ADVA has announced that CSC – IT Center for Science, which operates the Finnish University and Research Network (FUNET), has set an industry record by transporting 800Gbps further than ever before over a live network. Using the ADVA FSP 3000 TeraFlex™ CoreChannel™, FUNET’s succeeded in transmitting data at 800Gbps on links exceeding 2,000km. The field 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. Harnessing 140GBd sub-carrier technology, ADVA’s new CoreChannel™ sled leverages 150GHz channel spacing, enabling TeraFlex™ to deliver the market’s longest reach for a single-channel 800Gbps solution.

“ADVA’s FSP 3000 TeraFlex™ CoreChannel™ at 800Gbps speed delivered impressive reach during our tests and was stable throughout the month-long test period when we ran it on our nationwide ADVA open line system. The new 800Gbps 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,” said Jani Myyry, senior network specialist, CSC/FUNET. “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.”

ADVA says that featuring multi-rate client support, the CoreChannel™ sled can also transport any mix of 400GbE, 100GbE and 10GbE services, protecting investment and providing complete flexibility.

“It’s fantastic to see our FSP 3000 TeraFlex™ with CoreChannel™ sled pass this major test with such flying colors. Even over the FUNET network’s longest distances, the solution surpassed expectations and showed how incredible speeds are now possible at the lowest possible cost per bit per kilometer,” commented Cornelius Fürst, director, product line management, ADVA. “One of the reasons our FSP 3000 TeraFlex™ CoreChannel™ is able to provide such great long-haul performance is that it carries data at 800Gbps 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 and why our open FSP 3000 TeraFlex™ CoreChannel™ sled is ready for new innovation further down the line.”
