An all-fiber optical homodyne tomography setup is introduced that measures the optical signal-to-noise ratio through reconstruction of the photon statistics. The scheme described has been conceived for applications to optical communications. In particular, the signal-to-noise ratio has been evaluated at λ=1.55 μm as a function of the received power. From the experimental data, in the case of optically amplified signals, the amplifier noise figure can be estimated.
