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。
This paper introduces the overview of the 863 plan optoelectronic optoelectronic device Testbed and the latest experimental results. Four domestic DFB laser components as light source and three domestic erbium-doped fiber amplifiers were cascaded to amplify. The results showed that 282Km single-mode optical fiber with 4 channels of 622Mb / s channel and adjacent channel wavelength gap of 2nm was achieved at 1550nm band Regenerative relay transmission, the system error rate better than 1 × 10-12. Experiments show that with the successful development of China’s high-performance quantum well semiconductor laser and erbium-doped fiber amplifier, the next generation of optical fiber communication technology research, including the development of multi-level erbium-doped fiber amplifier amplification of high-speed high-capacity wavelength division multiplexing fiber There has been a solid foundation for the development and development of communication systems.
