| 摘 要： | 报道了2．5Gb／s光数字信号的异步取样实验，并通过软同步算法，得到了待测光数字信号眼图、Q值和误码率（BER），实验结果与采用高速示波器测量的结果较为一致。通过异步取样结合数据的软同步算法，具有实现更高速率光数字信号在线监测的潜力。

| Abstract: | An experiment about asynchronous sampling was reported to monitor the 2.5 Gb/ s optical signal performance. Eye diagram, Q factor and BER were acquired by analyzing and calculating the sampling result. Compared with the eye diagram observed by oscilloscope, the experimental results matched perfectly. This report shows that the asynchronous sampling,with data analyzing and calculating, can monitor the optical signal performance well,it does not need lock recovery,and it is independent of data ratio and pattern. |
