New Optical Modem for Subsea Communication

Aquatec Group has announced the launch of the AQUAmodem Op1L, a new lightweight version of their standard optical modem, designed for use by divers and on small ROVs.


Using established technology, the optical modem allows short range interrogation, commanding and data download from underwater equipment. The new instrument is three times lighter than the original optical modem, making it ideal for applications in oceanographic, environmental and coastal research, as well as offshore energy industries.

The AQUAmodem Op1L is compatible with any instrument with an RS232 serial interface, including Aquatec’s AQUAlogger and HYDROlog ranges, and can replace costly ROV mateable connectors or cables, resulting in economical operations and greater flexibility. The latest version is also interchangeable with Aquatec’s original optical modem, and can reduce expenditure costs when combined with existing systems.

There is a growing demand for smaller ROVs for shallow water applications, which can be easily deployed from a small boat or dockside. The compact, lightweight design makes the AQUAmodem Op1L ideal for deployment on these ROVs to depths of 500m.

Managing Director, Andy Smerdon, said “Aquatec Group has been producing underwater modems for over a decade. The growth of portable ROVs has sparked a need for a lighter instrument that can be used in shallower waters. The AQUAmodem Op1L allows us to fulfil this demand and provide our customers in the oceanography and environmental sectors with a cost-effective solution for subsea communication.”

Aquatec will be showcasing the new AQUAmodem Op1L at Oceanology International 2016, along with their new AQUAscat 1000L and SSC converter software. If you want to learn more about the optical modem, join Aquatec on stand J300 or visit their website.
