Entry-level industrial 10/100BaseT(X) to 100BaseFX media converter

Note: The Green Core Product Identity of the IMC series will be phased in starting July 1, 2014. During the product transition period, you may still receive products that use the previous panel design. Please click here to learn more about Moxa’s Green Core product transition.

Features and Benefits 

  • Multi-mode or single-mode, with SC or ST fibre connector
  • Link Fault Pass-Through (LFP)
  • DIP switches to select FDX/HDX/10/100/Auto/Force


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 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..
