Fujitsu wins China WDM contract

Fujitsu has won an order from a Chinese city government for a WDM (wave division multiplexing) system valued at 1 billion yen ($US8.2 million), the company said yesterday.

Under the terms of the deal, the Post and Telecommunications Bureau of Zhangzhou City in Fujian Province will buy a 546 km-long public network for voice and data traffic, a Fujitsu spokesman said.

The network will use WDM technology, which expands the capacity of optical fibre by enabling it to carry multiple signals over individual fibres. The Fujitsu system will support 16 channels, each with a capacity of 2.5Gbits per second, or a total capacity of 40Gbit/sec.

Tokyo-based Fujitsu is also involved in undersea WDM projects linking Australia to Singapore and a cable linking New Zealand, Japan and the US, known as the Southern Cross submarine cable project.
