NMEA OneNet

NMEA OneNet is the latest standard
for maritime data networking based on 802.3 Ethernet, and will complement existing onboard NMEA 2000 networks by allowing for high-capacity data transfers.
Current maritime data networks have bandwidth capacities of less than 1 Mbit/s. Building on Ethernet, OneNet allows for capacity in the hundreds or thousands of megabits per second. This extra bandwidth is needed for transferring unprocessed sensor data from sonar/radars, as well as video feeds from for example an engine room.
The primary features and goals of OneNet are as follows:
The use of the X-Coded M12 connector allows for up to 10 Gigabit Ethernet, but the full capabilities do not have to be utilized, and would also depend on the cabling that is installed.
