Emergency Alternative EDFA system

Telecommunication systems are vitally important in our daily lives, even more so during the rescue and recovery processes upon natural disasters, such as the earthquake hitting the east-coast of Japan in 2011. The deadly earthquake rattled the nation coast before unleashing a deadly tsunami that swept away cars, homes and businesses as it touched land. The communication infrastructure was among the victims. Rapid rebuilding of the telecommunication system becomes an absolute priority.

Amonics’ Emergency Alternative EDFA system is a hand-held battery-powered Bi-directional Packet Switching DWDM EDFA module. It is designed for instant reconnection of fractured telecommunication system under emergency conditions. This all-in-one EDFA device features long operating time, lightweight and waterproof (IP66) casing.
