Abstract
This paper addresses the problem of monitoring
of fiber nonlinearities in WDM based passive optical
networks. This technique is based on positioning and
characterizing a probe channel which is further analyzed.
This analysis leads to an estimation of the nonlinear
distortion in the system which in turns could be used for
instance to optimize the system performance. This technique
is validated through simulation results.
