Paper Abstract

Fluctuations of optical and electronic noise, as well as other non-linear phenomena, affects the performance of optical channels in fiber-optic communication networks. Estimating and tracking channel performance at the receiver in real-time is a critical function to the integrity of communications service. This is realized when the receiver is equipped with mechanisms that perform in-service, in-real time and at low cost. In addition, another mechanism must be employed that reassigns non-performing channels to others for uninterrupted service. In this paper, we evaluate the noise and performance degrading mechanisms in optical links; we describe a method for in-service performance estimation, and performance tracking. In addition, we adopt a supercontinuum source to cost-efficiently generate a comb of twenty optical channels and we simulate it. Finally, we develop a protocol for remedial actions such as multiple-channel equalization and proactive single or multiple switch-to-protection channel.
