Limit beat-frequency noise by employing receive low-pass filter and earn extra power budget margin for dual-band RSOA-based WDM-PON

Abstract

In this work, we use a low-pass filter in the burst-mode receiver between PIN+TIA and LA to optimize the receive bandwidth, and finally to improve the receiver performance of uncooled Reflective-SOA-based WDM-PON significantly. In addition, an extra power budget is earned for further development.
