Prysmian Group: BU Multimedia Solutions now offers fibre optic portfolio with improved bending performance according to standard G.657.A1

Higher Bend Insensitivity of Draka single mode fibre optic cables

Cologne/Germany, 4th September, 2020. BU Multimedia Solutions (MMS) of Prysmian Group has upgraded its portfolio of Draka single-mode fibre optic cables with lower bend sensitivity. With the upgrade of G.652.D fibre to the performance profile of G.657.A1 fibre, customers will benefit from higher bend insensitivity of their installed fibre optic network cables. Draka G.657.A1 fibres offer the highest reliability and performance, as well as low bending losses - especially in critical situations. They allow tight installation radii and are fully compatible with G.652.D fibres. The cables are offered at the same price.




The ever-increasing data traffic leads to an exploding demand for transmission capacity and network infrastructure. In addition, new technologies such as 5G, Internet of Things (IoT) and artificial intelligence support this trend. Optical networks must adapt to these requirements as quickly as possible by increasing their dynamics, offering higher capacities and lower latency. At the same time, density is increasing and optical networks are reaching their limits in terms of space.




"All of this leads to fibre bends becoming more and more likely to occur. Preventing power leakage due to bending effects therefore plays an increasingly important role in the necessary transition to flexible and reliable fibre optic connectivity," says Gerard Pera, Product Manager Optical Data Cable of MMS, Prysmian Group. MMS is responding to the new requirements by upgrading Draka's single mode fibre optic cables from G.652.D fibre to G.657.A1. Gerard Pera: "Our new fibre optic cables are much less sensitive to bending without causing high losses. This applies to installation in floor, door and window strips as well as in racks where the cables are heavily bent due to lack of space".




Compared to the G.652.D fibres previously used, G.657.A1 fibres have a much lower attenuation loss. "For example, a G.657.A1 fiber that is insensitive to bending will have an attenuation loss of only 0.2 dB when twisted twice around a pencil, whereas a G.652.D fibre loses up to 11 dB," says Gerard Pera. The improved single-mode fibre has a standard step index profile that is not assisted by additional structures in the cladding. This makes it fully compatible with all installed network applications.


The Prysmian Group has over 30 years at the forefront of fibre optic technology and development. The leading cable manufacturer manufactures all cabling products in its European production facilities. BU MMS develops optimized cable systems built on BendBright fibre technology. Customers benefit from scalable, physically compact and investment-safe solutions that ensure that they are well prepared for future requirements.
