  • PAM4 Optical Module Principle

    PAM4 Optical Module Principle

    PAM4 is an optical modulation technique that allows for higher data rates and increased spectral efficiency compared to NRZ. In PAM4, each symbol represents multiple bits of information by varying the amplitude of the optical pulse to four distinct levels. Figure 1-1 shows the typical waveform. PAM4 is a four-level pulse amplitude-modulated signal, which can be electrical or optical. Traditionally, digital signals are encoded for transmission in two levels, 0 and 1. Previous generations of serial data standards used non-return-to-zero (NRZ) encoding, rendering bits distinct high- and. Traditionally, in photonic PAM-4 transmitters, an MZM is driven by an electrical digital-to-analog converter (DAC) with an electrical driver, which requires energy-inefficient electronics. Implementations with nested modulators and drivers also exist, but they typically have larger footprints. In this example, you will learn how to: The system in this example contains the following elements: This page contains 2 sections. The simulation can be set up from a new simulation, starting at.
