1000BASE-X自协商是指1000BASE-X的链路(光纤或者屏蔽平衡铜线)双端互相广告其支持的能力,以达到链路双方工作的模式匹配。1000BASE-X自协商由IEEE Clause 37中定义,故又称为C37自协商。1000BASE-KX不使用C37自协商,而是使用C73自协商(后续DAC自协商部分会做详细探讨)。 1000BASE-X自协商允许链路段两端的设备广告自己的...
自协商状态机是理解1000BASE-X自协商机制的关键。这部分内容笔者以点带面基于几个常见的应用场景做一个简单的解析。如果读者想对细节理解得更为透彻,请自行阅读IEEE 802.3相关章节。 自协商状态机状态图 异常场景1 A端自协商使能,单端悬空,然后执行上电动作。 A端的状态机流程 进入状态“AN_ENABLE”; 进入状态“A...

1000BASE-X基于ANSI INCITS 230-1994(FC-PH)开发的物理层标准。1000BASE-X使用了与FC相同的8B/10B编码机制。

In 1000BASE-X and 1000BASE-KX functional modes, any /Dx.y/ following a /K28.5/ comma is replaced by the transmitter with either a /D5.6/ (/I1/ ordered set) or a /D16.2/ (/I2/ ordered set), depending on the current running disparity. The exception is when the data following th...
