We report a long term stabilized 4th order rational harmonic mode-locked (RHML) erbium doped fiber laser operating at 40Gb/s. The cavity length drift induced laser instability is overcomed by constructing a modified regenerative type feedback loop to actively adjust the modulation frequency of the 10GHz driving signal. The 4th RHML fiber laser is tested to be highly stable against environmental perturbations.
