【摘要】 介绍了８６３计划光电子主题光电子器件试验床（Ｔｅｓｔｂｅｄ）的概况及其最新的实验结果。采用４只国产ＤＦＢ激光器组件为光源、３台国内研制的掺铒光纤放大器作级联放大，实现了在１５５０ｎｍ波段、４路６２２Ｍｂ／ｓ信道、相邻信道波长间隙为２ｎｍ的２８２Ｋｍ单模光纤无再生中继传输，系统误码率优于１×１０－１２。实验表明，随着我国高性能的量子阱半导体激光器和掺铒光纤放大器的研制成功，进行下一代光纤通信技术的研究，包括开展具有多级掺铒光纤放大器放大的高速大容量波分复用光纤通信系统的研制和开发已有了坚实的基础。更多还原

【Abstract】 An OFC testbed for optoelectronic devices is reported in this paper. It aims to provide a systemapplication environment for the evaluation and optimization of newly - developed optoelectronic devices.The 4 × 622Mb/ s HD- WDM nonsenerated optical fiber transmission experiment over 282Km ofconventional fiber has been successfully demonstrated with BER better than 1 × 10-12 by using domesticMQW DFB LDs and 3 cascaded EDFAs. Some issues on gain equalization, crosstalk, power penalty, etc.,are discussed based on the experimental results.更多还原
