Optimized DPMZM Based RoF Link Against Fiber Impairments

The demands of emerging wireless communication are higher bandwidth, low latency, high-quality multimedia applications, less environmental impact etc., with cost-effective network implementation. The Radio over Fiber (RoF) link will be the best substitute, and this paper presents an analytical and simulation of the dual parallel DE-MZMs based RoF link while considering of different optical fiber distances. The utility of dual parallel DE-MZMs in RoF link provides the significant enhancement in dynamic range of link in microwave photonic link. Further, it is found that the IM3 terms are approximate eliminated or 40.9 dB much lower w.r.t. fundamental signals for 1 km optical fiber length by the proposed DPMZM based RoF link. The analytical analysis is verified by simulation using OptSIM (Optical Simulator) software. Finally, the comparative analysis of the proposed DPMZM based RoF link with the conventional link confirms the optimization against third order intermodulation and fiber impairments. This optimization of the proposed link will be helpful for microwave photonic links without any digital processing.
