High-performance submarine line terminal equipment for next-generation optical submarine cable system: FLASHWAVE S650

Global telecommunications traffic is rapidly growing in response to customer demand for broadband services and more reliable network performance. Thus, the demand for a submarine telecommunications system, which is a backbone infrastructure for international telecommunications, is also steadily increasing. This demand is not only for constructing a new cable system, but also for upgrading capacity by adding extra capacity to existing systems. To meet this demand, we have developed the FLASHWAVE S650, new Submarine Line Terminal Equipment (SLTE), by applying cutting-edge DWDM optical technologies. This equipment features excellent transmission performance, improved maintainability, and a flexible configuration suitable for a long-haul system, coupled with upgraded capacity. The FLASHWAVE S650 was successfully deployed in a SEA-ME-WE 4 cable system and certain upgraded systems. This paper describes the various functions, characteristics, and configuration of the FLASHWAVE S650.
