The largest service provider in Vietnam, Vietnam Telecoms National (VTN), has successfully completed a next-generation 100 Gigabit per second network trial on its backbone network. The trial, conducted with network specialist Ciena Corporation, demonstrates the operator’s ability to leverage its existing network assets in order to cost-effectively upgrade its nationwide core backbone network as bandwidth demands continue to increase.
Conducted in February 2011, the trial spanned 500 kilometres between the cities of Vinh and Danang, and follows the recent deployment of Ciena’s coherent 40G solution across VTN’s nationwide optical backbone. Using the ActivFlex 6500 Packet-Optical Platform, VTN was able to add coherent 100G lines to its in-service network with no re-engineering of existing fibre routes or additional equipment required.
“The successful trial of coherent 100G technology on our network provides us with a seamless upgrade path from 10G and 40G to 100G to accommodate the growth of high-bandwidth services like IPTV, broadband Internet, 3G mobile traffic and Ethernet business services,” said Luong Manh Hoang, managing director of VTN. “With plans to more than double our network capacity during the next few years, Ciena’s solution provides a painless evolution path to 100G through the use of proven coherent optical technology and extensive field experience, giving us confidence that we can continue to grow the total capacity of our backbone network today and into the future as demand requires.”
