Abstract
As optical networks become more complex, the need for in-line monitoring
of more than just channel wavelength, power and OSNR becomes compelling. In
this paper we describe an asynchronous delay tap sampling technique coupled
with statistical machine learning that enables a single monitor to measure
multiple simultaneous impairments on multiple formats. We demonstrate the
technique for simultaneous measures of CD and 1st order PMD on a 40 Gbit/s
NRZ-DPSK signal.
