MDI/MDI-X auto connection makes switch easy to use for customers without considering the type of network cable.
100Base-FX Fiber port
100Base-FX full-duplex SM or MM port, SC/ST/FC type .The fiber port must be used in pair, TX (transmit) port connect remote
switch’s RX (receive) port; RX (receive) port connect remote switch’s TX (transmit) port.
