    Description
    Ethernet Interface

    • 10/100BaseT(X) Ports (RJ45 connector)

      • 2 (1 IP, Ethernet cascade)
        Auto MDI/MDI-X connection

    • Magnetic Isolation Protection

      • 1.5 kV (built-in)

    • Optical Fiber

      • 100BaseFX
        Multi-Mode Single-Mode
        Fiber Cable Type OM1 50/125 µm G.652
        800 MHz x km
        Typical Distance 4 km 5 km 40 km
        Wavelength Typical (nm) 1300 1310
        TX Range (nm) 1260 to 1360 1280 to 1340
        RX Range (nm) 1100 to 1600 1100 to 1600
        Optical Power TX Range (dBm) -10 to -20 0 to -5
        RX Range (dBm) -3 to -32 -3 to -34
        Link Budget (dB) 12 29
        Dispersion Penalty (dB) 3 1
        Note: When connecting a single-mode fiber transceiver, we recommend using an attenuator to prevent damage caused by excessive optical power.
        Note: Compute the “typical distance” of a specific fiber transceiver as follows: Link budget (dB) > dispersion penalty (dB) + total link loss (dB).
