A new flexible ONU design for UDWDM-PON with coherent transceivers and smart activation process
(2014)
Text en actes de congrés
Accés restringit per política de l'editorialWe present a novel ONU architecture for coherent UDWDM-PON with randomly distributed ONU wavelengths. The ONU is built with one or two lasers exhibiting simple limited thermal tunability in a specific optical band, where ... -
Demonstration of continuous multiple access with image-rejection coherent receiver and DML transmitters
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Text en actes de congrés
Accés restringit per política de l'editorialWe demonstrate a UD-WDM PON using DML transmitters with multilevel intensity modulation, both in base-band and RF, and a spectrally-efficient heterodyne receiver. We provide comparison with a homodyne receiver. Two users ... -
Half-duplex transmission avoiding rayleigh backscattering crosstalk in UDWDM-PON with coherent receivers
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Text en actes de congrés
Accés obertUltra Dense Wavelength Division Multiplexing (UDWDM) is a promising technique for access PON, introducing the wavelength-to-the-user concept. The key enabling technology will be a new cost-effective coherent detection ... -

Simple intradyne PSK system for UDWDM-PON
(2012-12-17)
Article
Accés obertA homodyne coherent receiver for ultra-dense WDM-PON with off the shelf components is presented. It consists of a conventional DFB, phase switched clock signal, an optical coupler instead of a 90º hybrid, balanced ...
