Digital predistortion for RSOAs as external modulators in radio over fiber systems

Optics Express, 2011
Reflective semiconductor optical amplifiers (RSOAs) can be used as external modulators in radio over fiber (RoF) links due to their amplification and modulation characteristics and colorless property. The nonlinear distortion of RSOA, however, limits its dynamic range. In this paper we demonstrate digital predistortion (DPD) linearization techniques to

基于RSOA再调制的RoF 与OFDM-PON混合系统仿真

Guangtongxin yanjiu, 2019
为弥补传统无线网络在射频链路难以到达的地方信号接收困难的问题,采用了将光载无线通信（RoF）技术作为一种无线接入方式与正交频分复用（OFDM）无源光网络（PON）有线接入网络相结合的方式,提出了一种基于外调制法单边带（SSB）调制方式承载60 GHz毫米波结合反射式半导体光放大器（RSOA）的有线与无线结合的双向传输系统,并完成了平台的搭建。在此基础上完成了理论分析和实验验证,通过仿真软件Optisystem,对基于RSOA的双向有线及无线混合接入系统背靠背以及光纤传输20 ...
