FlexRibbon® Technology

Designed to Maximize Fiber Density and Duct Space Utilization

Prysmian's FlexRibbon® Technology offers more than just high fiber density; it’s engineered for ultimate convenience. Installation and handling have never been easier with fiber counts reaching up to 6,912 in an incredibly compact design. Known colloquially as Intermittently Bonded Ribbon (IBR), Prysmian’s patented FlexRibbon Technology was one of the original designs dating back to 2018. That means Prysmian continues to innovate with FlexRibbon, enabling it to be used with different fiber coatings and multiple cable constructions. In fact, Prysmian has more FlexRibbon designs than any other vendor offering IBR cables. Those designs include microduct, flat cables and flame-rated designs, elevating usability to a new level. Our dedication to innovation means we're constantly rolling out fresh designs. Stay connected with us to discover the latest advancements and learn how our user-friendly technology can enhance your projects! 

 

What is FlexRibbon® Technology?  

Conventional flat ribbons consist of 12 optical fibers housed within a rigid structure. While this design allows for mass-fusion splicing, it has certain limitations. In contrast, Prysmian's FlexRibbon® Technology uses intermittent fiber-to-fiber bonds, creating a more flexible unit that enables mass-fusion splicing. This innovation effectively addresses the shortcomings of the earlier technology. The result is a ribbon fiber optic cable that can be rolled, folded, or routed in tight spaces without sacrificing performance, offering superior handling, higher fiber density, and faster network deployment.

Cables with FlexRibbon® Technology

One of the early focuses for FlexRibbon® technology was to increase the fiber count for standard duct sizes. Prysmian now offers fiber counts ranging from 1728 to 6912, optimized for 1-1/4”, 1-1/2”, or 2” ducts. Some options come with 250-micron fiber, while others have smaller 200-micron fiber. For more details, you can refer to our product datasheets.

Microduct cables are an efficient choice for cable deployment, but many customers prefer ribbon cables due to their ease of splicing. While traditional (flat) ribbons are incompatible with microducts, our innovative FlexRibbon technology is. Explore our product datasheets for more details.

Hero cables, such as our 6912, are only made possible with FlexRibbon technology. This technology also offers revolutionary advantages for lower fiber counts. Visit our product datasheets for more information.

Prysmian's new EcoSpan™ is a low fiber-count cabling solution for rural areas. It combines the convenience of an aerial drop with the capability to support spans up to 300 feet and fiber counts of up to 72. This solution is optimized for quick installation on utility poles and is compatible with high-strength wedge clamps and mass-fusion splicing, allowing for seamless integration with your existing infrastructure. Unlike traditional fiber drops, EcoSpan can safely handle spans up to 300 feet under NESC Heavy loading standards.

FlexRibbon® Splicing Demo

Prysmian's FlexRibbon® technology is designed to maximize fiber density and optimize duct utilization, allowing the highest fiber count to be packed into the smallest cable. This technology offers the benefits of mass fusion splicing while differing from traditional cables, which hold fibers in a fixed arrangement. In contrast, FlexRibbon keeps the fibers together more flexibly. This video illustrates the splicing process for 250-micron FlexRibbon fibers.
