What is the maximum backbone length for Lite cables?

• A. 250 m
• B. 100 m
• C. 50 m
• D. 300 m

Answer: (B)

Lite cables are more lossy than standard backbone cable, with higher attenuation and capacitance per meter. Because the backbone must carry the NMEA 2000 signal with enough voltage and proper timing across the entire trunk, this increased loss limits how far the signal can travel reliably. To keep signal integrity and timing within the spec, the backbone length is capped at about 100 meters when using Lite cable. If you need longer runs, use standard backbone cable or redesign the network with shorter segments and proper terminations to stay within electrical limits. So, the maximum backbone length for Lite cables is 100 meters.
