目前标准有两种：586a和586b
标准568A：绿白-1，绿-2，橙白-3，蓝-4，蓝白-5，橙-6，棕白-7，棕-8 标准568B：橙白-1，橙-2，绿白-3，蓝-4，蓝白-5，绿-6，棕白-7，棕-8 【👈用这个】
布在墙里的网线应该使用586b（应该是568B），现在几乎所有网络设备都支持自适应，所以几乎全部连接线都采用568B的标准。

压接网线水晶头的步骤与技术分析
一、所需工具与材料
在开始压接网络线水晶头之前，需要准备以下工具和材料：
网线（Cat5e, Cat6 或者更高级别的）RJ45 水晶头切割/剥皮工具网线测试仪器压线钳
二、步骤说明
2.1、裁剪网线
首先，使用切割工具按照所需长度裁剪网线。
**注意：**预留足够的长度以便操作，并考虑到可能出现的误差。
2.2、剥离外壳
使用剥皮工具小心地剥离网线的外层塑料壳，露出内部的8根颜色各异的线。
**警告：**不要剥得过深，以免切断内部的铜线。
2.3、排列线序
按照规定的线序排列这8根线。在大多数情况下，采用的是T568B线序，即从左到右依次为：橙白、橙、绿白、蓝、蓝白、绿、棕白、棕。
**提示：**严格遵守线序规则，否则会导致网络连接失败。
2.4、切平线头
排列好线序后，再次使用切割工具，将线头切齐。
**提示：**保持线头整齐能够确保更好地插入RJ45水晶头。
2.5、插入水晶头
将线头插入RJ45水晶头，确保每根线都已经触及水晶头的顶部。
2.6、压接水晶头
将带有水晶头的网线插入压线钳，然后用力压紧，使水晶头牢固地连接在网线上。
2.7、测试连通性
最后，使用网络测试器检查每根线是否连通。
三、错误排查
如果测试结果显示网络线未能正常连通，那么可能存在以下问题：
线序排列错误水晶头没有完全压实网线被剥皮工具割断
在此情况下，应重新进行压接操作。
