We develop and demonstrate an experimental cost-effective solution for non-coherent single polarization channel in-band OSNR estimation, using a digital signal processing (DSP) technique, insensitive to effects of different states of polarization. It was verified that previous reported methods when applied in a real optical network scenario (without polarization control), provides an OSNR error estimation above 8 dB when different states of polarization are considered. We analyzed, modeled and implemented this influence through numerical simulations and applied to the experimental device, resulting in a successfully OSNR estimation from 5.5 to 17 dB (range of 11.5 dB) with error below 2 dB for OOK modulated channels.
