光纤收发器指示灯怎么看：速率与收发光信号

光纤收发器指示灯图解

光纤收发器指示灯：

 

上角——亮时代表1000M速率    

右上角——亮时代表100M速率    

左中间——亮时代表已接上尾纤，闪烁代表正在传输数据    

右中间——亮时代表已接上网线，闪烁代表正在传输数据    

左下角——亮时代表已接入电源线    

右下角——亮时代表全双工速率 ，灭时代表半双工

 

光纤接口类型：

FC 圆型带螺纹(配线架上用的最多)

ST 卡接式圆型

SC 卡接式方型(路由器交换机上用的最多)

PC 微球面研磨抛光

APC 呈8度角并做微球面研磨抛光

MT-RJ 方型,一头双纤收发一体( 华为8850上有用)

光纤模块:一般都支持热插拔,

GBIC Giga Bitrate Interface Converter, 使用的光纤接口多为SC或ST型

SFP 小型封装GBIC,使用的光纤为LC型（附件为一些跳线实物图）
