反向抽运掺铒光纤放大器的基本特性 摘 要 掺铒光纤放大器(EDFA)是光纤通信系统中的关键器件，掺铒光纤放大器(EDFA)的研制成功以及波分复用技术的广泛应用，极大地增加了光纤通信传输的信息容量并延长了光纤通信的传输距离，光纤通信得到了快速的发展。如何利用现有的光纤传输网络来满足日益膨胀的容量需求，已成为光纤通信领域研究的重要课题。因此，提升光纤通信容量的研究开始转移到新型的、更加高效的掺铒光纤放大器上。反向抽运掺铒光纤放大器输出信号功率比同向掺铒光纤放大器输出功率更高。因此对反向抽运掺铒光纤放大器的基本特性研究将有助于反向抽运掺铒光纤放大器在光纤通信中更广阔的应用使光纤通信的整体水平上一个新的台阶。 关键词： 光纤通信； 反向掺铒光纤放大器 ； 基本特性 Reverse pumping erbium doped fiber amplifier basic characteristics Abstract Erbium-Doped Fiber Amplifier (EDFA) plays an important role in the optical fiber communication system, mixed bait the successful development of the fiber amplifier and WDM technology application, enormously increased optical communications transmission of information capacity and extend the optical fiber transmission distance, Optical fiber communication obtained fast development. How to use the existing optical fiber transmission network to meet soaring capacity demand has become an important field of optical fiber communication topic. So ascension optical fiber communication capacity study began transferred to the new, more efficient mixing fiber amplifier bait. Reverse pumping erbium doped fiber amplifier output signal power than the coincidental erbium doped fiber amplifier output power. So to reverse pumping erbium doped fiber amplifier the basic characteristic of the research will help reverse pumping erbium doped fiber amplifier in fiber communications wider application make optical communications overall level go up to a new stage.
