1756-IF8H

開始以太網(wǎng)只有10Mbps的吞吐量，使用的是帶有沖突檢測的載波偵聽多路訪問（CSMA/CD，Carrier Sense Multiple Access/Collision Detection）的訪問控制方法。這種早期的10Mbps以太網(wǎng)稱之為標準以太網(wǎng)，以太網(wǎng)可以使用粗同軸電纜、細同軸電纜、非屏蔽雙絞線、屏蔽雙絞線和光纖等多種傳輸介質(zhì)進行連接。并且在IEEE 802.3標準中，為不同的傳輸介質(zhì)制定了不同的物理層標準，在這些標準中前面的數(shù)字表示傳輸速度，單位是“Mbps”，zui后的一個數(shù)字表示單段網(wǎng)線長度（基準單位是100m），Base表示“基帶”的意思，Broad代表“寬帶”。
