Fujitsu Develops Distortion-Compensation DSP for 100 Gbps

Researchers at Fujitsu have developed a digital signal processing algorithm that compensates for waveform distortion in 100 Gbps signals sent over hundreds of kilometers. The researchers believe their DSP could lead to 100 Gbps links at lower cost than today's 10 Gbps within five years.

Some of this research was conducted as part of the "Universal Link Project R&D" sponsored by Japan's National Institute of Information and Communications Technology (NICT). Fujitsu said that scaling conventional, non-linear dispersion compensation techniques would require massive circuits with more than 100 million logic gates. Its new signal-processing algorithm however, requires approximately one-quarter of circuit stages previously thought necessary. The technology has already been tested using a 112 Gbps signal over 1,200 km, and the signal quality using the new five-stage circuit was found to be comparable to that resulting from a conventional 20-stage circuit.

Nokia Siemens Networks Conducts 200G Trial

Nokia Siemens Networks succeeded in transmitting data at 200 Gbps over standard optical fiber. The lab trial, which was conducted at the NSN research facility in Munich, used its recently announced 400G-ready DWDM equipment.

Nokia Siemens Networks said the move to 400G is the next step in the optical transport deployments, following the current 10/40/100G networks. This 200G trial is seen as a stepping stone in this migration. The company expects network operators will start deploying 400G-ready optical networks by 2011.

"Nokia Siemens Networks has time and again demonstrated its capacity leadership in optical networks. Our latest trial shows that it's possible today to re-use existing fiber and double the speed per wavelength to 200G," said Oliver Jahreis, head of product management for WDM networks at Nokia Siemens Networks. "This development is an important milestone and shows that we are on the right track toward a cost-efficient approach to 400G networks and beyond."

As the demand for higher-capacity transport networks continues to rise, network operators need to increase the speed per wavelength in their existing networks. It will help operators get the most out of their investments, as laying additional fiber lines to meet the capacity demand is a costly option.

Re-use of existing fiber for the evolution to higher-capacity networks will protect operators' investments, while providing higher data speeds for end users.

Nokia Siemens Networks conducted the trial at its research and development center in Munich using its prototype equipment.
  • In July 2010, Nokia Siemens Networks announced that its hiT 7300 DWDM platform will be ready for native 400 Gbps single carrier optical transmission by Q1 2011. NSN will offer different muxponder cards to take advantage of this capacity, i.e. 10x40G and 4x100G muxed into a 400G wavelength. The company's optical line system will have 96 channel capacity and when the single-carrier 400 Gbps capacity is introduced, the overall system capacity will be 38.4 Tbps (96 channels of 400G).
