Ancor NMEA 2000 Backbone Cable – 6.5 ft (2 m) | 270002

Extend Your NMEA 2000 Network with Confidence

The Ancor NMEA 2000 Backbone Cable (6.5 ft / 2 m) is the backbone of a reliable onboard digital network. Designed to connect directly to NMEA 2000 Tee Connectors, this cable carries power and data to every device on your network — from chartplotters and depth sounders to VHF radios and engine monitors. The distinctive yellow couplers mate precisely with Ancor tees, making installation straightforward and connections secure.

Built with large 18 AWG power conductors, this cable minimizes voltage drop across the backbone — a critical factor for maintaining stable, error-free communication on longer network runs.

Key Features

• 6.5 ft (2 m) backbone cable — ideal for mid-run extensions
• 18 AWG power conductors for reduced voltage drop and improved reliability
• Yellow-coded couplers for quick, error-free connection to Ancor tees
• NMEA 2000 certified — compatible with all N2K-compliant devices
• Rugged marine-grade construction for long-term reliability aboard

Compatible Applications

• Chartplotter and multifunction display (MFD) networks
• Depth sounder and fishfinder integration
• VHF radio DSC connectivity
• Engine and fuel monitoring systems

Parts Desk Insights

Best use case: This 6.5 ft (2 m) length is the most versatile backbone segment — long enough to span typical helm-to-helm or helm-to-engine bay runs, and short enough to keep routing clean. It's the go-to choice for mid-run extensions when a 1.6 ft segment is too short and a 16 ft segment would create excess slack. Pair with a tee connector at each end and terminate the backbone with both a female and male terminator for a properly terminated network. If you're starting from scratch, consider the Single Device Backbone Starter Kit which includes the essential components.
