Based on 2 ×2 optical fdber couplers, a simple novel Maeh- Zehnder interfemmeter sysetm was presented. And the effect of Fusion- Elongation couplers parameters on stability of the Mach- Zehnder interfemmeter system and the output optical intensity of the interferometer were also analyzed. The experiment found that the vibration is slow in a period of 3× 0.32 min and phase drift is at the rate of 2.82 rad/min.
