Prysmian increases Sirocco HD cables for FTTx and 5G networks to 864 fibres: new record!


Prysmian increases Sirocco HD cables for FTTx and 5G networks to 864 fibres: new record!

The Sirocco HD microduct cable range, with BendBright-A2 200µm single-mode bend insensitive fibre, has been expanded to include an 864f cable.

The new cable boasts 864 fibres in a diameter of 11.0mm, providing a fibre density of 9.1 fibres per mm2, and is installable into a 13mm duct – with this innovation, Prysman Group has broken its own record. Sirocco HD cables continue to provide the smallest diameters and the highest fibre densities for microduct cables, making it possible to introduce much-needed increased fibre counts into standard microducts.

The cables, utilizing Prysmian’s BendBright-A2 200µ single-mode (ITU-T G.657.A2) bend insensitive fibre, providing a truly future-proof solution that is ideal for supporting FTTx / 5G rollouts. Prysmian PicoTube technology makes cables up to 20% smaller than previous versions. As a result, it becomes possible to install more fibres into congested duct space and enable the use of smaller ducts for new installations, resulting in lower installation costs and the use of less raw materials. In turn, this benefits for both the total cost of network deployment and the environmental footprint. The cables are now available in fibre counts from 96 to 864 and conform to international standards for optical and mechanical performance.

“Bend-insensitive fibre optic cables will be crucial for the building of full fibre networks”

said Ian Griffiths, Global R&D VP, Telecom business at Prysmian Group.

“The extreme fibre count and reduced diameter of the Sirocco HD microduct cables make installation faster and more cost effective. The cables are also sustainable as they are designed for installation into microducts, making them easily deployable in future-fit solutions such as high density access, FTTx and 5G networks."

“One of the biggest challenges was being able to make the cable tubes so small without compromising on usability and mechanical and optical performance. The skills and experience of our R&D teams made this possible and we have developed some interesting new learnings and best practices that we can leverage going forward. Effectively, we are offering a scalable solution that’s high-density, physically compact, and easily deployable for a future-fit solution, thus meeting the evolving needs of the market for years to come.”
