Abstract :
We propose a novel partial-optical-spectrum degree of polarisation (DOP) measurement that increases the pulse-width dependent differential group delay (DGD) monitoring range for 10, 20, and 40-Gbit/s RZ and sensitivity for 10-Gbit/s NRZ signals. The monitoring range for 20 and 40-Gbit/s RZ signals is extended to one bit time.
