A new but simply implemented optical clock recovery scheme for optical time-division multiplexing (OTDM) systems based on stimulated Brillouin scattering (SBS) effect is presented and demonstrated experimentally.According to the unequal-amplitude even-multiplexed OTDM signals,the frame clock is extracted.In addition,the clock with multiple tributary rates is recovered from 160-Gb/s OTDM signal in simulation by utilizing the clock recovery module.
