Fujitsu Develops Digital Signal Processing Algorithm for Long-Haul Fiber-Optic Transmissions

Fujitsu Laboratories, Fujitsu, and Fujitsu Research and Development Center of China have announced the development of a new digital signal processing algorithm.

The algorithm compensates for the waveform distortion in signals transmitted over fiber-optic lines, for long-haul transmission systems. Fujitsu has also reduced the size of the circuitry by about 70%.

The development will introduce over 100 Gbps per wavelength transmission speed in long-haul fiber-optic transmission systems with a reduced cost as compared to traditional 10Gbps systems. The new technology of Fujitsu will deploy this type of systems in five years.

Fujitsu’s advancements will replace the 10 Gbps lines with faster fiber lines in the long-haul and regional optical networks. A part of the research was performed under the Universal Link Project R&D. National Institute of Information and Communications Technology (NICT) in Japan sponsored the Universal Link Project R&D. The technology was demonstrated at the 36th European Conference and Exhibition on Optical Communication ECOC2010.
