Simrad NMEA 2000 Medium Duty Backbone Micro-C Cable

The Simrad NMEA 2000 Medium Duty Backbone Cable is a premium, marine-grade networking cable built for creating stable and efficient NMEA 2000 systems on board. As part of the trusted Simrad (Navico) lineup, this genuine cable delivers seamless, high-speed data transfer between devices such as chartplotters, fishfinders, radars, autopilots, sensors, and engine interfaces from Simrad, Lowrance, B&G, and other NMEA 2000-compatible brands.

Why Choose This Cable?

A properly designed NMEA 2000 network is the backbone of modern marine electronics, delivering real-time data sharing for navigation, engine monitoring, instrumentation, and safety features. The medium-duty design with thicker 18 AWG conductors reduces signal loss, helping maintain reliable performance even on larger boats or setups approaching the 100m total backbone limit for Micro-C cables. Easy plug-and-play installation with drop cables, T-connectors, and terminators (sold separately) makes expanding or upgrading your system straightforward.Important

Note: For optimal network performance, follow NMEA 2000 guidelines—use terminators at both ends of the backbone, limit total length, and avoid excessive drops. This cable is the official Simrad recommendation for reliable backbone connections.

Features

• Compatibility: NMEA 2000 certified; plug-and-play with Simrad, Lowrance, B&G, and any Micro-C equipped NMEA 2000 devices
• Durability: Engineered for harsh marine conditions - resistant to saltwater corrosion, UV exposure, moisture, and onboard vibrations
• Provides a more robust and stable network compared to light-duty cables, especially in systems with multiple devices or longer total backbone lengths
• Primarily for network backbone runs (main spine of your NMEA 2000 network); can also serve as extensions where needed

Specifications

• Available Sizes: 2 m (6.5 ft.), 6 m (19.7 ft.), 10 m (33 ft.)
