Abstract

We evaluate the asynchronous Q factor from a dense-wavelength-division-multiplexed (DWDM) optical signal distorted by chromatic dispersion, amplified-spontaneous-emission noise, nonlinear effects, and intersymbol interference, using amplitude histograms. It was experimentally confirmed that the asynchronous Q factor is related to the signal-to-noise ratio obtained from the bit-error-ratio (BER) measurement on the same channel realized by the optical receiver. We also propose a model for direct assessment of the BER of a DWDM optical signal from the asynchronously detected amplitude histograms. The obtained experimental results indicate that this method can monitor the signal-performance degradation, confirming the applicability of this technique as optical performance monitor for transparent photonics optical networks.
