Prysmian Further Extends its Leadership in Optical Fiber Innovation with the World’s First 160 Micron Bend-Insensitive Fiber, Setting a New Benchmark in Network Miniaturization

Prysmian continues to drive digital innovation with the introduction of its BendBright^XS  160µm single-mode optical fiber—the world’s first of its kind. This breakthrough enables cables to be much smaller and pack more fibers together, which is essential for modern digital networks. Miniaturized, high-density cables allow network operators to fit more data-carrying fibers into limited spaces—such as underground ducts, buildings, and data centers—making installation faster and more cost-effective. 

Building on a legacy of innovation, Prysmian’s new BendBright^XS 160µm fiber paves the way for future cable systems by delivering exceptional fiber density in a significantly reduced diameter. After pioneering the first commercialized 200µm bend insensitive fiber in 2009 and the 180µm version in 2019, Prysmian now sets a new industry milestone with the 160µm launch in 2025. 

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

The 160µm fiber reduces the cross-sectional area by more than half compared to traditional 250µm single-mode fibers, while maintaining a 125µm glass diameter. Fully compliant with G.652 and G.657.A2 global standards, BendBright^XS 160µm is compatible with all legacy single-mode fibers and features the advanced ColorLock^XS  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, BendBright^XS 160µm opens new opportunities for high fiber count cables that are compact, high-density, and easy to deploy—ensuring networks are ready for the future.
