The Hydromea LUMA 500ER optical modem combines outstanding performance and energy efficiency in a very compact form factor. Optical communication offers superior data rates, low latency and lower power requirements compared to acoustic modems. This makes it the perfect choice for applications such as wireless video transmission, data download from submerged sensors and data loggers, as well as wireless interfacing between ROVs/AUVs and deep sea infrastructure.

The LUMA 500ER has an outstanding communication range on a very low power budget. The maximum range is achieved in dark conditions (night time, or deep sea) and clear water.

The software-configurable serial cable interface can be set to RS232 or RS485, which makes the LUMA 500ER the ideal drop-in replacement for cabled connections in many existing systems.
