Furuno LAN Cable Assembly - 5M RJ45 x RJ45 4P

The Furuno LAN Cable Assembly – 5M RJ45 x RJ45 4P is the reliable backbone connecting your Furuno NavNet 3D or TZT chartplotter to your onboard PC or networking system. Whether you're running advanced sonar overlays, route planning software, or multi-unit vessel integration, this 5-meter Ethernet cable ensures clean, uninterrupted data flow between your marine electronics and computing equipment. Every boater or captain managing modern navigation systems needs a properly rated, marine-grade network connection to avoid data loss or communication dropouts during critical moments on the water.

Built to Furuno's exacting marine specifications, this LAN cable features dual RJ45 connectors (4-pair twisted copper conductors) that deliver stable Ethernet protocol communication in the demanding environment of a boat. The 5-meter length (approximately 16.4 feet) provides sufficient reach to route between helm stations, engine rooms, or cabin-mounted displays without requiring splices or adapters that could introduce signal degradation. The shielded construction and industrial-grade connectors resist corrosion, salt spray, and the vibration common to running diesel or gasoline engines, ensuring your network stays live in conditions that would compromise lesser cables.

This assembly is purpose-built for NavNet 3D/TZT users integrating PC-based navigation software, real-time weather overlays, or sonar data logging into their helm setup. Installation is straightforward—simply plug one RJ45 end into your Furuno display unit and the other into your PC or network switch. Replacement or backup cables are essential for extended cruising or commercial fishing operations where network downtime translates directly to lost productivity. OEM Furuno parts like this cable assembly guarantee compatibility and eliminate the risk of using undersized or non-marine-rated Ethernet cables that fail in saltwater environments.
