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.
