Unmanaged 4 Port Industrial 10/100 Ethernet-Fiber 100BaseFX Converter

Contained in a plastic case that secures data transmission by using fiber optic transmission to provide immunity from EMI/RFI interference. Ethernet is used for transmitting a signal up to 2 Km(6,600 ft), and is the perfect solution for applications where transmission must be protected from electrical exposure, surges, lightning or chemical corrosion.

The NS-205FC operates at either half or full duplex mode. In full duplex mode, range is 2km with 62.5/ 125µm fiber cables; in half duplex mode, range is 412m with 62.5/ 125µm fiber cables.

The Ethernet supports 10/ 100M auto-negotiation feature and auto MDI /MDIX function
  • Automatic MDI / MDI-X crossover for plug-and-play
  • Each port supports both 10/100 Mbps speed auto negotiation
  • Store-and-forward architecture
  • Full duplex IEEE 802.3x and half duplex backpressure flow control
  • 3.2Gbps high performance memory bandwidth
