Last week Chinese telecoms equipment vendor Huawei said that it had successfully completed a field trial using optical fiber transmission technologies on Vodafone’s live network. The company claimed it reached 2 Tbit/s transmission capabilities over 3,325 km, or 2066.059 miles. This capacity is essentially twenty times higher than current commercially deployed 100 Gbit/s (100G) systems, Huawei said.
The field trial achieved a "record-breaking" transmission distance of 1500 km (932 miles) by using a super-channel PDM-16QAM-based high spectral efficiency solution. The company then broke another record by achieving a transmission distance of 3,325 km (2066 miles) using a super-channel Nyquist PDM-QPSK-based ultra-long-haul solution.
According to Huawei, both transmissions were on a link with G.652 fibers and erbium-doped fiber amplifiers (EDFAs) without electrical regeneration. The company added that 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.
