Abstract :
We propose and experimentally demonstrate using polarization-nulling with off-center narrowband filtering to monitor OSNR for 10-Gb/s and 40-Gb/s RZ signals. Robustness to PMD is significantly enhanced compared with prior polarization-nulling scheme without employing narrowband filtering.
