交换机的传输模式有全双工，半双工，全双工/半双工自适应
交换机的全双工是指交换机在发送数据的同时也能够接收数据，两者同步进行，这好像我们平时打电话一样，说话的同时也能够听到对方的声音。交换机都支持全双工
它可以为接入交换机的任意两个网络节点提供独享的电信号通路。最常见的交换机是以太网交换机。其他常见的还有电话语音交换机、光纤交换机等。SIEMENS: 3RK 3RA 3RB 3RF 3RG 3RH 3RN 3RP 3RS 3RT 3RV 3RX 3SK 3TC 3TD 3TG 3TH 3TK 3TS 3TX 3UF 3UG 3LD 8WD 6GK 6SE70 6SY 6DD 6RY 6SB 6SL39特价供应
