BlueComm is a through-water wireless optical communication system, developed to transmit subsea data, stream video and perform tetherless vehicle control at very high speeds. The BlueComm modem family is currently made up of three variants. BlueComm 100 is optimised for shallow water ‘high ambient light’ operating environments and offers a good balance between data rate and range. BlueComm 200 sends data at up to 10 Mbps and is suitable for deep or night time operations. BlueComm 200 UV is best suited for ROV or AUV applications that require the use of artificial lights, for example, when recording video. The dual laser configuration of BlueComm 5000 supports data transfer rates of up to 500 Mbps.

BlueComm uses the electromagnetic spectrum rather than acoustic pressure waves to transmit high volumes of data. Typically operating in the 450 nm Blue Light region of the spectrum, BlueComm can achieve data rates of greater than 500 Mbps. Optical data transmission is highly efficient, enabling 1 Gb of data to be transmitted with the energy contained within a single lithium D-sized cell over distances greater than 150 metres.
