Physical Layout and Connection Points

The Fuji FNC360A-C20 weighs only 0.32 kilograms for flexible mounting. Its 120 mm width occupies minimal panel space. Two optical ports sit on the front panel clearly labeled. A snap‑in ZD connector secures each fiber cable firmly. Four LED indicators show system status at a glance. An internal 100 µF capacitor buffers short power interruptions.

Optical Transmission Characteristics

This system uses plastic optical fiber with a 1 mm core. The 660 nm red light provides visible signal confirmation. Therefore, technicians can see active links during troubleshooting. The maximum distance reaches 200 meters between stations. The data rate runs at 2.5 megabits per second. Consequently, the link supports most discrete and analog I/O updates.

Installation and Wiring Guidelines

Mount the Fuji FNC360A-C20 on a standard DIN rail. First, cut the plastic fiber to the required length. Then strip the outer jacket carefully without scratching the core. Insert the fiber into the ZD connector until it stops. Connect the transmit port of one unit to the receive port of the next. Repeat this process for all stations in the chain. Finally, apply power and verify the Link LED turns solid green.

System Topology and Application Notes

This optical link supports a daisy‑chain or loop topology. The maximum network includes up to 20 stations. Typical applications include large conveyor systems and paint booths. The link also suits high‑EMI areas like welding cells. For longer distances, add optical repeaters between segments. The system works with most Fuji PLCs and remote I/O racks.
