10/100/1000 Gigabit Fibre Converter – Extended Temperature

  • Connects 10/100/1000 Mbps copper to 1000 Mbps fibre
  • For use in extended temperatures
  • Cascading power on DIN rail installations
  • Dual USB power cable (optional)
  • Link Fault Pass-Through (LFPT) capability via a DIP Switch


Measuring less than 88.9mm (3.5 inches) deep and 50.8mm (2 inches) wide, and having both data connections on the same side of the unit—the IE-Giga- MiniMc-LFPT is the industry’s smallest media converter at a fraction of the cost of other alternatives. Link Fault Pass Through (LFPT) can be enabled/disabled via a DIP Switch on the unit, and is a useful diagnostic feature that assists the network administrator in indicating a fault condition on a given segment between the interfaces. With Plug-and-Play, Auto Negotiation and AutoCross operation, extreme operating temperatures (-25° to 85° C), DC or AC power, the IE-Giga- MiniMc-LFPT miniature media converter is easy and convenient to use. SFP port supports 100 Mbps or 1000 Mbps SFPs (fibre). This allows the customer to utilize the product for a Fast Ethernet circuit and later upgrade to Gigabit.
