Impact of Subcarrier-Routing Devices on the Performance of DSCM Coherent Systems Evaluated with Analytical Models

Paper in proceeding, 2025

This paper focuses on the application of an analytical model for faster and reliable transmission characterizations of novel optical networks employing Digital Subcarrier Multiplexing transceivers. This transmission model is thought to be applied in metro-access networks, for which it is first demonstrated for single links. In this work, the model is applied to analyze the system-level performance of a link, including, as a device under test, a 2-Ring Assisted Mach-Zehnder Interferometer (RAMZI) interlacer filter used to perform optical routing at the subcarrier level, and to quickly identify the impact of theparameters of the device in the overall transmission.
