The fiber-based femtosecond optical frequency comb has great potential in the field of fundamental physics and precision measurement. An experimental apparatus for precise control of the fiber-based femtosecond optical frequency comb was discribed. The system was combined with a digital charge-pump phase-locked loop (CPPLL) and a temperature stabilizer. The optical comb system was buit of which the repetition frequency Frep is 129 MHz and the carrier-envelope offset (CEO) frequency Fceo is about 33 MHz. The frequency comb was locked with the standard signal provided by the agilent PSG analog signal generator. The locked state can be maintained over 1 day. The standard deviation of repletion frequency was 0.78 mHz which is the same order of magnitude with reference, and the standard deviation of CEO frequency can be 8.98 Hz.
