Abstract: Duobinary signal is a three level signal which has higher dispersion tolerance and better bandwidth efficiency than conventional binary signal formats. Optical duobinary signal can be generated by using either a dual arm Mach Zehnder Modulator (dual arm MZM) or a single arm Mach Zehnder Modulator (single arm MZM). This paper deals with the simulation and performance comparison of duobinary transmission systems with dual arm MZM and single arm MZM using OptSim software.

Keywords: duobinary, dual arm Mach Zehnder Modulator dual arm MZM, single arm Mach Zender Modulator single arm MZM
