How long did it take you to load this page? The answer will vary, however, all of you would agree that it didn’t load up as fast as you’d expect it to. That is the problem that many Internet users are facing nowadays. The Internet speed is just not good enough anymore, however, before you give up hope, you should know that researchers are actually working day and night with only one aim in their mind; bring the data transmission to such a speed that virtually largest data can be sent in a second.
‘That’s a fairytale,’ is your response and we understand that because it sounds too good to be true. Well, you’re lucky because the age you’re living in doesn’t settle for slow Internet speed and wants to improve it further. A team from University College London has just set a new record for the quickest ever data transmission rate between a single receiver and transmitter. The team made use of an optical communications system and carried out data transmission at a rate of 1.125 terabits per second.
Geeks, geeks, listen to us, we know that number doesn’t explain much but wait a minute. Lead researcher, Dr. Robert Maher said, “For comparison this is almost 50,000 times greater than the average speed of a UK broadband connection of 24 megabits per second (Mb/s), which is the current speed defining “superfast” broadband. To give an example, the data rate we have achieved would allow the entire HD Games of Thrones series to be downloaded within one second.”
Well, color us impressed and admit it, you all are drooling as well right now. So how do optical communications actually work? The optical communications system carry out work by sending light’s pulses via an optical fiber instead of using electric current for the transfer of data. The system that has been put together by the team was tinkered with and incorporated a light-emitting diode that is capable of working as a transmitter and converts information and then fires away an electronic signal into a light signal that is picked up by the receiver that converts this light back into electricity.
The system employs use of 15 various channels that are aptly named as ‘super-channels’ and feature different wavelengths of light. The system is subsequently fed into a single optical receiver that features super-high bandwidth for processing.
According to scientific reports, the analysis of the transceiver performance reveals that this impressive method is still quite far away from being employed by internet companies – talk about letting us down. According to the reports, work needs to be done for advancing the system so that it can be used for long-distance transmission and this is a challenge since optical signals are prone to distortion when sent via longer distance channels.
