Researchers from Chalmers University of Technology, Sweden, and Tallinn University of Technology, Estonia, have demonstrated a 4,000km fibre-optical transmission link using ultra low-noise, phase-sensitive optical amplifiers. The reach improvement shown is 5.6 times that which is possible when using conventional erbium-doped fibre amplifiers.

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
