摘　　要：以Photonic Transmission Design Suite仿真试验平台为基础对EDFA和RFA的特性进行了较详细的研究设计了一个3 dB带宽为4.25 THz光信噪比在193.1 THz附近达38.5 dB增益起伏小于1 dB的带宽为3.75 THz的混合光放大器并将其应用于一个4信道的DWDM系统中经传输230 km后每路信号的输出光信噪比达到33.14 dB输出光功率达到4 W误码率达到3.The paper studies the characteristics of EDFA and RFA in detail on the base of emulation experiments using PTDS, which is a simulation platform for optical transmission system emulation. A 1dB-gain-flatness-bandwidth reaching 3.75 THz, 3dB-bandwidth reaching 4.25 THz and OSNR at 193.1 THz reaching 38.5 dB hybrid amplifier comprised of a distributed Raman amplifier and an EDFA has been achieved and is applied in a 4-channel DWDM communications system. After 230 km transmission, the output signals are excellent. The output OSNR reaches 33.14 dB, the output power reaches 4 mW and the BER reaches 3.810-10.
