Revolution in Optical data transmission

Revolution in Optical data transmission Year after Year there is increasing demand for bandwidth digital trunks. The emergence of Internet TV in 3d has led to the fact that many European providers just drown in the data stream. Europe is trying to increase the capacity of their networks trying to use satellites and new technical solutions based on older technology. In fact constructed in another parallel line, but that decision will come soon end for the flow of data annually just doubled. If so, build, or develop the network, can I just build and build and not to keep pace with progress. Need something completely different solution which would allow to implement with a large stock of the process of information exchange. It is this innovative solution, I decided to you today in my blog to tell. To date, the fastest and the coolest data transfer optics is considered. Each mobile operator has in every city where it is present as a rule its optical ring. If your ring is not, then leased capacity from other operators. But as I wrote earlier every year the needs and increasingly comes a time when even the optics in a simple, her performance will be small. What then And then there will be the following variant of optics, optics broadband!
What it is. Information on this issue a lot, but to understand the essence is possible only in case, if you read everything from cover to cover. I will try planned to chew the essence of the invention. Clever scientists have created a completely different modified device that will transmit over a single optical cable is much greater flow of data. How and on what basis it works. Currently the cable is one of the modulated light stream, and the new technology will allow the laser beam to pass through a device that ressalat on his frequency component and the one light flux in the optical cable with a single transmitter in the path is sent to the receiver 300 individual laser beams and hence it is equivalent bandwidth 300 optical fibre cables. The speed with which information will be forwarded by the cable so so high, that will allow all the information that is contained in the library of Congress to pass electronically in just 10 seconds. How is the speed Really just super! In fact this technology is used a method of packaging one laser beam 300 different colors, a sort of technology "Fourier transform". On this type of data is described in detail in a magazine Nature Photonics.
IN scientific circles this division or the package is simply called "orthogonal frequency division multiplexed", to divide the beam into streams with different frequency. Everything on this topic has long been known, the problem was that there was no real opportunity to create the equipment of transmission and reception of the information collected on this beam into a beam. The transmitter and receiver of the stream is half done, still need to disconnect, modulated, to take protectivity and issue in line, which was implemented in the laboratory. In the near future we should expect widespread application of this technology in telecommunications.
