RETN upgrades pan-European fiber-optic network with Infinera DTN-X

Europe-based international network service provider RETN has installed Infinera's DTN-X packet optical transport system on its 30,000-km pan-European network. The deployment will enable RETN to support 100-Gbps transmission via the DTN-X's 500-Gbps superchannels.

RETN's fiber-optic network backbone connects 26 countries across Europe, Asia, and North America. The current deployment focuses on the European portions of RETN's footprint. RETN has been an Infinera customer for the past five years (see "Infinera nets Russian deal").

"RETN's global footprint is growing rapidly due to constantly increasing traffic between different territories on the one hand, and RETN's intention to address our customers' geographical interests and to improve their connectivity between the world's largest telecommunications nodes," explains Anthony O'Sullivan, director at RETN Ltd. "At the moment, the RETN network has a total capacity of 5 Tbps on the four main traffic routes and handles a considerable amount of international Internet traffic. In order to respond to the traffic growth, we need to scale our network, while complying with strict requirements for high-performance WDM equipment.

"We consider Infinera's solution unique as it enables smooth migration toward coherent superchannel technology," O'Sullivan adds. "In addition, the Infinera equipment provides us with the ability to meet strict service level agreement requirements and keep the quality of our services at a high level. For these reasons, we use Infinera's solutions to upgrade and extend the RETN network. One of our latest completed projects -- the launching of a trans-Baltic DWDM route from Finland to Poland through the Baltic cities -- deploys Infinera DTN-X equipment based on 500G superchannel technology."
