Garmin NMEA 2000® Backbone/Drop Cable - 12' (4M) - *Case of 5*

The Garmin NMEA 2000® Backbone/Drop Cable – 12' (4M) is the professional-grade connectivity solution serious anglers and boat operators rely on to expand their marine electronics network. Whether you're integrating multiple fish finders, GPS chartplotters, AIS transceivers, or autopilot systems, this backbone cable serves as the arterial infrastructure that ties your entire glass cockpit together. Available in a case of five units, it's the economical choice for charter operations, commercial fishing fleets, or multi-vessel owners who demand reliable NMEA 2000® standards-compliant wiring.

Built to Garmin's exacting marine standards, the Garmin NMEA 2000® Backbone/Drop Cable features shielded, twisted-pair construction that ensures noise-free data transmission between devices even in electrically noisy engine rooms and high-vibration environments. The 12-foot length provides flexibility in routing cables through hull structures, behind panels, and along cabin bulkheads without sacrificing signal integrity. Fully waterproof connectors and UV-resistant insulation withstand saltwater spray, fuel vapor, and years of direct sunlight exposure—critical durability factors for both freshwater and offshore applications.

This cable works seamlessly with Garmin AIS 300/600 Blackbox Transceivers, GBT 10 modules, and other NMEA 2000®-compatible marine electronics, making it the standard backbone extension for modern integrated navigation systems. Installers and boat builders favor this product for its plug-and-play reliability and compliance with open NMEA 2000® protocols. The five-cable case minimizes per-unit cost while providing spares for maintenance, system upgrades, or bulk fleet installations on commercial vessels.
