The GE IFS D7600 EtherNav series (specifically the D7600-MM-X) is an industrial-grade Ethernet-to-Fiber media converter designed for high-reliability data transmission in harsh environments. This unit facilitates the conversion of 10/100 Mbps copper Ethernet signals into optical signals for transmission over multi-mode fiber optic cabling. By utilizing fiber, the D7600 series allows for massive distance extensions—far beyond the 100-meter limit of standard copper—while providing total immunity to electromagnetic interference (EMI) and lightning surges.

Key Application Fields
-
Intelligent Transportation Systems (ITS): Connecting roadside traffic controllers and sensors to a central network over long distances.
-
Security & Surveillance: Transmitting high-bandwidth IP camera data from remote perimeter fences to the main security office.
-
Industrial Automation: Linking PLCs and HMIs in factories where high-voltage machinery creates significant electrical noise.
-
Oil & Gas Facilities: Providing reliable data links across large refineries or pipelines where grounding issues often plague copper networks.
-
Campus Networks: Bridging separate buildings in a university or corporate campus using existing fiber infrastructure.
Product Usage Instructions
-
Mounting: Secure the unit in its operating environment. If used in a rack, slide the module into the IFS rack chassis. For field use, use the integrated mounting holes or a DIN-rail clip.
-
Copper Connection: Plug a standard Cat5e or Cat6 Ethernet cable into the RJ-45 port. The port is “Auto-MDI/MDI-X,” so you can use either straight-through or crossover cables.
-
Fiber Connection: Remove the dust caps from the ST/SC ports and connect your multi-mode fiber patch cables. Ensure “Transmit” (TX) on one unit connects to “Receive” (RX) on the other.
-
Power Up: Connect the 12–24V power source. Verify that the “Power” LED illuminates.
-
Status Verification: Check the “Link/Act” LEDs. A steady light indicates a successful physical connection, while flashing indicates active data traffic.
Q&A: Frequently Asked Questions
Q: What does the “-X” in the model name represent? A: The “X” is a placeholder for the connector type. Typically, “ST” denotes an ST-style bayonet connector, and “SC” denotes an SC-style snap-in connector.
Q: Can I use this multi-mode unit (MM) with single-mode fiber? A: No. Multi-mode electronics use different wavelengths and laser types. For single-mode fiber, you would need the D7600-SM version, which can transmit up to 20 km or more.
Q: Does this device require software configuration? A: No, the D7600 series is an unmanaged, “plug-and-play” device. It automatically detects speed and duplex settings without any user programming.
Q: What is the “Far End Fault” feature? A: This feature allows the unit to detect a break in the fiber optic cable and drop the copper link. This informs the connected switch or router that the path is down so that redundant network paths can be activated.
