Bend-Insensitive Fibres

In 2019, more than 550million kilometres of optical fibre cables were installed globally, compared with just 200million kilometres in 2010. This growth is expected to continue with the invention and adoption of new technologies, driving us into a new era of digital demand. To support the exponential growth of data traffic and adoption of new technologies, it is crucial that we increase the capacity of the world’s optical networks. Optical cabling systems need to offer faster, more reliable and cost-effective deployment methods in order to be future-proof, as well as support the complete optical spectrum – from 1260 nm at the beginning of the Original O-band, up to 1625 and 1675 nm at the ends of the Long L-band and Ultralong U-band. Bend-insensitive single mode fibres (ITU-T G.657.A1 and G.657.A2) are a crucial part of the world’s shift towards flexible and reliable connectivity. They are the only fibres capable of securing the whole fibre spectrum, especially at the longer wavelengths (1625 nm and above), by minimising losses linked to macro- and microbends. These fibres enable the development of extreme fibre count and reduced diameter cabling solutions, so we can meet today’s demand for the highest bandwidth capacity in duct installations. Not only will we see benefits through faster and more stable optical networks, installations will becomemore cost effective, more environmentally friendly, all with lower operational costs as network lifespan increases thanks to higher repair resilience. Over the last 30 years, fibre optic cabling has evolved to support our newera of hyper connectivity, linking continents, countries, cities, antennas and homes. And that is not set to change.
