In-line Signal Quality Monitoring based on Asynchronous Amplitude Histogram for NRZ-DPSK Systems

Not Accessible

Your library or personal account may give you access

Abstract

We have demonstrated novel in-service signal quality monitoring technique for constant amplitude NRZ-DPSK signal using asynchronous amplitude histogram evaluation. Information about dispersion and OSNR can be directly extracted from the amplitude histogram of NRZ-DPSK signal.
