VNPT upgrades national backbone with Nortel equipment

24 May 2007

Vietnam Post and Telecommunications (VNPT), the country’s state-owned incumbent, has contracted Canadian vendor Nortel to double the capacity of its national optical backbone and meet accelerating demand for high-bandwidth video, mobile, and broadband services. By upgrading its 3,000km north-south optical transmission network to 40Gbps, VNPT says it will be able to provide ADSL broadband access to more customers, handle increased mobile traffic for wireless operators and create a platform for its planned migration to a wholly IP-based infrastructure. Nortel built the original optical backbone in 1995. It was at the time the country’s first optical dense wavelength division multiplexing (DWDM) network, running from Hanoi in the north to Ho Chi Minh City in the south with a capacity of 2.5Gbps. In 2003 Nortel upgraded the national backbone to 20Gbps. According to TeleGeography’s GlobalComms database, VNPT had half of the wireline market at the end of 2006, with just under eight million subscribers.
