Quaternary TDM-PAM and its implications for TDMA equipment
Dris, Stefanos; Bauwelinck, Johan; Yin, Xin; Schrenk, Bernhard; Lázaro Villa, José Antonio; Katopodis, Vasilis; Bakopoulos, Paraskevas; Verbrugghe, Jochen; Avramopoulos, Hércules (2012)
Text en actes de congrés
Accés restringit per política de l'editorialThe migration towards a 20 Gb/s quaternary TDM-PAM passive optical network with chirped and non-linear optical transmitters is experimentally studied. We show that a loss budget of 27.3 dB is compatible together with a ... -
Quaternary TDM-PAM as upgrade path of access PON beyond 10Gb/s
Verbrugghe, Jochen; Schrenk, Bernhard; Bauwelinck, Johan; Yin, Xin; Dris, Stefanos; Lázaro Villa, José Antonio; Katopodis, Vasilis; Bakopoulos, Paraskevas; Avramopoulos, Hércules (2012-12-10)
Article
Accés obertA 20 Gb/s quaternary TDM-PAM passive optical network with chirped and non-linear optical transmitters is experimentally demonstrated. The migration from legacy TDM-PONs and the implications of using available 10 Gb/s ... -
SOA/REAM as Vector Modulator for QAM Upstream
Schrenk, Bernhard; Fàbrega Sánchez, Josep Maria; Kazmierski, Christophe; Lázaro Villa, José Antonio; Prat Gomà, Josep Joan (2011)
Text en actes de congrés
Accés restringit per política de l'editorialSimultaneous encoding of information in the optical phase and amplitude for upstream transmission is demonstrated with an integrated SOA/REAM of small form factor. The crosstalk penalties between the QAM tributaries are ... -
Test-bed functionality of the SARDANA hybrid NG-PON
Prat Gomà, Josep Joan; Polo Querol, Víctor; Lázaro Villa, José Antonio; Bonada, F.; López Pastor, Eduardo Tommy; Schrenk, Bernhard; Omella, M.; Saliou, F.; Le, Q.T.; Chanclou, P.; Leino, D.; Soila, R.; Spirou, S.; Costa, L.; Teixeira, A.; Tosi-Beleffi, G.M.; Klonidis, Dimitrios; Tomkos, Ioannis (2011)
Text en actes de congrés
Accés restringit per política de l'editorialThe tests with broadband multimedia services of the SARDANA multi-layer prototype prove the feasibility of scalable hybrid DWDM/TDM-PON FTTH networks with resilient optically-integrated ring-trees architecture. -
Wavelength conversion towards Rayleigh backscattering tolerant PONs via four-wave mixing in SOA-based ONUs
Schrenk, Bernhard; Lázaro Villa, José Antonio; Prat Gomà, Josep Joan (2010)
Text en actes de congrés
Accés obertWavelength shifting in PONs with downstream signal remodulation is presented, allowing upstream transmission over trees with 25km feeder and 1:32 split with penalties <2dB, originally Rayleigh backscattering limited. ... -
Wavelength-tuneable remote node for enhanced resilience and optimization of WDM access networks
Lázaro Villa, José Antonio; Bonada Bo, Francesc; Schrenk, Bernhard; Costa, Liliana; Teixeira, Marco Antonio; Chatzi, Sotiria; Klonidis, Dimitrios; Tomkos, Ioannis; Prat Gomà, Josep Joan (IEEE Press. Institute of Electrical and Electronics Engineers, 2011)
Text en actes de congrés
Accés restringit per política de l'editorialA remote node design with a wavelength tuneable optical add/drop element is presented and experimentally demonstrated for application in a resilient ring+tree access network architecture. The flexibility of the network ...
