London scientists have reported a new record in the fiber optic network. Here they are said to have achieved a data rate of an impressive 178.08 terabits per second.
Cooperation between Japan and England
With the immensely high data rate, the University College of London (UCL) has doubled the speed of the world’s fastest Internet connection to date. In addition, they were able to beat the previous world record. This was one fifth slower. The test object was a 40 km long fiber optic network. The experiment was a collaboration between a Japanese telecommunications operator and the UCL.
Various amplifier technologies
But how did the scientists achieve these high data transmission rates? The key to success was probably a combination of several different amplifier technologies. These technologies combined to boost the signal. The researchers used what are known as self-developed geometric shaping constellations. This involves adapting and optimizing the light signals accordingly. This...
