| 摘 要： | 光接收灵敏度与光发射信号的消光比大小和眼图的上升沿/下降沿陡度具有紧密相关性，试验研究表明，155Mbps光收发模块消光比在16-20dB之间时光接收灵敏度最佳，眼图的上升沿/下降沿陡度越陡越好，一般情况下随上升沿/下降沿陡度的变化光接收灵敏度具有2-3dB的差异。

| Abstract: | The optical receiver sensitivity is tight relativity with extinction-ratio of optical transmitting signal and ascending/descending gradient of eye-diagram.The experiment shows that the extinction-ratio of 155Mbps optical receiving-transmitting modules is between 16dB and 20dB,the optical receiver sensitivity keeps best.And the more sharp is the ascending/descending gradient of eye-diagram,the more is receiver sensitivity.In general,there are 2 to 3dB errors in optical receiver sensitivity with the change of ascending/descending gradient. |
