Of the signals with the researchers of the employed fiber-optic has been proven, could double the distance of the circulate the data without errors by cable U-boat transatlantic relations:high technology news daily.
The new method the potential to reduce the costs of the long-distance optical fiber as the communication signals do not need be promoted electronically about their trip, and this is important if the cables lead spilled or on the floor of the Atlantic Ocean.
How can technical correction these data are damaged or distorted to trip, they could the ability useful fibers. It is on the end of the line at the level of the recipient, without a new components in the context itself. Increase the capacity as important as fiber-optic transport 99% of all data, and the demand is increasing with the growing use of the Internet, but not by the current capacity of fibers and the receivers change much cheaper and easier than Re-Verlegung of cables.
To cope with this increased demand a greater number of information is to be provided, using the infrastructure existing fibers with different frequencies of light creates the data signals. The large number of advertising can interact with each other as sent to distort messages caused the error.
The study in scientific reports today and host of the EPSRC has a new way to improve the distance of the transmission, devissant interactions occur between the various channels such as optical travel approach together with a cable.
Authors of the study by Dr Robert mower (genius electrical and electronic employed), said: " to eliminate the interactions between optical channels, doubling of the distance the signals we can sent without error, 3190km 5890km, is the largest signals for this architecture system. It is a question, a technique for obtaining a parallel group of channels optical, known as a Super-Kanal , with a single receiver. We can the cancellation of the distortion by the posting of the channels of data return on a way virtual digital simultaneously".
The scientists " 16QAM Super-Channel ' includes a set of frequencies that may be code with the help of the Amplitude phase and frequency for a high-capacity optical warning signal. The Super-Kanal was then infestation with the help of a super-high speed receiver and new techniques developed for the treatment of the signal input enabled the Group as a whole and all chains without error. The researchers are now testing the new method on closer Super-Kanale widely used in the digital cable (64QAM), cable modems (256 maq) and the connections Ethernet (1024QAM).
Study author Professor Polina bayvel (Electronic & electrical engineering) Professor optical communications and networks and director UNLOC, said: "We are excited to be an important statement allows the improvement of the communication of optical fibers. Our procedure improves the efficiency of the transmission of the data -- almost double the distance of transmission can be achieved, with the possibility, substantial savings on the current state of the art of the operating systems. One of the biggest global challenges that we face is that of maintaining the communication with the application of the Internet in full expansion -- overcoming the capacity constraints for optical fiber cables is a big part of the solution to this problem."
