Huawei, a leading global information and communications technology solutions provider, and Vodafone have announced that they have successfully completed 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. This marks an important step forward for optical transport technology advances beyond 100G.

Traffic on carrier backbone networks is growing exponentially, driving global momentum for commercial 100G deployments and attracting attention on optical transport beyond 100G. Riding on cutting-edge technologies such as flex oDSP, super SD-FEC, and flex modulation format, this field trial achieved a record-breaking transmission distance of 1,500 km using a super-channel PDM-16QAM-based high spectral efficiency solution, and a second record-breaking 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.

"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.
