Siemens wins Telstra backbone upgrade contract

Telstra announced yesterday it has selected Siemens to supply telecommunications transmission equipment for its national network expansion project.

Under the three-year contract, Siemens' role includes the design, manufacture, logistics management and technical support of the hardware and software for the synchronous digital hierarchy (SDH) transport system. Wavelength division multiplexing (WDM) is a key component of the contract, officials said.

A spokesperson for Siemens said a key part of the contract is the supply of optical equipment for a new Melbourne to Perth WDM link.

This follows the recent introduction of WDM on Telstra's Melbourne to Sydney optical fibre links, also supplied by Siemens.

"We've identified the need to increase capacity on the Melbourne to Perth link to cater for the increased international call and data traffic routing through Australia," Gerry Moriarty, Telstra's group managing director network and technology group, said.

According to executive general manager of network products at Telstra, Graham Shepherd, the carrier is upgrading its optical networks to cater for increased Internet and data traffic on the main intercapital routes.

" Telstra has introduced leading-edge WDM technology to meet this explosive growth in customer demand.

"The Siemens WDM implementation provides for up to eight separate wavelengths, each capable of carrying 2.5Gbit/sec, to be added to the route," he said.
