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...
未编码的8bit信息分别用A、B、C、D、E、F、G、H(H为MSB,A为LSB)表示,已编码的10bit信息分别用a、b、c、d、e、i、f、g、h、j表示。使用以下约定为每个有效代码组Code-group指定了一个名称:/Dx.y/用于256个有效数据data code-groups,/Kx.y/适用于特殊控制代码组special code-groups,其中x是位EDCBA的...

用户可以简单记忆下多模光纤的特性(OM的数字越大光纤越贵,性能越好)。SMF为单模光纤,以太网领域一般用常规的B1.1,B1.3。 光模块发送器特性 LX的光模块可以是单模,也可以是多模。网管员在器件选型的时候需要注意鉴别(实际使用时光纤的模式和光模块的模式需相同)。 光模块接收器特性 SX-PMD 典型传输距离 光模块发送...

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...
