The Hydromea LUMA 100 optical node 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. It also serves as an ideal replacement of electrical wet mate connectors, making the job of an ROV pilot much easier and faster. This makes it the perfect choice for wireless interfacing between ROVs/AUVs and deep sea instruments.

It is extremely energy efficient, which makes it ideal for battery-powered applications. It can be configured to enter a sleep mode after a specified time of inactivity, and optically woken up from sleep by another modem when the link is re-established.

The software-configurable serial cable interface can be set to RS232 or RS485, which makes the LUMA 100 the ideal dropin replacement for cabled connections in many existing systems.
