摘要
A novel technique for optical labeling of payloads and labels using optical single-sideband modulation is proposed. This method can effectively reduce the bandwidth of optical signal and utilize the low frequency RF devices to generate the labels. And we also investigate the power and phase character of this scheme. Simulation results show that this scheme is robust to the phase differences of the single-sideband payload and label. After fiber transmission and label swapping, the power penalties of payload and label are both less than 1dB. Therefore this scheme is suitable for 40Gb/s optical label switching networks.
