FUNET, ADVA claim 800G long-haul record

Nov. 4, 2021
ADVA says it has collaborated with CSC – IT Center for Science, which operates the Finnish University and Research Network (FUNET), to transmit single-channel 800G signals more than 2000 km over a live network.

ADVA (FSE: ADV) says it has collaborated with CSC – IT Center for Science, which operates the Finnish University and Research Network (FUNET), to transmit single-channel 800G signals more than 2000 km – a greater distance on a live network than previously achieved. The record was set during a field trial using the ADVA FSP 3000 TeraFlex CoreChannel platform.

The ADVA FSP 3000 TeraFlex CoreChannel used 140-GBaud subcarrier technology and 150-GHz channel spacing in the trial. The live flex-grid fiber network included multi-degree ROADMs and Raman amplifiers.

“ADVA’s FSP 3000 TeraFlex CoreChannel at 800-Gbps 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 800-Gbps 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,” commented Jani Myyry, senior network specialist at 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.”

“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,” added 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 800 Gbps using a 150-GHz window. Not only does this help to reduce complexity and avoid stranded bandwidth, but it also makes the technology future-proof. 150 GHz is the channel spacing that offers the best balance between fiber 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.”
