A novel vestigial-sideband (VSB) payload scheme is proposed for high-speed all-optical label-switching (AOLS) networks. The combination and separation of the VSB payload and the optical label is experimentally demonstrated, and the influences of the power-split ratio, time-delay interference, interferometric noise (IN), and wavelength difference between the payload and the label are analyzed. Simulation and experiment results show that this VSB payload scheme can highly reduce the channel bandwidth and it is easy to realize by using optical filters, so it is a potential technique to be used in optical networks with bit rate of 40 Gb/s.
