Bend-insensitive fibres significantly reduce losses, boost lifetime
Prysmian Group highlights the impact of leveraging bend-insensitive fibres across the entire wavelength spectrum used by current and future PON technology

In the new era of hyper connectivity, it is essential that the industry looks to increase the capacity of the world’s optical networks and operators should choose to leverage a cabling system based on bend-insensitive fibres that can keep up with new technologies, according to Prysmian Group in its latest Industry Insight.

Bend-insensitive fibres, especially the best performing G.657.A2, can enable the development of extreme fibre count and reduced diameter cabling to provide the highest bandwidth capacity in duct installations and minimise losses linked to macrobends and microbends. Therefore, operators will have access to faster and more stable optical networks, cost-effective and environmentally-friendly installations with lower operating costs and increased network lifespan. Bend resistance can extend the expected network lifetime by improving repair resilience and as such, is beneficial for operators looking to make significant OPEX savings.

“The rising wavelength requirements of PONs and wireless networks drives the need for truly bend-insensitive optical fibres, to become an integral part of Fibre-to the-X (FTTx) and 5G mobile networks,” said Prysmian Group Executive Vice President Telecom Business Philippe Vanhille. “In the new era of hyper connectivity, it is essential that we increase the capacity of the world’s optical networks and operators must choose to leverage a bend-intensive fibre cabling system that can keep up with new technologies. Operators that take advantage of these fibres, and in particular the G.657.A2, will achieve the most potential from their deployed networks.”
