Adva, Funet demo long-haul 800G over live network

Researchers at the CSC – IT Center for Science, which operates the Finnish University and Research Network (Funet) have transported 800Gb/s farther than ever before over a live network. 

Data was transmitted at 800Gb/s on links exceeding 2,000km and the team says that the trial shows how network operators can leverage new value in existing large-scale infrastructure and how Funet can empower the Nordics’ academics and scientists to achieve even more. ADVA’s 140GBd sub-carrier technology was selected for the demonstration, including the new CoreChannel sled, which leverages 150GHz channel spacing, enabling TeraFlex to deliver long reach for a single-channel 800Gb/s solution.

Jani Myyry, senior network specialist at CSC/Funet said: ‘The new 800Gb/s channel technology will give us more flexibility to choose optimum modulation per use case to improve spectral efficiency. And, more importantly, it maps efficiently to 400GbE client services. This field trial demonstrates that our network can smoothly support future requirements and deliver even more to our users in the Finnish research and education community. It also will strengthen our confidence that the first multi-Terabit services we aim to deliver early next year together with other Nordic research and education networks can be implemented successfully.’

Cornelius Fürst, director, product line management at Adva added: ‘One of the reasons our FSP 3000 TeraFlex CoreChannel is able to provide such great long-haul performance is that it carries data at 800Gb/s using a 150GHz window. Not only does this help to reduce complexity and avoid stranded bandwidth, but it also makes the technology future-proof. 150GHz is the channel spacing that offers the best balance between fibre capacity and optical reach. That’s why it’s gaining traction across the industry.’
