To promote the broadband fiber source temperature stability, the mean-wavelength stability of broadband fiber source was analyzed and the dependence between the mean-wavelength and the output optical power was revealed based on the simulation and experiment study on the change of mean-wavelength and output power under different pump optical power. A mean-wavelength control scheme was proposed based on the dependent mathematical model among with mean-wavelength, feedback power and environmental temperature by temperature experiment. The mean-wavelength precision control was realized by taking small part power from fiber source output as feedback signal and adjusting the pump power by changing drive current. A prototype fiber source was made and tested. The result approves this scheme and 0.3×10-6�Q�Q��-1 mean-wavelength stability within -45~70�Q�� was achieved.
