Furthermore, a comprehensive tutorial on high-performance, low-cost, and advanced optical transceiver (TRx) paradigms is presented. In this context, recent advances in high-performance digital signal processing algorithms and innovative optoelectronic components are extensively discussed. Moreover, based on the growing increase in the dynamic environment and the heterogeneous nature of different applications and services to be supported by the systems, we discuss the reconfigurable and sliceable TRxs that can be employed. The associated technical challenges of various system algorithms are reviewed, and we proffer viable solutions to address them.<\/jats:p>","DOI":"10.3390\/app11167554","type":"journal-article","created":{"date-parts":[[2021,8,17]],"date-time":"2021-08-17T21:27:40Z","timestamp":1629235660000},"page":"7554","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["A Review of Self-Coherent Optical Transceivers: Fundamental Issues, Recent Advances, and Research Directions"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5868-8045","authenticated-orcid":false,"given":"Isiaka","family":"Alimi","sequence":"first","affiliation":[{"name":"Instituto de Telecomunica\u00e7\u00f5es, Campus Universit\u00e1rio de Santiago, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6856-2216","authenticated-orcid":false,"given":"Romil","family":"Patel","sequence":"additional","affiliation":[{"name":"Department of Electronics, Telecommunications and Informatics, Instituto de Telecomunica\u00e7\u00f5es, Campus Universit\u00e1rio de Santiago, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6309-6818","authenticated-orcid":false,"given":"Nuno","family":"Silva","sequence":"additional","affiliation":[{"name":"Instituto de Telecomunica\u00e7\u00f5es, Campus Universit\u00e1rio de Santiago, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"given":"Chuanbowen","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronic Engineering, University of Melbourne, Melbourne, VIC 3010, Australia"}]},{"given":"Honglin","family":"Ji","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronic Engineering, University of Melbourne, Melbourne, VIC 3010, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1777-5403","authenticated-orcid":false,"given":"William","family":"Shieh","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronic Engineering, University of Melbourne, Melbourne, VIC 3010, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2101-5896","authenticated-orcid":false,"given":"Armando","family":"Pinto","sequence":"additional","affiliation":[{"name":"Department of Electronics, Telecommunications and Informatics, Instituto de Telecomunica\u00e7\u00f5es, Campus Universit\u00e1rio de Santiago, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4412-8025","authenticated-orcid":false,"given":"Nelson","family":"Muga","sequence":"additional","affiliation":[{"name":"Instituto de Telecomunica\u00e7\u00f5es, Campus Universit\u00e1rio de Santiago, University of Aveiro, 3810-193 Aveiro, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"708","DOI":"10.1109\/COMST.2017.2773462","article-title":"Toward an Efficient C-RAN Optical Fronthaul for the Future Networks: A Tutorial on Technologies, Requirements, Challenges, and Solutions","volume":"20","author":"Alimi","year":"2018","journal-title":"IEEE Commun.
