Fujitsu develops 100 Gbps optical network using old protocols and components
Fujitsu Laboratories Ltd. has recently announced their development of their new optical transmission technology that could reach 100 Gbps data transfer speed rates, by only using components and protocols that are meant for 10 Gbps networks.
Fujitsu Laboratories (Research and Development Center) Ltd. has unveiled last a couple of days ago their newly developed high-speed optical data transfer technology. The new light-based data transfer technology easily passes through the standard 10 Gbps limitation, finally reaching the next anticipated speeds of 100 Gbps, but without requiring the use of new components that are not already used in standard 10 Gbps networks.
Fujitsu's new technology uses a discrete multi-tone (DMT) modulation system, with the aid of digital signal processing. It actually uses a "line", or a set of components and communication protocols that are meant for 10 Gbps, but configures it in a way that it greatly enhances their optical transmission network to achieve the claimed speeds, or at least that is what the report claims. Using a power management algorithm, the modulated data stream can then be efficiently be transmitted at very high speeds even when diffused to multiple subcarriers.
Fujitsu has stated that in addition to the 100 Gbps boost, the technology can be used in tandem with a four-channel optical transceiver, multiplying the speed further to 400 Gbps.
A ten-fold improvement in speeds for data centers using what's supposed to be conventional components would surely be more than just helpful, as it could even probably open up new applications for the internet itself. In fact, Fujitsu expects that their technology would be best applied on the current developing state of various business or enterprise-type web-based/cloud services.
