Encompassing Filtering Effects in Transceiver Models for Converged Metro-Access Networks

We present a comprehensive experimental analysis of filtering penalties in metro-access scenarios, characterized by cascades of ROADMs and optical amplifiers. This analysis evaluates the impact of various configurations, considering filter bandwidths, data rates, and received optical power. The novelty of this work lies in the derivation and validation of a transceiver model that encompasses filtering penalties, along with the application of this model to facilitate end-to-end lightpath deployment in converged network-as-a-service environments for fog computing, aiming to enhance spectral efficiency.
