MDI-X (Cross over cable)
MDI/MDI-X auto connection makes IT-ES3020-IU-4GS series 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 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).
1000SFP fiber port (mini-GBIC)
1000BaseSFP fiber port adopts gigabit mini-GBIC transmission, can choice different SFP module according to different transfer distance.
Fiber interface must use for pair, TX port is transmit side, must connect to RX (receive side). The fiber interface support loss line indicator.
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).
