Abstract

We present the experimental validation of a novel technique allowing us to perform in-channel optical signal-to-noise ratio (OSNR) network monitoring by using periodic polarization encoding of the incoming bit stream. The encoding allows us to obtain spectral nulling of the signal and the polarization-mode dispersion (PMD) and not the amplified spontaneous emission (ASE) noise.
