Description

The Hydromea LUMA 500ER optical modem combines outstanding performance and energy efficiency in a very compactform factor. Optical communication offers superior data rates, low latency and lowerpower requirements compared to acoustic modems. This makes it the perfect choice for applications such as data download from submerged sensor platforms (landers), as well as wireless interfacing between ROVs/AUVs and deep sea infrastructure. Compared to the LUMA 250LP it offers a much greater transmission range.

The LUMA 500ER is very energy efficient, which makes it ideal for battery-powered applications.

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.

Features:

Ultra-compact and low weight, ideal for small ROVs/AUVs
Four transmission power levels: 2 - 5 W
Wide supply voltage range
Encryption of data link, ad-hoc networking (optional, on request)

Applications:

Wireless readout of landers and subsea infrastructure with ROV/AUV
Low power communication for battery-powered underwater devices
Wireless video streaming for mini ROVs
Subsea networks at deep sea sites
