Why BlueComm 200 is perfect for...
Tetherless vehicle operations around complex seafloor infrastructure is now possible thanks to BlueComm 200 with a bi-directional link that's suited for ROV command and control.
There's no need to recover your underwater networks. Covertly harvest large amounts of data fast and efficiently from your surveillance arrays with Bluecomm 200.
BlueComm 200 is ideal for operations such as live video streaming during underwater excursions, opening up science missions to the global audience in real-time.
BlueComm 200 uses an array of high power light-emitting diodes (LEDs) that are rapidly modulated to transmit data. It uses a separate photomultiplier tube as its receiving element. The photomultiplier tube allows sensitive receive capability and communication ranges of up to 150 m.
Due to the sensitivity of the photomultiplier receiver, the emitter is housed separately to prevent self-interference. All BlueComm 200 modems provide subsea wireless optical communications up to 10 Mbps. Two versions of the BlueComm 200 are available, operating at different wavelengths.
The allocation of bandwidths is ideal for applications where high-speed data transfer is mostly required in only one direction such as for extraction of large data volumes from seafloor instrumentation or sensors.
Optical data transmission is highly efficient, enabling more than nine gigabytes of data to be transferred using only the energy contained in a single Lithium D sized battery cell.
BlueComm 200 or BlueComm 200 UV?
BlueComm 200 operates using visible light. Visible light can travel significant distances through water meaning that BlueComm 200 has a range of up to 150 m. This makes it an excellent tool for wireless transfer of video and direct control of a vehicle in AUV applications. It is also ideal for data harvesting applications. Using BlueComm 200, an AUV or ROV can transfer large volumes of data up to ten thousand times quicker than acoustics. Artificial lights and sunlight can interfere with BlueComm 200 and that would limit its operating range.
BlueComm 200 UV works just like BlueComm 200, however it uses a shorter wavelength in the ultra-violet spectrum. This means that it can operate even in the presence of artificial lights. Operating in the UV spectrum, BlueComm 200 UV can work at ranges of up to 75 metres. It is best suited for ROV or AUV applications that require the use of lights, for example, when recording video.
