Nokia’ s ICE7 coherent optics upgrade provides a

increase in network capacity

EXA has a huge network in Europe, North America and Africa with more than 3,000 possible route combinations, and has invested heavily to upgrade that network to allow for more capacity to be built and sold. This involved building more than / in excess of 200,000km of new flex network, Ciarán says, which dynamically allocates bandwidth on a fibre cable rather than being restricted to rigid, fixed frequency channels.

The firm also upgraded its optical backbone with advanced photonics – including Nokia’ s ICE7 coherent optics – to increase network capacity by up to 15 % while cutting energy use
