TeliaSonera International Carrier employs Ciena for Pan-European network upgrade

TeliaSonera International Carrier (TSIC) has tapped Ciena as the optical vendor of choice to upgrade the pan-European segment of its global fiber network, enabling it to expand its portfolio of 1-100G services to its wholesale service provider customers.

Ciena has been chosen for its Pan-European network while Infinera's DTN-X platform is being used for its U.S. network route.

For this latest upgrade, the service provider is using Ciena's 5400 Reconfigurable Switching System. TSIC said that the platform will enable it to simplify its network infrastructure by converging SDH, Ethernet and OTN so it can deliver 1G to 100G optical services to its growing wholesale customer base of 1,000 content, operator and traditional service providers.

TSIC has continued to build out its own 100G-enabled, fiber network with 200 PoPs worldwide. Over the past two years, the service provider has been aggressively upgrading its network infrastructure in both Europe and the United States.

The European 100G network is based on Nokia Siemens Networks--now Coriant's--hiT 7300 platform, while the U.S. network is based on Infinera's DTN-X platform. Serving a mix of traditional carriers and content providers that are furthering their presence in North America, TSIC's U.S. network is based on fiber purchased from WilTel in the late 1990s. In 2009, TSIC deployed Infinera's DTN platform to provide 1 Gbps and 10 Gbps wavelength services.

Besides upgrading its network gear, the service provider has been expanding the reach of its dark fiber network. By adding 11,500 dark fiber miles to its network in November 2013, TSIC will extend its reach into 44 American cities by the end of this year.
