ECI Telecom has adapted Raman technology to connect regional and long-haul networks in locations that were previously difficult or expensive to link, while using fewer amplifiers. Raman technology was initially designed for ultra long-haul networks. ECI said its Raman technology enables the connection of regional and long-haul distances without needing inline amplifiers underwater or between distances. This eliminates the need for undersea waterproof amplifiers, reducing costs significantly for the provider. The solution could be used for upgrading the optical fiber infrastructure to carry DWDM between a group of islands. It is already being used in an undersea network in the Philippines. http://www.ecitele.com
