Le modem optique Hydromea LUMA 250LP: modem optique ultra-performant offrant des performances exceptionnelles pour les applications marines!
SVP contactez Marine Distribution & Consulting pour plus d'informations!
The Hydromea LUMA 250LP 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 data download from submerged sensor platforms (landers), as well as wireless interfacing between ROVs/AUVs and deep sea infrastructure.
Do not hesitate to contact us for all further information requests!
The LUMA 250LP is very 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 LUMA250LP the ideal drop-in replacement for cabled connections in many existing systems.
