Telecom Lead Asia: Huawei and Vodafone announced the trial of 2 Tbit/s optical fiber transmission technologies on Vodafone’s live network.

The field trial achieved 2 Tbit/s transmission capabilities of over 3,325km.  This provides a data highway capacity 20-times higher than current commercially deployed 100Gbit/s systems and has a speed equivalent to downloading 40 HD videos in one second.

Huawei claims that this marks an important step forward for optical transport technology advances beyond 100G. Traffic on carrier backbone networks is growing, driving momentum for commercial 100G deployments and attracting attention on optical transport beyond 100G.

This trial achieved a transmission distance of 1,500 km using a super-channel PDM-16QAM-based high spectral efficiency solution, and a transmission distance of 3,325 km using a super-channel Nyquist PDM-QPSK-based ultra-long-haul solution.

Both transmissions were on a link with G.652 fibers and erbium-doped fiber amplifiers (EDFAs) without electrical regeneration. The link used in the trial was on Vodafone’s 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. 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,” said Jack Wang, president of Huawei’s transport network product line.
