Telstra and Ericsson celebrate successful trial of 1Tbps optical link

18 Mar 2013

Australian fixed line incumbent Telstra has successfully carried out its first trial of 1Tbps technology in partnership with Swedish vendor Ericsson. In a press release revealing the achievement, Ericsson noted that the speeds – which it claims are the fastest ever offered over an optical connection in Australia – had been achieved over 995km of an existing fibre-optic network. Commenting on the development, Telstra Director Transport & Routing Engineering, David Robertson said: ‘We are currently upgrading our optical transmission networks with Ericsson’s next generation 100Gbps technology and this trial demonstrates that the higher 1Tbps speeds are possible … 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 fibre cables when required.’

The news comes just a few weeks after Ericsson revealed at the Mobile World Congress in Barcelona that it had been selected to provide Telstra with its next generation optical technology to expand the capacity of the telco’s metropolitan, regional and inter-capital long-haul optical networks. Ericsson will provide metro optical equipment, with the SPO 1400 family and the MHL3000 for long-haul applications, including support for 100Gbps services, using solutions including ROADM (Reconfigurable Optical Add Drop Multiplexer) and DWDM (Dense Wavelength Division Multiplexing) technology with Multiservice DWDM and Packet Optical Transport Platform (POTP) equipment.
