Optical Goes Alien in German Trial

May 11, 2017

Coriant and Telefónica Germany have successfully completed an alien wavelength trial. The purpose of the trial was to demonstrate how existing optical infrastructure can be optimized with disaggregated and optical transmission and open networking capabilities.

The trial, which took place earlier this year, ran on Telefónica Germany’s existing 10G DWDM dispersion compensated network. It involved disaggregated 100G, 150G, and 200G transmission over live fiber optic links on the network. And it employed the Coriant GrooveT G30 Network Disaggregation Platform.

“The challenge of managing ever-increasing demand for network capacity without incurring escalating operating expenses requires innovative approaches to high-speed optical transmission,” said Michael Haeberle, director of transport and fixed access at Telefónica Germany. “We were very pleased with the performance of the Groove muxponder solution throughout the multiple test cases performed as part of this trial. Groove's compact 1RU form factor, power efficiency, and ease of use were particularly valuable in helping us successfully achieve our trial objectives.”

center interconnect cloud, high-speed metro, and long-haul applications. And it can be used as a muxponder terminal solution and as an Open Line System optical layer solution.

The demonstration with Telefónica Germany is an example of how Coriant is helping operators enable simpler, more flexible, and cost-efficient networks optimized for next-generation services and applications.

In an example of how Coriant is helping operators cope with the challenges of bandwidth growth and faster video streaming, the company’s coherent optical transport technology was recently showcased in the first phase of AT&T's successful 400GbE service trial. This was a long-haul trial across the AT&T global backbone from New York to Washington.

Coriant is also involved in a field trial with Telia Carrier related to the Facebook Voyager white box effort. This illustrates the companies’ efforts to make networks more open.

Day 4, Cisco Live! - The Wrap

Day 4 was the final day of our first ever Cisco Live! We had a great show, with many great conversations and new connections with existing and potential end users, resellers, partners and job hunters.

Day 3, Cisco Live!

Day 3 of Cisco Live is history! For Fiber Mountain, we continued to enjoy visits from decision makers and influencers who were eager to share their data center and structured cabling challenges.

Day 2, Cisco Live!

Tuesday was Day 2 of Cisco Live for Fiber Mountain and we continued to experience high levels of traffic, with many high value decision makers and influencers visiting our booth. One very interesting difference from most conferences I attend is that there are no titles on anyone's show badges. This allows open conversations without people being pretentious. I think this is a very good idea.

Day 1, Cisco Live!

Fiber Mountain is exhibiting at Cisco Live! In Las Vegas for the first time ever! Our first day was hugely successful from just about any perspective - from quantity and quality of booth visitors to successful meetings with customers.
