Optical modems - standard products

AQUAmodem optical modems provide a seamless interface between the user and any subsea instrumentation with RS232 serial interfaces, such as our AQUAlogger oceanographic instruments and HYDROlog hydrotest loggers. The connection is made typically via an ROV umbilical, providing simple use and deployment of the instrument. They feature individual unit addressing and automatic optical or serial data wake-up, to conserve the life of the external battery pack and prolong the service of the device. The instruments permit short range interrogation, commanding, and data download for your subsea monitoring equipment, providing you with a cost-effective and efficient solution to solve your subsea communication needs.

Acoustic modems for real time systems

Subsea acoustic data transmission is a powerful tool, improving efficiency, availability of data and reducing the need for underwater intervention. However, the transmission of acoustic signals subsea is complex and dependent on a variety of environmental factors, including water column structure, bubbles and noise. As a result, Aquatec acoustic modems are not available as off the shelf products. Instead, we work with you to ensure communication success with custom made modems for each project.
