由于声光滤波器在密集波分复用系统中具有不可比拟的应用潜力，它在光通信研究中的地位日益重要。与Fabry-Perot相比，AOF具有更大的调谐范围与带通比，速度快上千倍，无迟滞（全光纤法布里-珀罗的问题），能够并行处理许多波长通道的时间（Fabry-Perot是一种单态器件，除非以复杂且固有损耗的方式进行组合），并且能够配置为4端口交换机
The acousto-optic filter (AOF) is becoming increasingly important in optical communication research because of its unmatched potential in densely-packed WDM systems. In comparison to the Fabry-Perot, their main competitor, AOFs have a larger tuning range-to-bandpass /ratio, are more than a thousand times faster, are free of hysteresis (a problem with all-fiber Fabry-Perots), are able to parallel process many wavelength channels at a time (the Fabry-Perot is a single-state device, unless ganged in a complicated and inherently lossy way) and are able to be configured as a 4-port switch
