This trend will likely push the optoelectronics to their limits, thus requiring impairment compensation based on digital signal processing (DSP) techniques in the transceivers. In this paper, which is an invited follow-up of a tutorial given at ECOC 2023, we first present an overview of this evolving scenario and then propose a unified analytical model that is able to predict the performance of these new systems for both direct-detection and coherent transceiver types. We believe that this model can be useful for preliminary scalability studies of new access architectures (as it happens in international standardization bodies). Moreover, when they are deployed, it can be useful as a base for network planning tools, particularly if future transceivers will be, as expected, highly reconfigurable at the DSP level.<\/jats:p>","DOI":"10.1364\/jocn.516669","type":"journal-article","created":{"date-parts":[[2024,4,8]],"date-time":"2024-04-08T18:00:08Z","timestamp":1712599208000},"page":"C88","update-policy":"http:\/\/dx.doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Planning tools for next-generation DSP-based passive optical networks above 50G [Invited Tutorial]"],"prefix":"10.1364","volume":"16","author":[{"ORCID":"http:\/\/orcid.org\/0000-0003-0583-2626","authenticated-orcid":true,"given":"Giuseppe","family":"Rizzelli","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00bgk9508","id-type":"ROR","asserted-by":"publisher"}]}]},{"ORCID":"http:\/\/orcid.org\/0000-0003-1909-4281","authenticated-orcid":true,"given":"Roberto","family":"Gaudino","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00bgk9508","id-type":"ROR","asserted-by":"publisher"}]}]}],"member":"285","published-online":{"date-parts":[[2024,5,10]]},"reference":[{"key":"jocn-16-7-C88-R1","doi-asserted-by":"publisher","first-page":"31","DOI":"10.1109\/JLT.2019.2950889","volume":"38","author":"Wey","year":"2020","journal-title":"J.
