Ever since ancient times, people had a principle need to communicate with one another. This need created interests in device based communication system for sending messages from one distant place to another. Optical communication methods were of special interest among the many systems. In this paper, investigation has been done on two different photodiodes PIN and APD for use as a receiver in free space fiber optical link. We have considered 2.5 Gbps PIN and APD photo diodes for our experiment. From the simulation, we found that APD with single mode fiber gives the better performance over PIN. However, the value of Q-factor is maximum when APD has been used as the receiving photodiode at 1550nm wavelength and minimum when PIN diode has been used as receiving photodiode at 1550nm wavelength. We used OptiSystem and MATLAB software for our investigation
