[1] NMEA OneNet is a latest standard[5] for maritime data networking based on 802.3 Ethernet, and will complement existing onboard NMEA 2000 networks by allowing for high-capacity data transfers.
[6][7][8][9] 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,[11] but the full capabilities do not have to be utilized, and would also depend on the cabling that is installed.
