摘要

本文对50km外调制256-QAM DWDM光纤链路的相位稳定性进行了评价。分析光纤链路中的射频相位噪声是本研究的主要目的。研究了1550nm波长下前置放大器(EDFA)的射频相位噪声。误码率曲线、星座图和眼图是本文考虑的三个主要性能标准。

Effect of phase noise in Dense Wavelength Division Multiplexing (DWDM) networks

In this paper, the phase stability of 50 km externally modulated 256-QAM DWDM fiber optic link is evaluated. The analysis of RF phase noise in the fiber optic link is the main objective of this work. RF phase noise is mainly investigated with preamplifier (EDFA) configuration at 1550 nm wavelength. BER curves, constellation diagrams and Eye diagrams are the three main performance criteria considered through this paper.
