Faced with the challenge of ever-expanding demands placed upon connectivity infrastructure, the world’s leading tech players are collaborating to achieve more capacity, affordably.In one recent development, OTE Group and Nokia have announced two new optical transmission rate world records using Nokia’s sixth generation of super-coherent Photonic Service Engine (PSE-6s) technology.
The field trial, which used Nokia’s 1830 PSI-M optical transport solution, ran over OTE Group’s national dense wavelength division multiplexing (DWDM) network, connecting IP Core data centres and routers in Greece. Two optical nodes were installed in Patra and Athens to boost performance over the specific fibre optic routes.
Nokia and OTE achieved record-breaking speeds in a live network in real conditions, transmitting 800Gbps on a single channel over 2,580km, and 900Gbps over 1,290km. This was achieved over a DWDM link transmitting a full load of DWDM channels over 4.8THz of spectrum and supported a total network capacity of 25.6Tbps per fibre. The companies also demonstrated 1.2Tbps transmission on a single channel over 255km.
Running an optical solution with Nokia’s PSE-6s allows the increase of network capacity and spectrum utilization, reduces energy consumption per bit by 40%, and minimizes the network’s carbon footprint.
The trial demonstrates the successful application of delivering high-capacity, long-haul DWDM transmission, paving the way to elevate data transmission capabilities to meet the growing demands of social media, cloud computing, and video streaming.
“We are proud to have developed, constructed and operate one of the most advanced long-haul backbone DWDM networks globally. This network has demonstrated world-record performances, as evidenced by our recent field trial. Our aim is to deliver top tier performance in the most cost-effective manner. In collaboration with our partner, Nokia, we look forward to further advancements in our DWDM technology,” said Michalis Papamichail, OTE Group Core Network Devops and Technology Strategy Director.
