Prysmian’s Two Major Innovations Transforming the Telecom Market How These Two Innovations Work Together Together, Sirocco® and FlexRibbon® Technology maximize fiber density, simplify installation, and reduce total network deployment costs—positioning Prysmian as the global leader in total fiber optic cable solutions. Talk to a Prysmian sales representative today to find the right high-density solution for you. Sirocco® Microduct Cable Technology Prysmian’s Sirocco® platform represents a breakthrough in microduct cable engineering, mastering a long pedigree of development. Prysmian’s Sirocco buffer tube material enables higher fiber density, smaller diameters, and more efficient installation than traditional loose tube designs. Key Innovation Highlights • Ultra High Fiber Density: Sirocco® microduct cables use 250-160 µm fibers within PicoTube™ structures, allowing extremely high fiber counts (up to 864F) while maintaining compact diameters. • Manufacturing Advancements: Prysmian’s partnership with Dow introduced the AXELERON™ HDPE jacket, improving toughness, reducing shrinkage, and enabling higher density cable designs with lower environmental impact. • Smaller, Lighter, Faster to Install: The reduced cable diameter enables more fibers to be installed in limited duct space, improving deployment speed and lowering installation costs. • Enabling Next Generation Network Builds: Sirocco®’s compact design plays a critical role in middle mile and long haul deployments, aiding major operators in scaling network capacity quickly. • Sustainable in many ways: Microtechnology overall uses less polyethylene which reduces carbon emissions in production. Smaller, lighter reels of both cable and duct enable more cable per shipment with an overall reduction in freight impacts. Smaller vaults may also be placed in the solution to have less environmental disruption and overall impact. Why It Matters Sirocco® sets a new benchmark for fiber density per mm², enabling operators to maximize duct utilization, reduce construction costs, and deploy high capacity networks faster—critical in an era of explosive bandwidth demand, edge computing expansion, and AI driven data growth. FlexRibbon® Technology – Pardon us while we Flex. Prysmian’s FlexRibbon® Technology redefines ribbon based fiber by combining the splice efficiency of traditional flat ribbons with the flexibility of loose tube fibers, enabling ultra high density cable designs. Key Innovation Highlights • Extreme Flexibility + Mass Fusion Splicing: Intermittently bonded ribbons can fold, roll, or bend without losing ribbon geometry—retaining compatibility with mass fusion splicing while dramatically improving handling and routing. • Record Breaking Fiber Counts: FlexRibbon® cables deliver 1728F, 3456F, and up to 6912F in compact OSP designs, fitting into ducts as small as 1.25–2 inches—up to 38% smaller than traditional flat ribbon equivalents. • Designed for Microduct Compatibility: Unlike conventional flat ribbons, MicroFlex with FlexRibbon® Technology cables work seamlessly in microduct designs, improving one of the biggest limitations of ribbon technologies. • Robust Mechanical Performance: Internal competitive analysis shows superior ribbon shear strength and ultra thin overcoats, making Prysmian’s ribbons the most robust among leading suppliers. • Indoor, OSP, and High Count Versatility: FlexRibbon® cables span indoor flame rated constructions, microduct variants, and ultra high count OSP “hero” cables, including solutions used by major hyperscalers and interconnect providers alike. Why It Matters FlexRibbon® delivers the highest fiber counts in a wide variety of cable footprints, supporting hyperscale data centers, wireless densification, cloud interconnects, and high capacity metro fiber builds. It enables operators to scale capacity without needing larger ducts or additional civil work—significantly reducing rollout time and cost.
