Telenor Group is replacing its legacy optical backbone network across Norway and Sweden and has selected Nokia as sole supplier for the work. The upgrade will involve replacing its current optical core network, which connects major centres across Norway and Sweden. It is designed to provide a much-needed increase in bandwidth capacity throughout the countries.
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
