Performance enhancement of mapping multiplexing technique utilising dual-drive Mach–Zehnder modulator for metropolitan area networks PROJECT TITLE :Performance enhancement of mapping multiplexing technique utilising dual-drive Mach–Zehnder modulator for metropolitan area networksABSTRACT:A methodology to manage the eye gap distribution of mapping multiplexing technique (MMT) system is proposed and presented. The authors modelled and analysed a method to enhance the receiver sensitivity of MMT system by using optimised dual-drive Mach-Zehnder modulator. The proposed methodology offers larger eye gap for distorted Level-3 eyes. Based on the numerical calculation, the optimisation leads toward minimal eye closure. The performance of proposed system is shown to be improved by half-dozen.1 dB in terms of receiver sensitivity compared with the standard MMT system. Throughout the paper, the authors also discuss a numerical comparative analysis between the proposed MMT model, conventional MMT model, 33p.c come-to-zero on-off-keying (33%RZ-OOK), 50% RZ-OOK, sixty seven% carrier-suppressed RZ-OOK and four-ary amplitude shift keying in terms of positive chromatic dispersion tolerance and spectral potency.
