Aussie Terabit optical link trialled by Ericsson and Telstra

Capacity increase coming up.

Ericsson and Telstra have conducted a successful field trial for 1 Tbps data transmissions, using existing cable plant and alongside 40 and 100 gigabit per second channels on the same fibre.

The trial was done over the past few weeks and covered a distance of 995 kilometres with 1 Tbps line cards and the Marconi MHL 3000 dense wavelength division multiplexing platform, Ericsson noted in a statement.

The trial was done with test data and not live customer traffic on Telstra's network between Sydney and Melbourne, according to a report by Commsday.

"The trial has proven that our existing optical cable plant can support Tbps channels along with 40Gbps and 100Gbps channels simultaneously on the same fibre, verifying that we have the ability to increase capacity on our existing fiber cables when required," Telstra's director of transport & routing engineering, David Robertson, said in a statement.

Optical data transmissions are becoming increasingly faster as capacity demand rises.

In September last year, Japan's Nippon Telegraph and Telephone Corporation announced that it had managed to transmit data at 1 petabit/s speed, or 1000 terabit/s together with partners Fujikura Ltd, Hokkaido University and the Technical Unversity of Denmark.

The trial transmission used a single strand of optical fibre with twelve light paths and 222 wavelength channels over a length of 52.4 kilometres.

NTT said the successful 1 Pbps transmissions is a new world record, over three times as fast as previous tests.

According to NTT, the speed achieved is the equivalent of sending 5000 high definition TV videos.
