在本教程中,我们将讨论用于光互连的技术的发展,以及在设计低复杂性、低功耗DSP和实施数据中心应用的直接检测和相干可插拔光模块时的权衡。设计权衡包括调制格式、波特率、光链路设计、前向纠错、信号整形和色散补偿的选择。
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.
