Abstract
Fiber group-velocity dispersion and polarization mode dispersion must be dynamically compensated to avoid
performance degradation of optical networks at high bit rates. Precise and reliable dynamic impairment compensation is enabled by optical impairment monitoring. In this paper, GVD and first order PMD monitoring with SOA is demonstrated. XPM is used to monitor the amount of GVD or PMD, whereas SPM allows finding the GVD sign.
