Abstract
A CD insensitive PMD monitoring scheme based on measuring RF power is demonstrated experimentally. By using a narrow band FBG notch filter, one of sideband is filtered out and the corresponding RF power can be used as CD insensitive PMD monitoring signal. It is experimentally shown that the proposed method is efficient on measuring the DGD values in 57-Gbit/s D8PSK and 38-Gbit/s DQPSK systems.
