Hydroid BlueWater Optical Modem

The BlueWater optical modem series, often marketed as the LUMA family, represents a significant advancement in subsea communications. Originally developed by Hydroid, Inc., a leader in autonomous underwater vehicle (AUV) technology, these devices utilize light-based signals to transmit data through water at high speeds, offering a wireless alternative to traditional acoustic modems or physical cables. These modems are engineered for extreme environments, with some models rated for depths up to 6000 meters.

The technology behind these optical modems was pioneered through collaborations involving Hydroid and the expertise of Swiss engineering teams. The manufacturing and technical refinement of the LUMA line primarily take place in Switzerland, where precision engineering ensures the reliability required for deep-sea research and commercial offshore operations. This makes them a critical component for modern AUVs and remotely operated vehicles (ROVs) that require high-bandwidth data transfers for real-time video or sensor data.

Today, the brand is under the umbrella of Huntington Ingalls Industries (HII), which acquired Hydroid to strengthen its position in the unmanned maritime systems market. While Hydroid continues to operate as a specialized unit within HII's Unmanned Systems business group, the ultimate corporate oversight and global distribution are managed by HII from its headquarters in the United States. This ownership structure allows the brand to serve both commercial marine industries and international defense sectors.
