Comnet FDX60M2M Small Size RS232/422/485 Fiber Transceiver
Overview
The FDX60M2M is an industrial-grade data transceiver that converts serial RS232, RS422, and 2-wire or 4-wire RS485 signals into fiber-optic transmission over multimode cable. Deploy this unit where you need to extend data links (panel-to-remote sensor, access control backbone, meter polling) beyond copper's noise-susceptible distance limits — typical surveillance backbone scenarios include connecting a central NVR to remote IP gateway units, or bridging isolated serial devices across long runs without EMI degradation. The unit handles DC–250 kbps bidirectional asynchronous or full-duplex RS data, drawing only 2 W at 9–30 VDC input.
Compatibility
FDX60M2M integrates with any surveillance or building-systems architecture using standard RS232, RS422, or RS485 control lines. Common pairings include Comnet IP gateway transceivers, remote Hikvision or Axis access-control readers requiring serial backhaul, legacy DVR or NVR serial ports, and industrial PLC networks requiring long-distance noise-immune links. Pair two units (one at each fiber end) to establish a full-duplex data bridge. Verify your receiving device supports the same baud rate and data format (simplex or full-duplex mode) before installation.
Installation Notes
Use ST optical connectors on multimode fiber (62.5 µm or 50 µm core). The transceiver supports two separate fiber strands for true full-duplex operation, or single-fiber variants for simplex links. Operating range depends on optical power budget: 16 dB (4 km max) or 23 dB (69 km max) — verify your fiber type and connector losses match the advertised budget. Mount in a 1U rack slot or wall-mount the compact 4.1 × 3.7 × 1.1 inch form factor. Maintain operating temperature from −40 °C to +75 °C and humidity up to 95% non-condensing. Comnet recommends the PS-A12060 power supply for industrial deployment. MTBF exceeds 100,000 hours. Comply with NEMA TS-1/TS-2 and Caltrans standards for critical traffic or utility backbone use.
