100BaseFX port
100Base-FX full-duplex SM or MM port, SC/ST 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.
The optical fiber connection supports the line to instruct enhance the reliability of network effectively
.
Suppose
: If you make your own cable, we suggest labeling the two sides of the same line with the same letter (A-to-A and B-to-B, shown as below, or
A1-to-A2 and B1-to-B2).
