While the proposed combination increases the data-rate and the number of users through the inclusion of NOMA and multiCAP, the coherent reception increases the range and splitting factor of the network through optical power budget enhancement. The proposed system is experimentally evaluated providing a 20 Gb/s aggregated data-rate per wavelength with 10G optoelectronics and applied in two main PON scenarios with four spectral configurations from full-band CAP to four-band multiCAP. The first PON scenario consists of an existing PON that the network operator requires to increase the number of users; NOMA with full-band CAP or multiCAP can be introduced replacing one or more users of the existing PON by one or several new sub-networks and multiplexing the sub-networks by NOMA. In the other PON scenario, several PONs can be nested sharing an initial splitter and achieving a larger number of users by the combination of NOMA and multiCAP. The proposed techniques are fully compatible with other multiplexing techniques such as dense wavelength division multiplexing, which should be considered to achieve higher numbers of users. info:eu-repo/grantAgreement/ES/DGA/T20-20R info:eu-repo/grantAgreement/EC/H2020/876967/EU/Big data pRocessing and Artificial Intelligence at the Network Edge/BRAINE This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 876967-BRAINE info:eu-repo/grantAgreement/ES/MINECO-FEDER/ALLIANCE-TEC2017-90034-C2-2-R info:eu-repo/grantAgreement/ES/MINECO-FEDER/FOANT-TEC2017-85752-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 4.508 2021 OPTICS 22 / 100 = 0.22 2021 Q1 T1 COMPUTER SCIENCE, HARDWARE & ARCHITECTURE 12 / 54 = 0.222 2021 Q1 T1 TELECOMMUNICATIONS 29 / 92 = 0.315 2021 Q2 T1 COMPUTER SCIENCE, INFORMATION SYSTEMS 55 / 163 = 0.337 2021 Q2 T2 1.376 2021 Computer Networks and Communications 2021 Q1 11.8 2021 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Altabas, Jose A.
