Entry-level industrial 10/100BaseT(X) to 100BaseFX media converters
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 to 48 VDC power input
Introduction
Specifications
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.

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).
