Abstract :
A novel bit-rate-free and format-free differential group delay (DGD) monitoring technique using a hybrid wavelength converter (WC) as an exOR circuit was proposed. Using this method, the polarization mode dispersions (PMDs) of 40-Gb/s RZ format, 40-Gb/s NRZ format, and 20-Gb/s Manchester format were successfully equalized. The minimum received optical power at a BER of 10-9 was lower than -33 dBm, and the power penalty was less than 0.8 dB. This technique has a possibility to work even for input signal of more than a 100-Gb/s as well as for high-speed burst signal.
