This study demonstrated the performance of a passively mode-locked fiber laser by optimization of erbium-doped fiber (EDF) length and dispersion compensation fiber (DCF) using Optisystem simulation software. By using different EDF lengths from 1m to 7m, the pulse laser is optimized due to the efficiency of the laser cavity. The DCF length is also varied at 0.001km, 0.01 km, 0.1km and 1 km to observed the performance of mode-locked fiber laser. The system is designed as a single ring cavity by employing a saturable absorber (SA) with 46.5% of saturable absorption. The simulation result shows that the increase of length EDF can generate a narrow pulse width of 2.75 ps at 7 m while the shorter DCF length produced a narrow pulse width at a shorter length 0.001km with 0.36 ps.
