RJ45的8個(gè)接口定義?
RJ45接口信號定義,以及網(wǎng)線連接頭信號安排
以太網(wǎng) 10/100Base-T 接口:
Pin Name Description
1 TX+ Tranceive Data+ (發(fā)信號+)
2 TX- Tranceive Data- (發(fā)信號-)
3 RX+ Receive Data+ (收信號+)
4 n/c Not connected (空腳)
5 n/c Not connected (空腳)
6 RX- Receive Data- (收信號-)
7 n/c Not connected (空腳)
8 n/c Not connected (空腳)
以太網(wǎng) 100Base-T4 接口:
Pin Name Description
1 TX_D1+ Tranceive Data+
2 TX_D1- Tranceive Data-
3 RX_D2+ Receive Data+
4 BI_D3+ Bi-directional Data+
5 BI_D3- Bi-directional Data-
6 RX_D2- Receive Data-
7 BI_D4+ Bi-directional Data+
8 BI_D4- Bi-directional Data-
1 white/orange
2 orange/white
3 white/green
4 blue/white
5 white/blue
6 green/white
7 white/brown
8 brown/white
注:RJ45接口采用差分傳輸方式,tx+、tx-是一對雙絞線,擰在一起可以減少干擾。
