Japanese researchers from Tohoku University have improved a number of existing network protocols, allowing advanced fiber- optic communication lines were able to transmit terabits of data in seconds.
According to the developers, through their design, for a second, you can download polnoforatny movie in HD-quality.
The university explained that in their development is osnonve Technology QAM (Quadrature Amplitude Modulation), which is widely used by some digital TV tuners and wireless network devices. From a technical point of view of technology is quite complex quadrature modulation.
The simplest explanation of this technology can be reduced to the fact that this development represents a type of signal modulation. In the quadrature there is not one of manipulation, as is usually the case, the carrier, and two, but each of them different from each other in phase, amplitude, and modulation.
In practice, this means that when using a single carrier can transmit multiple bits of data.
So far, this technique is used primarily in wireless communications. In the optical signal, which is present in the cable, to realize the quadrature modulation system was difficult due to the nature of the light signal, and the instability of the radiation.
However, the Japanese experts managed to stabilize the system by using a special laser that supports modulation.
In Tohoku University explained that while up to the commercialization of their development is far, but over the commercialization of the development work there.
