Collection: Network Cables & Modules

Connecting a modern marine electronics suite means working across two main networking standards: NMEA 2000 for sensor data and proprietary Ethernet formats like Garmin's Marine Network. This category covers the cables, splitters, connector kits, and bypass modules that tie those systems together, with products from Furuno, Garmin, Maretron, and SI-TEX. Garmin Marine Network cables run up to 500 feet for large-vessel installs, while Maretron's waterproof Ethernet cable suits shorter exposed runs. AIS splitters from Furuno and SI-TEX let a single antenna feed both a VHF radio and an AIS receiver, though the Furuno splitter is designed exclusively for the FA-30, so verify device compatibility before ordering.

On the NMEA 2000 side, Maretron mating connectors come in 1-meter and 3-meter lead options, so measure your runs before ordering. The 12-circuit bypass modules are offered with or without a fuse pack, which matters depending on whether you are building a new install or expanding an existing network. Before buying, confirm compatibility with your specific chartplotter, fishfinder, or AIS unit, as network formats and connector pinouts are not interchangeable across brands.
