As ultrafast fibre optic connectivity, fibre to the home, rolls out faster than ever, gigabit passive optical networks look set to be the technology of choice. UK-based analyst business, Informa, forecasts GPON will account for three out of five subscriptions, worldwide, by end-2018, helped by China-based operators shifting investment from ethernet passive optical networks to this flavour of PON. So what’s the attraction?
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
