Intra-channel chromatic dispersion measurements with live neighboring signals in a long haul DWDM system

Tiejun Xia; Glenn A. Wellbrock; Danny Peterson; Wang Lee; Chris Iliopoulos; Jim Cervenka; Fred Heismann

A novel four-tone probe signal is used to measure end-to-end residual chromatic dispersion in single 50-GHz DWDM channels of a long-haul ROADM network while transmitting more than 30 live signals in neighboring channels.

Modified Jones matrix for optical PMD compensation

Fred Heismann

We numerically simulate the average frequency dependence of the coupling that occurs between signal components in the two principal states of polarization and employ our results to define an improved transfer matrix for PMD compensation.
