Abstract :
A methodology to control the eye opening distribution of Mapping Multiplexing Technique (MMT) system is proposed and presented. We modeled and analyzed a method to enhance the receiver sensitivity of MMT system by using optimized Dual-Drive Mach-Zehnder Modulator (DD-MZM). The proposed method offers larger eye opening for distorted higher-level eyes. Based on the numerical calculation, the optimization leads towards minimal eye closure in comparison to conventional MMT system. In comparison to the conventional MMT system, the optimization leads in to the 6.1 dB improvement in terms of receiver sensitivity.
