards, BendBright 160µm is compatible with all legacy single-mode fibres and features the advanced ColorLock 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, a press statement concluded.
