FAQs
What is the AQUAmodem® Op2 used for?
The AQUAmodem® Op2 is used for wireless subsea data access, allowing operators to communicate with compatible underwater instruments without recovering them to the surface.
How does the AQUAmodem® Op2 work?
The system uses a pair of optical modems to create a transparent RS232 link through water. One modem remains connected to the subsea instrument, while the ROV positions the second modem to establish the optical link.
Can the AQUAmodem® Op2 download data from subsea instruments?
Yes. The Op2 supports short-range interrogation, control and data download from compatible subsea instruments.
Does the AQUAmodem® Op2 provide real-time communication?
Yes, the Op2 can support real-time remote access to subsea instruments, depending on the connected instrument and deployment setup.
What instruments is the AQUAmodem® Op2 compatible with?
The Op2 is compatible with instruments using RS232 serial interfaces, including Aquatec’s HYDROlog® and AQUAlogger® ranges. RS485 compatibility is available as an option.
What is the depth rating of the AQUAmodem® Op2?
The AQUAmodem® Op2 is depth rated to 3,500 m.
What is the operating range of the AQUAmodem® Op2?
The typical operating range is 1 m to 2 m, depending on environmental conditions.
Is the AQUAmodem® Op2 suitable for ROV operations?
Yes. The Op2 is suitable for work-class ROVs and can support subsea data transfer through the ROV umbilical cable.
