Abstract

This paper has demonstrated the hybrid pumped laser sources based hybrid traveling wave SOA and optical EDFA amplifies for the signal quality improvement. The previous effective noise figure and fiber loss variations are clarified against wavelength band with/without amplification. The related previous signal output power versus Raman/EDFA pumped amplification and signal power conversion efficiency are indicated versus the launched pump power with the Raman/EDFA pumped amplification. The signal quality factor/BER against the transmission distance with/without amplification after receiver side. The modified amplified light signal power is demonstrated after 300 km distance SMF channel with wavelength band variations. The modified amplified light signal power is clarified after 300 km distance SMF channel by using optical power meter. The modified amplified light signal power is clarified after 300 km distance SMF channel with time band variations. The modified amplified electrical signal power is demonstrated after 350 km distance SMF channel with frequency band variations. The modified amplified electrical signal power is clarified after 350 km distance SMF channel with time band variations. The modified amplified electrical signal power is demonstrated after 350 km distance SMF channel by using electrical power meter.

基于混合行波 SOA 和光学 EDFA 放大器的混合泵浦激光源，用于改善信号质量

本文展示了基于混合行波 SOA 和光 EDFA 放大器的混合泵浦激光源，以提高信号质量。阐明了之前的有效噪声系数和光纤损耗在有/无放大情况下与波长带的变化关系。相关的先前信号输出功率与拉曼/EDFA 泵浦放大的关系，以及信号功率转换效率与拉曼/EDFA 泵浦放大的发射泵浦功率的关系均已说明。信号质量因子/误码率与接收端经过/未经过放大的传输距离的关系。在波长带变化的 300 千米距离 SMF 信道上，展示了经改进的放大光信号功率。通过使用光功率计，明确了 300 千米距离 SMF 信道后的修正放大光信号功率。经过 300 千米距离 SMF 信道的时间波段变化后，经修正的放大光信号功率得以明确。经过 350 千米距离的 SMF 信道后，经过修改的放大电信号功率在频带上发生了变化。经过时带变化的 350 千米距离 SMF 信道后，经过改进的放大电信号功率得到了明确。使用电功率计展示 350 千米距离 SMF 信道后的修正放大电信号功率。
