The benefits of superfast broadband are well established, but the best way of installing the fibre is still being debated. Established models range from fully government-owned fibre, through to fully privatised models that rely on service providers to get services up and running. Choosing the right model, and rolling out fibre deployments effectively using the chosen model, is a task that varies with geography, subscriber density, demand, and the willingness of telecommunications companies and government to invest in the backbone of the optical communications network.
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
