The relationships between OSNR, electrical SNR and BER at the receiver are experimentally analyzed and compared to theoretical results. A linear dependency in dB is found between electrical SNR and subcarrier OSNR for total OSNR values below 26 dB. Above this limit, the correlation degree decreases due to the electrical SNR degradation at the edge subcarriers. The BER analysis per subcarrier also shows a clear correlation with the proposed in-band optical measurements. 000149827 536__ $$9info:eu-repo/grantAgreement/EC/FP7/317999/EU/Industry-Driven Elastic and Adaptive Lambda Infrastructure for Service and Transport Networks/IDEALIST$$9info:eu-repo/grantAgreement/ES/MICYT/TSI-020100-2011-423$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2012-38119 000149827 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttps://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 000149827 590__ $$a1.48$$b2015 000149827 591__ $$aOPTICS$$b51 / 91 = 0.56$$c2015$$dQ3$$eT2 000149827 592__ $$a0.673$$b2015 000149827 593__ $$aElectrical and Electronic Engineering$$c2015$$dQ1 000149827 593__ $$aPhysical and Theoretical Chemistry$$c2015$$dQ2 000149827 593__ $$aElectronic, Optical and Magnetic Materials$$c2015$$dQ2 000149827 593__ $$aAtomic and Molecular Physics, and Optics$$c2015$$dQ2 000149827 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000149827 700__ $$0(orcid)0000-0002-4094-3826$$aSevillano, Pascual$$uUniversidad de Zaragoza 000149827 700__ $$aSvaluto Moreolo, Michela 000149827 700__ $$aVillafranca, Asier 000149827 700__ $$aVílchez, F.
