What gauge is used for the signal pair on Heavy NMEA 2000 cable?

Explanation:
The signal pair on Heavy NMEA 2000 cable uses 18 AWG conductors. This size is chosen to meet the CAN bus requirements used by NMEA 2000: it provides a good balance of low resistance to minimize voltage drop and attenuation, while still being flexible and cost-effective for marina- and boat-length runs. The 18 AWG pair helps maintain the proper signal integrity for the CAN High and CAN Low lines, which operate with a characteristic impedance in the bus topology. Using a thicker gauge would add stiffness and cost without tangible benefits for the CAN signaling, while a thinner gauge would raise resistance and make the network more susceptible to noise and data errors.
