Ancor NMEA 2000 Backbone Cable – 16 ft (5 m)
Extend or build out your onboard NMEA 2000 network with confidence. This 16-foot (5 m) backbone cable from Ancor is engineered for the demanding marine environment — delivering clean, reliable data communication between your chartplotters, depth finders, VHF radios, and other NMEA 2000-compatible devices.
The distinctive yellow couplers mate directly with Ancor NMEA 2000 tee connectors, making network assembly straightforward and mistake-proof. Heavy-gauge 18 AWG power conductors minimize voltage drop across the backbone, keeping your network stable even on longer runs.

Parts Desk Insights
This cable is best suited for mid-length backbone runs where you need a reliable, pre-terminated segment without custom cutting or crimping. It's a go-to choice when expanding an existing NMEA 2000 backbone or replacing a damaged segment. For shorter runs, consider the 1.6 ft or 6.5 ft backbone cables. For longer runs, see the 32 ft (10 m) backbone cable. Always terminate both ends of your backbone with male and female terminators for proper network operation.
