Vietnam Post and Telecommunications (VNPT), the country’s dominant carrier, is using a Nortel optical solution to double the capacity of its national, north-south optical backbone from 20 Gbps to 40 Gbps. The expanded capacity will enable VNPT to provide ADSL to more residential and enterprise customers. The Nortel high-capacity transport solution for VNPT comprises the Optical Long Haul 1600 with the Optical Cross Connect DX for DWDM transport, and the Optical Metro 4000 series of multiservice SDH platforms to enable 10 Gbps connectivity into and from cities along the backbone’s north-south path. Financial terms were not disclosed.

- In 1995, Nortel built the original optical backbone – the country’s first optical DWDM network at 2.5 Gbps – running from Hanoi in the north to Ho Chi Minh City in the south with interconnections into the national network for major cities along the route. In 2003, Nortel upgraded the national backbone to 20 Gbps.
