MDI (straight-through cable):
MDI-X (Cross over cable):
100Base-FX fiber port
100Base-FX port works with full-duplex, SM or MM SC/ST. The fiber port may contain single fiber
bidirectional connectors, or dual fiber connectors. Dual fiber connectors must be used in pairs. The TX
(transmitting) port connects to the remote switch’s RX (receive) port; RX (receiving) port connects to the
remote switch’s TX (transmitting) port.
We advise to label the two sides of the cable with the same letter (A-to-A and B-to-B, shown as below, or A1-
to-A2 and B1-to-B2, etc.).
