Vodafone and Chinese telecoms equipment vendor Huawei have completed the world’s first successful field trials of 2Tbps optical fibre transmission technologies on Vodafone’s live network in Germany.

The field trial achieved 2Tbps transmission capabilities over 1,500km using a super-channel PDM-16QAM-based high spectral efficiency solution, and a second record-breaking transmission distance of 3,325km using a super-channel Nyquist PDM-QPSK-based ultra-long-haul solution.

Both transmissions were on a link with G.652 fibres and erbium-doped fiber amplifiers (EDFAs) without electrical regeneration.

The link used in the trial was on Vodafone’s live backbone network, passing through a few cities across middle and south Germany.

“We are at the forefront of global 100G deployments, and have taken the lead in delivering key breakthroughs in technologies beyond 100G,” said Jack Wang, president of Huawei’s transport network product line.

“Through collaboration with Vodafone and other leading international operators and customer-centric R&D, Huawei is always ready to build advanced optical networks for customers.”
