5 port 10/100 switch with 2x Fiber ports (FX)

There are two 100M Fiber Ports and three 10/100M UTP Ports. It is applicable to use in small patterns of Optical Fiber Ethernet as Fiber Repeaters or Ethernet single / multimode fiber converters, and other special requirements of the environment.


  • Optical-Electric Ethernet signals between 10/100M UTP ports (TX) and 100M optical fiber interfaces (FX).
  • Support 3x 10/100M UTP + 2x 10/100 FX (Singlemode or Multimode)
  • UTP port supports MDI / MDI-X auto crossover
  • Broadcast storm protection
  • Supporting max 1916 bytes frame
