Infinera Selected by MedNautilus for Mediterranean Subsea Network

Fourfold Increase in Undersea Capacity

Sunnyvale, CA on 1 March 2011

Infinera (Nasdaq: INFN) has been selected by MedNautilus to upgrade its subsea network for the speed of deployment and scalability of the Infinera submarine solution.

MedNautilus, the Mediterranean operations of the Telecom Italia Sparkle Group and the first and only protected submarine ring-configured backbone in the Mediterranean, operates a subsea link between Israel and Cyprus as part of a larger submarine cable network connecting the eastern Mediterranean to Greece, Turkey, Italy and France that serves the growing capacity needs of the region.

The Infinera network has enabled MedNautilus to quadruple capacity on its network. It has also delivered benefits in terms of simple operation and speed of deployment, with the network upgrade completed in less than half the time a traditional subsea network would have required. The small footprint of the Infinera equipment consumes significantly less space than traditional submarine optical networking systems. A more efficient use of space represents an increasingly important factor with escalating bandwidth demand requiring more and more equipment at each landing station.

“As a submarine cable operator I would like to see the industry moving to upgrades which are simple to implement, scalable, and plug-and-play as much as possible. Infinera’s solution based on photonic integrated circuits is a move in that direction,” commented Luigi Sangiorgio, Head of Engineering, MedNautilus Network.

“Infinera has seen growing acceptance from the submarine network market segment and we are very pleased to support MedNautilus and help them meet their growing needs for bandwidth in the Mediterranean,” said Infinera president and CEO Tom Fallon. The Infinera DTN as SLTE (submarine line terminating equipment) provides a set of application-optimized features for upgrading submarine cable networks, including support for high-reliability trans-oceanic optical transmission, low-cost and low-latency full-band dispersion compensation optimized for greatly reduced size, integrated low-cost terrestrial backhaul and submarine network inter-connection, and undersea cable connectivity solutions optimized for operating over existing cable systems. Infinera Submarine Solutions have been deployed worldwide for customers for a total of more than 85,000 route-kilometers, including routes across the Atlantic, between North, Central, and South America, in the Middle East, and in the Indian Ocean.
