Relative phase noise induced impairment in CO-OFDM optical communication system with distributed fiber Raman amplifier

Wu, Jiadi; Cheng, Jingchi; Tang, Ming; Deng, Lei; Songnian, Fu; Shum, Perry Ping; Liu, Deming (2014)

In this letter, we demonstrate that the interplay between Raman pump relative intensity noise and cross-phase modulation leads to a relative phase noise (RPN) that brings non-negligible performance degradation to coherent ...

Relative phase noise estimation and mitigation in Raman amplified coherent optical communication system

Cheng, Jingchi; Tang, Ming; Fu, Songnian; Shum, Perry Ping; Liu, Deming; Xiang, Meng; Feng, Zhenhua; Yu, Dawei (2014)

The interplay between the stochastic intensity fluctuation of Raman pump laser and cross-phase modulation (XPM) effect in transmission optical fiber leads to additional phase noise, namely, relative phase noise (RPN) of ...
