Benthos underwater acoustic modems for subsea wireless communications

Benthos Underwater Acoustic Modems

Benthos acoustic modems provide wireless underwater data transfer for offshore and marine operations, enabling communication between subsea assets and the surface or directly among underwater platforms without relying on physical cabling. The product family supports long-range acoustic links that help reduce installation complexity while offering adaptable deployment options through self-contained and OEM configurations. Flexible housing designs, multiple transducer choices—including integrated or remote, omnidirectional or directional variants—and compatibility with the Janus interoperability communication protocol allow the systems to be tailored for a broad range of subsea missions. Optional functionality such as high-capacity data logging, in-band acoustic recording, arbitrary waveform playback, and dual serial ports further extends operational flexibility.

Designed for environments ranging from shallow coastal waters to deep-ocean deployments, the Benthos modem portfolio includes solutions with varying depth ratings, power configurations, operating frequencies, and communication performance to address different mission requirements. Depending on the selected model, the systems support both higher-throughput transmission and lower-rate, reliability-focused communications. OEM offerings enable integration into underwater vehicles and custom subsea packages, while interoperability with Benthos positioning and acoustic release technologies supports unified underwater system architectures where coordinated communications and localization are required.
