POLARIZATION MODE DISPERSION COMPENSATOR PARALLEL MONITORINGAND CONTROL ARCHITECTURE |
摘要 |
A parallel monitored and controlled optical PMD compensator comprises a bran ch optical signal split from an optical signal path. A polarization controller (PC) and differential group delay are disposed in each of the paths. A controller adjusts polarization compensation of the PCs in response to PMD dispersion of the branch optical signal. A PMD monitor is preferably disposed in the branch path providing a monitor signal to the controller for use in adjusting the PCs. A polarization rotator may inject a reference signal into the paths with the PC disposed in the branch path acting as a polarization scrambler. A state of polarization (SOP) of the reference signal may be monitored by polarimeters disposed in both paths and the SOP of the reference signal in the branch pat h may be provided to the controller for adjusting polarization compensation of the inline PC.
