Connector and Connection Media Description

7.1
1000BASE-T/100BASE-TX/10BASE-T port

The 1000BASE-T/100BASE-TX/10BASE-T port is adaptive to three rates, and supports automatic MDI/MDIX
Crossover functions at the three rates.
1000BASE-T complies with the IEEE 802.3ab standard, the connected cable is 100-ohm CAT5 or CAT 5e
unshielded twisted pair UTP or shielded twisted pair STP. The maximum distance supported is 100 meters.
The 1000BASE-T port uses 4 pairs of wires for data transmission, and all 4 pairs of wires need to be
connected. The connection of the twisted pair used by the 1000BASE-T port is shown in the following

In addition to the above cables, the 100BASE-TX/10BASE-T port can use 100-ohm CAT3/4/5 cables for 10
Mbps transmission and 100-ohm CAT5 cables for 100 Mbps transmission. All of them can support a
maximum of 100 m distance. The following are the definitions of the pinouts of 100BASE-TX/10BASE-T:
