Physical Impairment Modelling in Flexible Optical Node Architectures
Description

One major goal in this project is to develop an analytical formulation,as well as a stochastic Monte-Carlo (MC) simulator, that allow us to study in a rigorous way the impact of in-band crosstalk, both incoherent and coherent, originated in CDC ROADMs in the performance of flexible grid networks, considering 16-QAM and 64-QAM 400 Gbps signals.

On a network-side perspective, the emergence of modulation formats with higher-order constellations and, consequently, with stricter performance margins has
increased the importance of physical impairment awareness in the network planning process. Thus, it is essential to incorporate the effects of in-band
crosstalk, along with other effects, in an impairment-aware routing and spectrum assignment (RSA) framework. This framework should be able to efficiently
provision paths and spectrum for superchannels based on M-QAM carriers in a CDC-ROADM network, while using the physical model as a performance validation
tool for candidate optical paths
