Finnish R&E network FUNET ran ADVA's TeraFlex through multiple trials, including the creation of 1.2-Tbps channels.

The CSC – IT Center for Science, operator of the Finnish University and Research Network (FUNET), has used the ADVA FSP 3000 TeraFlex platform to test the ability of FUNET’s long-haul links to accommodate 400-Gbps and greater wavelengths. The trials included demonstration of 1.2-Tbps channels for the transport of three 400 Gigabit Ethernet (400GbE) streams over a live meshed ROADM infrastructure, according to ADVA.

The trial covered multiple transmission rates over various distances. The demonstrations included 600 Gbps over 278 km, 400 Gbps over 2,844 km, and 300 Gbps over 4,681 km.

CSC – IT Center for Science originally had planned to deploy ADVA FSP 3000 platforms to provide 200-Gbps capabilities (see “Finland’s FUNET adds ADVA FSP 3000 open line system for 200-Gbps transport”). But, according to Jani Myyry, FUNET network, CSC – IT Center for Science, it became clear that demands were growing at a rapid pace. “Initially, we were aiming for transport based on 100 Gbps and 200 Gbps but are now seeing an increasing need for speeds above that, up to use cases requiring a bandwidth of multiple terabits per second, Myyry explained. “TeraFlex and our ADVA open line system infrastructure enable us to efficiently scale our network with line speeds of 400 Gbps and above. The trials show how TeraFlex dramatically increases flexibility and efficiency for 100GbE and 400GbE transport over long-haul distances.”

“These tests show how it’s now possible to optimize all optical paths over any reach. They demonstrate to the research and education industry that there’s a new way for long-distance networks to support soaring data demand,” commented Henning Hinderthür, vice president, product line management, ADVA. “Together with the CSC – IT Center for Science, we’ve shown how deployed infrastructure operating with coherent channels can transport traffic at unprecedented speeds.”
