Fujitsu Ltd has announced that Vietnam Telecom National will deploy Fujitsu's Flashwave 7500 high-speed optical wavelength division mux as the transmission backbone of its next-generation network. This deployment of the device is the first by a customer in Asia, said the companies.

According to Fujitsu, the Flashwave 7500 series includes a reconfigurable optical add/drop mux (ROADM) for building high-speed optical networks. With Wavelength Selective Switch technology, which makes efficient use of optical signals, the Flashwave 7500 system permits setting and changing optical signal paths by remote operation. ROADM technology provides for cross-connecting, or splitting an unmodified optical signal among multiple paths. This allows for vastly lower power consumption and other operating costs compared to conventional equipment, which requires conversion into electrical signals.

Fujitsu plans to expand the reach of its optical wavelength division multiplexing equipment globally as customers in Asia Pacific, Europe, the Middle East and Africa construct next-generation networks.

Connecting Vietnam
In Vietnam, there has been a sharp increase in demand for next-gen networks due to increasing numbers of mobile phone subscribers. To meet these needs, a trunk-line network capable of handling larger processing volumes has become necessary.

In this connection, the Vietnam Posts and Telecommunications Group has started the construction of a next-generation network. For the new optical trunk-line network in the country's southern region, Vietnam Telecom National, which operates under Vietnam Posts and Telecommunication Group, will deploy Fujitsu's Flashwave 7500 wavelength division mux. This trunk-line network will traverse 3,000km in Vietnam's southern region, linking together the region's 21 provincial capitals. The project is set for completion by early 2009.

Vietnam Telecom National says it selected the Flashwave 7500 series because of its technical sophistication, Fujitsu's strong track record in supplying equipment to Vietnam's telecommunications market, and the technical support to be provided by VNPT-Fujitsu Telecommunication System Ltd, a joint venture between Vietnam Posts and Telecommunications Group and Fujitsu.
