Using Fiber Media Converters with Copper Networks

The 21st century has seen a huge increase in using Ethernet for industrial automation applications such as remote monitoring. However, the advantages and versatility obtained from using Ethernet for industrial automation applications are offset by a number of drawbacks, one of which is signal interference. As a general rule, shop floor and substation environments are not nearly as friendly as what you would find in an air conditioned office, and for this reason, engineers are now using Fiber Ethernet to extend transmission distance and protect data from the effects of EMI (electromagnetic interference), or even Gigabit Ethernet to provide increased bandwidth. In addition, advanced redundancy solutions, such as STP/RSTP and Moxa’s own Turbo Ring protocol, provide the redundancy needed when implementing Ethernet with automation applications.

In this paper we cover the following topics:

  • Using Media Converters as Part of a Network
  • Going Beyond Media Conversion—LFP and FEF
  • Important Reminder: Use Media Converters in Pairs
  • What to Expect from Redundancy
