A new-type controllable slow light system based on a multi-stage delay Stimulated Brilliouin Scattering (SBS) structure is proposed. In this experiment, a shorter fiber (600 meters) is used to raise the Brillouin thresholds, and the pump power is also increased, therefore the unsaturated gain and the single-stage delay effect are enhanced. Moreover, the two fiber segments of slow light delay are cascaded by two circulators in the configuration, which can increase the delay time and the utilization rate of stokes signal during the experiment, the signal light which the power is-15dBm has acquired 51.299dB gain and the delay time is 55.333ns. Compared with the single-stage delay, the delay time has been increased.
