There is now a new record for the fastest rate of transmission of data between a receiver and single transmitter by British researchers. They managed to achieve an impressive rate of 1.125 terabits per second with the help of an optical communications system. Robert Maher at University College London mentioned that it is nearly 50,000 times greater compared to the average pace of a 24 MBPS broadband connection in the U.K. For the purpose of a reference, he mentioned that he was able to download the whole Game of Thrones TV series in merely one second. That is simply too fast.
Optical communication systems let data to be transmitted at super fast speeds using pulses of light that are sent via an optical fibre rather than electric current for the transfer of information. A transmitter transforms the electric signal in a light signal upon which the receiver converts this back to electricity. Maher and the entire team combined a total of fifteen channels to transmit data, each of which would carry optical signals bearing different wavelengths. As soon as the information reached at the last stop, it would be combined before it is fed for processing to a receiver possessing super high bandwidth.
Maher explained this further: “Using high-bandwidth super-receivers enables us to receive an entire super-channel in one go. Super-channels are becoming increasingly important for core optical communications systems, which transfer bulk data flows between large cities, countries or even continents. However, using a single receiver varies the levels of performance of each optical sub-channel, so we had to finely optimize both the modulation format and code rate for each optical channel individually to maximize the net information data rate. This ultimately resulted in us achieving the greatest information rate ever recorded using a single receiver.”
This study has been written in much more detail and made part of Scientific Reports as well. Though, the sad part is that this does not mean that the internet speed you get at home would change in the near future. This is due to the fact that super channel component has not yet been commercially produced. Maher and the team will have to demonstrate the same speed in long distance data transmission scenarios in order to make that possible anytime in the future. Until then, we will just have to be content with downloading our favourite TV series at the rate we usually get.
