New record of data rate between single transceivers

In a series of attempts, a team of researchers from University College London were able to make the most rapid transfer of information between one transmitter and one receiver. Speed ​​optical transmission was 1.125 terabits per second.

Lead researcher, Dr Robert Maher, UCL Electronic & Electrical Engineering, said: "While current state-of-the-art commercial optical transmission systems are capable of receiving single channel data rates of up to 100 gigabits per second (Gb/s), we are working with sophisticated equipment in our lab to design the next generation core networking and communications systems that can handle data signals at rates in excess of 1 terabit per second (Tb/s).

"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."

The system, developed by scientists from University College London, uses 15 different channels for data transmission, each of which transmits optical signals of different wavelengths. Each channel is independently modulated and then combined into a single signal, forming a kind as scientists call it, “data superhighway.” At the other end there is only one receiving station with extremely high throughput.
It should be noted that in these experiments, a team of scientists is connected directly to the transmitter and receiver. In the following tests researchers try to connect the two stations by optical fiber, which must be lead to some signal degradation.
