基于DSP技术实现光纤LAN系统Q值在线检测

The Implementation of Q Factor On-line Detection Based on DSP Technology in Optical Fiber LANs

针对光纤局域网 ( L AN)中物理层的特点 ,提出了一种基于数字信号器 ( DSP)技术的系统 Q值在线检测方法 ,讨论了其数理模型并进行了一系列模拟测试 .结果表明 ,该方法准确可行。

In view of the characteristics of PHY(physical layer) in optical LAN(local area network), an on line method for Q factor detection based on DSP(digital signal processor) technology is put forward and its mathematical physical model is discussed. A series of simulative tests indicate that the method is valid, feasible, and convenient.
