摘要
掺铒光纤放大器(EDFA)和拉曼放大器(FRA)的使用,使得光纤通信系统中的入纤功率有了很大的提高。较高的入纤功率不仅会在光纤中引起各种非线性效应,对光脉冲的传输产生影响,也会对光纤本身的可靠性产生影响,为此介绍了高入纤功率对光纤系统的影响,分析了其产生的机理,并提出了应对措施。
The implement applications of erbium doped fiber amplifier （EDFA） and fiber Baman amplifier （FRA） make the launching power in optical fiber communications systems increased significantly. Many non-linear phenomena and their consequent effects on system performance are studied in detail. The possible harmful effects of high launching power on optical fiber communications systems are introduced. The fundamental principle of the effect of high input power in fiber is introduced. Then some corresponding countermeasure strategies are presented.
