In this paper, we report the stabilized 10-GHz actively mode-locked fiber ring laser constructed with non-polarization-maintained fiber. Long term stabilization was achieved by synchronous modulation technology, based on an error signal extraction and procession circuit. The output pulses maintained very well over 8 hours with the pulse width of ～11 ps and the spectrum width of ～0.37 nm. Meanwhile the output power and the center wavelength of the output pulse also kept stable at 1.6 mW and 1550.3 nm respectively. The output pulses were additionally compressed to 2 ps by high order soliton effect.
