Abstract The dark soliton pulse with spectral sideband is experimentally observed in a dispersion-managed all-fiber ring laser with net negative cavity group velocity dispersion. We find that, for single or multiple dark solitons, the spectral sidebands always appear and exhibit asymmetric characteristics which are similar to bright solitons. The experimental measurements of spectral sideband positions are carried out and the results are in good agreement with the calculated values. Our results show that spectral sideband effect is also an intrinsic feature of a dark soliton fiber laser.
