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.
The recent Covid-19 pandemic has changed many areas of our daily life, from going to a place of work, how we spend our holidays, to eating out and socialising with friends and family. For fibre engineers, it has arguably had a much greater impact.
In 2020, video calls have become ubiquitous thanks to Covid-19, revealing many people’s ‘lousy home broadband’, according to Geoff Bennett, director, solutions and technology, at Infinera.
It’s reasonable to say that the biggest disruptive influence this year has been the global pandemic that still currently has a grip on our lives.
