This tutorial explores the evolution of technology used for optical interconnects and the trade-offs involved in designing low complexity, low power DSP and implementing direct detect and coherent, pluggable optical modules for data center applications. Design trade-offs include the selection of modulation format, baud rate, optical link design, forward error correction, signal shaping, and dispersion compensation.
In this tutorial, we discuss the evolution of the technology deployed for optical interconnects and the trade-offs in the design of low complexity, low power DSP and implementation for direct detect and coherent, pluggable optical modules for data center applications. The design trade-offs include the choice of modulation format, baud rate, optical link design, forward error correction, signal shaping and dispersion compensation.
