Ciena was selected in October 2006 to upgrade and expand Interoute's Eastern European network.  The upgrade included Ciena’s CoreStream® Agility Optical Transport System and ON-Center® Network and Service Management Suite to dramatically improve Interoute’s cost of delivering voice, video and data services to its growing customer base across Central and Eastern Europe.

The new contract built on Ciena’s six-year relationship with Interoute, including previous deployments of the CoreStream platform as well as the CoreDirector® optical switch.
