摘要

本文提出了一种同时工作于c波段和l波段的混合光放大器的设计方法。我们的配置使用掺铒光纤放大器(EDFA)作为助推器来获得c波段的光增益，使用分布式拉曼放大器(DRA)提供l波段的增益并控制增益纹波。放大器的性能根据开关增益和纹波、光信噪比(OSNR)和噪声系数(NF)进行计算。我们的结果显示，在65nm带宽上，开关增益为17db，纹波高达2db。在120 km处，OSNR大于35 dB, NF小于4 dB。从90公里到180公里的光纤链路进行了分析。

Design of a wideband hybrid EDFA with a Fiber Raman Amplifier

This paper presents a new design methodology for hybrid optical amplifiers operating simultaneously at C-and L-bands. Our configuration uses an Erbium Doped Fiber Amplifier (EDFA) operating as a booster to obtain optical gain over the C-band and a Distributed Raman Amplifier (DRA) to provide gain over the L-band and control the gain ripple. The amplifier performance was computed in terms of on-off gain and ripple, Optical Signal to Noise Ratio (OSNR), and Noise Figure (NF). Our results show on-off gain from 17 dB with ripple up to 2 dB over a 65 nm bandwidth. The OSNR was higher than 35 dB with NF lower than 4 dB at 120 km. Fiber links from 90 km up to 180 km have been analyzed.
