| 摘 要： | 由于在ＷＤＭ＋ＥＤＦＡ光纤传输系统中使用常规单模光纤（ＳＭＦ）在１５５０ｎｍ窗口的大色散限制了传输距离，采用色散补偿光纤（ＤＣＦ）进行色散补偿是上前一种较为理想的方法。本文基于光纤ＷＤＭ＋ＥＤＦＡ＋ＤＣＦ的长距离传输系统，讨论了ＤＣＦ色散补偿对光纤非线性效应交叉相位调制和四波混频（ＦＷＭ）的影响，提出了采用ＤＣＦ集总、后置、非完全补偿的色散补偿方案，这种方案可合系统具有更佳的传输性能。

| Abstract: | Since dispersion of single mode fiber in the 1550nm wavelength region restricts optical signal to propagate a long haul link in WDM EDFA optical transmission systems,optimal method is to employ dispersion compensation fiber to compensate dispersion of single mode fiber in order to realize a long haul transmission.In this paper,we discussed the impact of DCF dispersion compensation on four wave mixing and cross phase modulation in WDM EDFA DCF systems.So,it is suggested that employing a lumped,under compensation,and postposition compensation scheme can improve the system transmission performance. |
