The transceiver is based on a vertical cavity surface emitting laser, which is used as the local oscillator for a heterodyne receiver and also feeds a phase-modulated reflective semiconductor optical amplifier (RSOA) transmitter. The modulation format used in the RSOA is a nonreturn-to-zero differential binary phase shift keying (DPSK) for the uplink, while the downlink is based on a Nyquist DPSK format. The central frequencies of the links are 2 GHz separated, and both links can be placed inside a 6.25-GHz frequency slot. The sensitivity of this transceiver is -43.5 dBm over a 50-km fiber. info:eu-repo/grantAgreement/ES/DGA/T25 info:eu-repo/grantAgreement/ES/MICINN/TEC2014-59583-C2-1-R info:eu-repo/grantAgreement/ES/MINECO/TEC2013-46917-C2-2-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.375 2016 ENGINEERING, ELECTRICAL & ELECTRONIC 95 / 259 = 0.367 2016 Q2 T2 PHYSICS, APPLIED 51 / 147 = 0.347 2016 Q2 T2 OPTICS 32 / 92 = 0.348 2016 Q2 T2 0.988 2016 Atomic and Molecular Physics, and Optics 2016 Q1 Electronic, Optical and Magnetic Materials 2016 Q1 Electrical and Electronic Engineering 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Izquierdo, David Universidad de Zaragoza (orcid)0000-0002-4746-3139 Lázaro, José Antonio Garcés Gregorio, Juan Ignacio Universidad de Zaragoza (orcid)0000-0003-3505-0078 5008 800 Universidad de Zaragoza Dpto.
