Overview

The Simrad 000-14376-001 is a 2 m (6.5 ft) NMEA 2000 Micro-C medium duty network cable for extending a backbone run between network components. It uses low-loss 18-gauge conductors, which helps keep signal strength up when you need a longer span than a short jumper.

Use it to link Micro-C tees, power insertion points, and terminators when you are stretching the backbone from the helm to a console, flybridge, or aft station. It is also a straightforward way to avoid stacking joiners and extra connection points in wet or high-vibration areas.

Key features

• 2 m (6.5 ft) length for backbone extensions between NMEA 2000 Micro-C network components
• Low-loss 18-gauge cable specified for network backbone runs
• Micro-C connector ends to match standard NMEA 2000 tees, terminators, and power nodes
• Medium duty construction suited to typical onboard routing through cable chases and consoles
• Helps keep a backbone layout clean by reducing the need for additional couplers

Compatibility and fit

This cable is for NMEA 2000 networks that use Micro-C connectors. It is not a substitute for a device drop cable that runs from a tee to an individual instrument, and it is not used for NMEA 0183 wiring.

If your boat has a mix of connector styles, confirm that every component on the run you are extending is Micro-C on both sides, or plan for the correct adapter at the transition point.

Installation and setup

Route the cable so it stays supported and protected from chafe, and avoid tight bends near the connectors. Keep it clear of high-current power runs where possible, and leave a small service loop so network tees and devices can be moved for troubleshooting.

Hand-tighten the locking collars fully so the connection stays seated in a wet environment, and place the run where you can still access it if you need to add a tee or isolate a segment later.

Use cases on board

This length is commonly used when a backbone needs to span between helm electronics and another station, or when you are adding NMEA 2000 devices farther away from the existing network cluster. It suits boats that are expanding a network to carry engine data, heading, AIS, autopilot, or sensor information across multiple displays.

Maintenance and care

Periodically check that the connectors remain snug and free of salt buildup, especially in exposed consoles and under-deck lockers. If you ever disconnect the network, keep the connector ends clean and protected until everything is reassembled.
