Ericsson and Telstra run world’s first live 40Gbps optical transmission trial in Australia

May 25, 2007, 08:30 (CET)

Ericsson (NASDAQ:ERIC) and Telstra have successfully completed the world’s first live network trial for next-generation 40Gbps optical transmission technology in Australia.

The technology trial demonstrated that Telstra’s existing 10Gbps Dense Wave Division Multiplexing (DWDM) transmission technology, which carries voice, data and video, can be increased to 40Gbps without major changes to the network.

Dan Burns, Telstra Executive Managing Director, Network and Technology said: “This trial was commissioned as a part of Telstra’s forward planning to meet expected growth on the inter-capital networks. It demonstrates the capability of the Telstra Next IP(TM) network and effectively positions Telstra at the forefront of industry development to implement high capacity long distance transmission.”

“Enabling 40Gbps connections between Telstra’s IP core routers, will allow us to expand our network capacity in line with expected growth in IP traffic,” added Mr Burns.

The trial was conducted over Telstra’s existing 10Gbps 1,121 km coastal and 1,244 km inland optical fiber routes from Sydney to Melbourne.

Bill Zikou, CEO, Ericsson Australia and New Zealand, explained the trial was conducted over a 10Gbps network with no modification to the existing optic fiber infrastructure.

“Ericsson’s DWDM solution, Marconi MHL 3000, provides a seamless in service upgrade of capacity with minimal investment. This means that with Ericsson they would have no need to change the existing optic fiber infrastructure,” he added.

The ability to offer an extremely scalable, high capacity optical solution enables network operators to respond to expected bandwidth increases caused by new and exciting consumer (Residential, Mobile and Business) packet-based Full Service Broadband applications.

Ericsson’s next-generation 40Gbps optical transmission technology is based on the new modulation format which exhibits high robustness against PMD (Polarization Mode Dispersion - a fiber characteristic which can limit high-speed transmission).

Ericsson has provided Telstra’s transmission infrastructure in Australia for several years. The infrastructure is part of the Telstra Next IP(TM) network providing the connectivity between major Australia cities and where it integrates with more recently implemented technology provided by other Strategic Suppliers.

Ericsson is shaping the future of Mobile and Broadband Internet communications through its continuous technology leadership. Providing innovative solutions in more than 140 countries, Ericsson is helping to create the most powerful communication companies in the world.
