| 摘 要： | 光纤四波混频是导致ＯＦＤＭ系统的信噪比、接收灵敏度和误码率上升的主要非线性作用之一．本文从理论上分析了ＡＳＫ直接检测ＯＦＤＭ系统中四波混频对信噪比信道间串话及检测功率的恶化的影响，得出了在ＡＳＫ直接检测ＯＦＤＭ系统中四波混频光波功率和信号功率恶化系数随光纤参数和信号参数变化的关系，并以三信道ＯＦＤＭ为例作了数值分析．

| Abstract: | The Influence of fiber four-wave mixing on ASK direct detection OFDM is investigated.A theoretical study is presented for evaluating the effective four-wave mixing light power and power penalty when four-wave mixing light are overlapped on to a signal channel,the numerical analysis on three-channel demonstrates the dependence of FWM light power and power penalty on launched signal powers and fiber length. |
