In addition, the gridless nature of filterless networks make that some (un)intentional effects such as transponders laser drift might disrupt the proper operation of lightpaths. To overcome these issues, we present a monitoring system exploiting data analytics and cost-effective optical spectrum analyzers to achieve smart filterless network operation. Experimental measurements are used to validate the proposed data analytics-based approaches, as well as to find the optimal resolution to achieve maximum performance with minimum cost.This work was partially supported by the EC through the METRO-HAUL project (G.A. nº 761727), from the AEI/FEDER TWINS project (TEC2017-90097-R), and from the Catalan ICREA Institution.Peer ReviewedPostprint (author's final draft
