Maretron NBE100 Network Bus Extender
The Maretron NBE100 Network Bus Extender is positioned as a best-in-class option for electrically isolating and extending NMEA 2000 backbones using standard Ethernet cabling, letting installers separate power domains to mitigate ground loops and surge propagation. It outperforms simple tee-and-terminator approaches by providing robust galvanic isolation and long-distance reach at a price point that is often more economical than specialty fiber solutions, making it a strong choice where both protection and backbone extension are required.
