Infinera Deploys Transatlantic Route for Major Global Telecommunications Service Provider

Increased space and power savings in minimal deployment time

Sunnyvale, CA on 20 May 2010

Infinera (Nasdaq: INFN) has successfully deployed a transatlantic route of over 6,000 kilometers for a major global telecommunications service provider. The new route provides the service provider 1.76 Terabits/second (Tb/s) of optical capacity on a single fiber pair.

The Infinera Submarine Solution uses Infinera’s double-density technology to enable wavelengths to be implemented on a 25 Gigahertz channel grid, providing for doubling the density or capacity compared to traditional DWDM optical systems implemented on a 50 Gigahertz channel grid.

Based on the Infinera DTN, the Infinera Submarine Solution is designed to offer end users numerous significant benefits over traditional submarine systems. In addition to increasing capacity, the Infinera solution is intended to enable a submarine service provider to deliver new services while simultaneously increasing the space and power efficiency of the land-based submarine system. An innovative dispersion management solution is engineered to simplify dispersion management.

With its Digital Optical Networks architecture based on photonic integrated circuits, the Infinera Submarine Solution is intended to enable quick and easy deployment, provisioning, and management of the network, often reducing the time it takes to add new services to the system from months to days.

Infinera has enjoyed market success since launching the Infinera Submarine Solution last year. The Infinera system is designed to enable service providers to accommodate demand growth without the need to invest in their subsea infrastructure. Infinera’s Submarine Solution has already been deployed in submarine networks in North America, the Caribbean, and South America.

“We believe that Infinera is an ideal solution for those subsea service providers seeking to update their plant and increase their capacity without incurring large capital expenditures,” said Mike Guess, Infinera Vice-President of Network Architecture. “With the completion of this project, the Infinera Submarine Solution is now deployed on over 50,000km of submarine cable systems.”
