Introduction

The IMC-21 industrial media converters are entry-level 10/100BaseT(X)-to-100BaseFX media converters designed to provide reliable and stable operation in harsh industrial environments. The converters are a cost-effective solution that run on either a 12 or 48 VDC power input and can operate reliably in temperatures ranging from -10 to 60°C. The rugged hardware design ensures that your Ethernet equipment can withstand demanding industrial conditions. The IMC-21 converters are easy to mount on a DIN rail or in distribution boxes.

  • 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

    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).
