摘要 对于给定的非线性损伤,对喇曼/掺Er混合光纤放大器(HFA)结构进行优化,即优化光纤喇曼放大器(FRA)与掺Er光纤放大器(EDFA)的增益比和色散补偿光纤(DCF)长度比,得到一种最优HFA结构。分别比较了最优HFA、一般HFA、全FRA和全EDFA用作接收机前置放大器的噪声性能,以及用于多级链路在线放大器时系统所能到达的最大可传输距离。结果表明,最优HFA能提高系统性能。 By optimizing the gain ratio and dispersion compensation fiber length ratio of Raman/erbium-doped hybrid fiber amplifier(HFA),a novel optimal HFA configuration was presented for given non-linearity impact.The noise performances of optimal HFA,other HFA,all erbium-doped fiber amplifiers(EDFA) and all fiber Raman amplifiers(FRA) are compared for the use as preamplifiers.The maximum reachable distances of multi-span systems were analyzed when these fiber amplifiers are used as inline amplifiers.The optimal HFA can improve the amplifying system performance.
