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.
As the pandemic underlines the value of the internet more than ever, its underlying technology is making one of its biggest transitions for years.
The data centre market is a particularly wide-ranging one, with one of the driving forces in recent years the emergence of the hyperscale data centre or cloud service provider.
As the world struggles to settle into the ‘new normal’, today’s optical networks need to be flexible in their architecture blueprint, while adapting to new technologies to provide the kinds of new capacity and service options to meet accelerated demand for higher bandwidth.
To address the undeniable growing demand for higher bandwidth, optical vendors have been playing their role with the development of various coherent optical transceivers for different areas of the market, each with its own set of design considerations.
The demand for bandwidth has unarguably skyrocketed in recent years, thanks largely to the increased appetite for online gaming, content streaming and social-media use.
The importance of reliable connectivity has never been more recognised than it is now. While ambitious targets have been in place across the world for fibre deployment for some time, the ongoing pandemic has served to push it to the forefront.
