What can be up to 100 meters in length on a NMEA 2000 backbone?

• A. It can be up to 100 meters in length
• B. It can be up to 50 meters
• C. It can be up to 200 meters
• D. It cannot be used for NMEA 2000 backbones

Answer: (A)

On a NMEA 2000 network, the backbone is the main trunk that carries the data to all devices. The standard specifies that this backbone can be up to 100 meters long, which helps ensure reliable CAN bus signaling at the network speed. Devices connect to the backbone with shorter drop cables, and the ends of the backbone must be terminated with 120-ohm terminators. If you need more distance, you’d redesign within the standard’s guidelines to stay within the 100-meter backbone limit.
