Nokia and Rakuten Mobile, Inc. say they have completed a field trial this past January that saw 1-Tbps per channel transmission between a pair of data center in the Kanto region of Japan using Rakuten Mobile’s commercial DWDM network. The open line system field trial ran over 135 km.

Rakuten Mobile’s fiber network normally operates with 200-Gbps transmission capabilities. The field trial demonstrated the ability to deliver 32 Tbps per fiber in the C-Band and 64 Tbps with the addition of L-Band. The Nokia DWDM line system, featuring the Nokia 1830 Photonic Service Interconnect (PSI)-M, leverages the company’s Photonic Service Engine, optimized for data center interconnect (DCI) applications.

“We are delighted with the performance of 1 Tbps per channel on our optical network in collaboration with Nokia,” commented Tareq Amin, representative director and CEO of Rakuten Mobile. “This technical milestone will allow us to maximize bits per fiber and achieve improved power efficiency. The enhanced capacity will also support our traffic growth, deliver higher bandwidth, and enable Rakuten Mobile to provide new service offerings.”
