This chapter provides an analysis of an external intensity modulation direct‐detection (IMDD) link employing a Mach‐Zehnder modulator (MZM). It provides a largely qualitative description of these links with the intention to provide some intuition into their operation. The analysis focuses on a mathematical description of the relevant link performance metrics, and supporting experimental data are shown. Equations are presented in linear and decibel form, where the latter facilitates compact equations for link design and analysis. The chapter reviews schemes to linearize the modulation transfer function. Finally, it concludes with an analysis of propagation effects that builds on the material. The three core components to the IMDD links under consideration are a laser, a MZM, and a photodetector. The shot noise limit is an important operation condition for an IMDD link employing an external MZM.
