| 摘 要： | 报道了一个使用光纤放大器的两路非相干频分复用光纤传输实验系统。系统采用国产ＤＦＢ激光器作光源，用意大利生产的光纤放大器作在线放大器，用自制的光学谐振腔作光学滤波器和解复用器，采用ＦＳＫ调制制式，将１４０Ｍｂ／ｓ非归零伪随机码传输了５０公里，得到了很好的眼图。在频道间距为１０ＧＨｚ情况下，未观测到邻道干扰和光纤放大器的非线性现象。

| Abstract: | An experimental two-channel noncoherent FDM optical fiber transmission system with an in-lineEDFA is reported. The home-made DFB LDs are used as sources.The EDFA is made by Pirelli Inc.,Italy. The optical filter made in our laboratory is used as a multiplexer /filter. The FSK modulation formatis utilized. Good eye diagrams are obtained under the condition of the frequency spacing being 10GHz, andcrosstalk and nonlinearity of the EDFA are not observed. |
