Know before you buy
Yes, this is a standard Micro-C NMEA 2000 backbone cable. It is designed to integrate seamlessly with any marine electronics network that follows the NMEA 2000 connectivity standard.
This cable is specifically recommended for backbone runs. Its medium-duty, 18-gauge wiring is optimized to maintain signal integrity over longer distances within your network infrastructure.
The orange locking collars are a visual identifier used by Navico to help you quickly distinguish backbone cables from shorter drop cables or other network components during installation and troubleshooting.
The cable is engineered for low-loss performance, ensuring reliable data transmission across its full 20-meter length. As long as your total NMEA 2000 network backbone does not exceed the maximum recommended length for the system, this cable will perform reliably.
This cable uses UTP (Unshielded Twisted Pair) construction. While it is built for robust marine use, it is best practice to route it away from high-voltage power cables to minimize potential electromagnetic interference.
