A Review of Physical Layer Impairments in DWDM Networks: Detection and Mitigation Methods
摘要
In a DWDM optical network, it is essential for the design engineer to estimate the penalties that may impact the optical circuits in their design, possess a comprehensive understanding of the underlying causes of these penalties, and consider strategies to mitigate or minimize them to enhance network efficiency and maximize capacity. We will discuss pertinent studies that investigate and evaluate these concerns via various approaches, while emphasizing research that used alternative solutions to alleviate these consequences for the last decade.
