Opnext, TeliaSonera demo longest live 100 Gigabit link on largest EU IP network

FREMONT, USA: Opnext Inc., a leader in high speed optical communications technology, has demonstrated a single wavelength, real-time coherent 127G PM-QPSK (Polarization Multiplexed Quadrature Phase Shift Keying) modem on the TeliaSonera network running through Sweden. The TeliaSonera trial represents the first real-time, single wavelength 100G field trial in Europe.

The trial conducted over a long haul link with 10 Gbps and 40 Gbps mixed traffic 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," said Staffan Göjeryd, Head of Broadband Development, TeliaSonera.

The transmission channel did not require optimization to implement the 100 Gbps technology, which further demonstrates the ease-of-use of coherent technology from Opnext.

Today, many 10 Gbps and most 40 Gbps optical systems using direct detection require optimization and intervention by an optical network engineer to balance all of the optical impairments on an installed optical fiber.

Opnext plug and play technology allows carriers to upgrade their existing line systems to 100 Gbps without requiring any change to their existing networks. In addition, new systems using Opnext technology can eliminate the need for external dispersion compensation, which reduces cost, minimizes IP latency and allows for deployment over older installed fiber.

"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."
