We use a photon-number-resolving time-multiplexed detector based on a fiber-optical setup and a pair of avalanche photodiodes. By resorting to a germane data-pattern tomography, we assess the properties of the nonclassical light states with unprecedented precision.engjournal articlehttp://0-journals.aps.org.cisne.sim.ucm.es/pra/abstract/10.1103/PhysRevA.90.042105http://0-journals.aps.org.cisne.sim.ucm.es/open access535MeasurementsNon-classical lightsTelecom wavelengthsTime multiplexedÓptica (Física)2209.19 Óptica Física
