Opnext Demos First Real-time, Single Wavelength 100G Field Trial in Europe on TeliaSonera Network

Fremont, Calif.-based provider of high-speed optical communications technology Opnext, Inc. has announced that it has successfully completed the trial of a single wavelength, real-time coherent 127G PM-QPSK (Polarization Multiplexed Quadrature Phase Shift Keying) modem on the TeliaSonera (News - Alert) network running through Sweden.

The first real-time, single wavelength 100G field trial in Europe, the TeliaSonera trial was conducted over a long haul link with 10 Gbps and 40 Gbps mixed traffic and ran from Uppsala, Sweden to Olofström, Sweden and back for a total distance of 1700km and represents the longest un-regenerated real-time test to date.

"TeliaSonera has one of the largest and fastest growing IP backbones in Europe, and this trial demonstrates our focus on maintaining a state of the art network that is ready to use next-generation technologies, such as coherent 100 Gbps, from vendors like Opnext (News - Alert)," said Staffan Göjeryd, Head of Broadband Development, TeliaSonera.

The coherent technology from Opnext ensured that the transmission channel did not require optimization to implement the 100 Gbps technology. Opnext plug and play technology allows carriers to upgrade their existing line systems to 100 Gbps without having to make any change to their existing networks. In addition, there is no need for external dispersion compensation, which results in reduced cost and IP latency.

"100G modem performance is critical to help carriers meet the ever-increasing bandwidth demands from their customers," said Mike Chan, President of the Opnext Subsystems business unit. "This trial represents the longest real-time 100G trial performed to date, moving the industry one step closer to the commercialization of 100G technology."

TeliaSonera has the distinction of being the first operator in the world to commercially launch 4G services to customers in Stockholm, Sweden, and in Oslo, Norway, in 2009. In another article, TMCnet reported that TeliaSonera has launched the world's first 4G Wi-Fi technology service.
