Furuno NavNet Ethernet Cable

Enhance Your Marine Network with Reliable Connectivity

In the demanding world of marine navigation, seamless communication between your electronics is crucial for safety and efficiency. The Furuno NavNet Ethernet cable delivers that connection with precision engineering designed for harsh saltwater environments. This 30-meter crossover cable, featuring 6-pin female connectors on both ends, allows direct linking of NavNet-compatible devices like multifunction displays, radars, and sounders without needing additional hubs or switches in many setups.

Whether you're outfitting a fishing vessel, yacht, or commercial boat, this cable ensures high-speed data transfer for real-time chart updates, radar overlays, and sonar integration. Built to withstand UV exposure, moisture, and vibration, it maintains signal integrity over long distances, reducing latency that could mean the difference between spotting hazards early or reacting too late.

Key Features for Superior Performance

• Durable Construction: Shielded twisted-pair wiring minimizes electromagnetic interference from onboard engines and radios, ensuring stable Ethernet performance even in rough seas.
• Crossover Design: Automatically handles the signal crossover needed for direct device-to-device connections, simplifying installation on vessels with limited space.
• Extended Reach: At 30 meters, it bridges gaps between helm stations, antennas, and peripherals without signal degradation, ideal for larger boats.
• Weatherproof Connectors: IP67-rated 6P(F) plugs seal out water and corrosion, supporting Furuno's reputation for rugged marine gear.
• Plug-and-Play Simplicity: No configuration required—just connect and your NavNet network expands effortlessly.

Perfect Compatibility Across Furuno Systems

This cable integrates flawlessly with Furuno's NavNet TZtouch, TZtouch2, and TZtouch3 series, as well as older NavNet vx2 and 3D models. It supports NMEA 2000 and Ethernet-based networking, enabling features like ARPA radar tracking, AIS overlays, and video camera feeds across multiple screens. For hybrid setups, pair it with Furuno's network expanders to create a robust, scalable system that grows with your boating needs.

Captains upgrading from legacy systems appreciate how it future-proofs their investment, maintaining compatibility while unlocking modern capabilities like wireless remote control and app integration.

Easy Installation for DIY or Professional Setups

1. Plan your route: Secure the cable along existing wiring runs or bulkheads to avoid sharp bends and chafe points.
2. Prepare ends: Ensure connectors are clean and dry; apply dielectric grease for extra protection in wet areas.
3. Connect devices: Plug into Ethernet ports on your Furuno units—crossover design handles MDI/MDIX auto-sensing.
4. Power cycle: Restart connected devices to establish the link; check network status on your display menu.
5. Test thoroughly: Verify data flow with radar sweeps, GPS fixes, and depth readings across the network.

Pro tip: Use cable ties and conduits for a tidy install that complies with ABYC standards, making future maintenance a breeze.

Why Boaters Trust This Cable for Long-Term Reliability

Unlike generic Ethernet cables that fail under marine stress, this Furuno-specific solution is tested for 1000BASE-T speeds and CAT5e performance. It reduces downtime by preventing common issues like packet loss from poor shielding or connector corrosion. Anglers report clearer fish finder data over distance, while cruisers enjoy synchronized navigation across flybridge and salon displays.

Investing in quality cabling pays off in fewer repairs and consistent performance, keeping you focused on the water rather than troubleshooting electronics.
