PolyU breaks the world record of fastest optical communications for data centres
The Hong Kong Polytechnic University (PolyU) has achieved the world’s fastest optical communications speed for data centres by reaching 240 G bit/s over 2km, 24 times of the existing speed available in the market. Compared to existing alternatives in the market, the technology developed by PolyU has reduced the cost of data transmission per unit to just one-fourth, and therefore is practical for commercialisation purposes. Speedy transmission at a significantly low cost for data centres enables end users to widely use new forms of communications such as immersive videos, augmented reality and virtual reality.
On a societal level, the increased transmission speed will open up a new era for Big Data and Internet of Things (IoT) applications, driving innovation and technology advancement.
With this breakthrough, around 10,000 persons can stream 4K video at the same time, compared to only 400 persons under the current available speed.
