Cloud data centres bring valuable services that many of us are progressively accepting into our daily lives – and in doing so, push optical communication’s limits. ‘The premier league cloud data centres have this tremendous appetite for more bandwidth,’ comments Andy Bechtolsheim, chief development officer at Arista Networks in Santa Clara, US. They expect their bandwidth needs to double every two years or so, he says.
Cost and compatibility can make a compelling case for pushing 100Gb/s bandwidth over a single optical channel, both as individual links and supporting 400Gb/s Ethernet, finds Andy Extance
Robin Mersh takes a look at how the industry is creating next-generation optical access fit for 5G
Technological advances to aid the increasing demand for bandwidth, on the path towards the terabit network, should lead to optical signals that are flexible and adaptive, like water, argues Dr Maxim Kuschnerov and Dr Yin Wang
