Ethernet Interface

  • 10/100BaseT(X) Ports (RJ45 connector): 8 Auto negotiation speed Full/Half duplex mode Auto MDI/MDI-X connection
  • Standards: IEEE 802.3 for 10BaseT IEEE 802.3u for 100BaseT(X) and 100BaseFX IEEE 802.3x for flow control
  • Optical Fiber: Note: When connecting a single-mode fiber transceiver, we recommend using an attenuator to prevent damage caused by excessive optical power.Note: Compute the “typical distance” of a specific fiber transceiver as follows: Link budget (dB) > dispersion penalty (dB) + total link loss (dB).
