4 reasons you should be using optical modems
Optical modems give you a wireless connection to your instrumentation underwater as if you had a cabled connection to a PC at the surface. This highly powerful tool means you can check your instrument is working, change the settings, collect data and reprogramme them for the next deployment – not bad for one piece of kit! Suitable for divers or ROVs to use, let’s explore further…
1. Check your instruments are working
So you’ve deployed your instruments a few hundred (or thousand) metres deep and you’re about to leave them for a month – wouldn’t it be good to check they are set up and functioning correctly? Connecting to the instrument using your optical modem means you can check the set up and leave them knowing your deployment is starting in the best possible way!
2. Change the settings
If you discover the instruments are not set up correctly when you do a status check, connection with an optical modem is the same as if the instrument is connected to your PC with a cable on your desk. This means you can change the settings subsea without having to bring the whole instrument, frame or manifold to the service, saving you time and money!
3. Access your data subsea
After your deployment or during a service visit, you can download all of the data gathered so far and get a real time view if your instrument is set up this way. New generation Aquatec loggers (HYDROlog 3000 and AQUAlogger 310) even allow you to download while logging! Particularly useful for extended deployments, you can get an immediate view of your data before bringing it to the surface, or access your data part way through a deployment.
4. Reprogramme your instrument
After you have accessed your data, you may decide to change your sampling regime based on data gathered so far to refine your view, explore certain phenomenon further, or improve your resolution. Optical modems allow you to do this subsea without costly retrieval and redeployment.
