Neptune Underwater Communications

Neptune-Testing-at-San-Diego-Harbor

Neptune is a low-power, compact, high data rate system for underwater communications and data transfer in both littoral and deep ocean environments. Optical communications can provide significant benefits when transmitting data underwater, including substantially higher data rates, reduced loiter time, and increased stealth and safety.

Neptune consists of a flexible laser transmitter that provides adaptive modulation capability based on water conditions and link distance. Coupled with a highly sensitive optical detection system, Neptune offers a very robust and reliable communications link. Data rates up to 250 Mbps at distances up to 200 meters are supported, depending on water turbidity.

Neptune is also equipped with SA Photonics’ innovative BeamDirector system for full hemispherical beam steering and high bandwidth closed loop beam tracking to accommodate reliable communications in the presence of platform vibration and movement, even in rough seas. Acquisition between two nodes is automated so that operation is simple and fast.
