Coriant reports the successful completion of a trial to show disaggregated 100G, 150G, and 200G optical transmission over live fibre-optic links in Telefónica Germany’s existing 10G DWDM network.
Conducted earlier this year, the trial showed how an open transmission systems and disaggregated networking technology – in this case using Coriant’s Groove G30 platform – can be used to increase network capacity more than 10-fold, avoiding the need to invest in new fibre.
Alien wavelengths were injected across three different live links in Telefónica’s existing 10G DWDM dispersion compensated network, spanning distances of 1,070km, 630km, and 290km between major network sites, including Düsseldorf and Frankfurt.
While interoperating with Telefónica’s existing 10G optical line system, the Coriant Groove platform successfully transmitted disaggregated 100G transport across all three links, 150G across the 630km and 290km links, and 200G across the 290km link.
“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, 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.”
Later this year, Telefónica Germany and Coriant plan to conduct additional alien wavelength testing with the Coriant Groove G30 muxponder across Telefónica’s 100G national backbone network.
“We look forward to further collaborating with Telefónica Germany as they enhance the capabilities of their optical transport infrastructure to deliver a best-in-class broadband experience,” said Joerg Jannsen, Telefónica Germany executive account manager, Coriant.
