The fiber optic technology has been in our lives for a while now. It eases the communication and the transmission of information and it becomes more and more indispensable, especially in the business world. Pin and APD are two different types of photodiodes used in optical communication systems. In this paper, a performance comparison of the conventional PIN photodiode with the Avalanche Photodiode (APD) in an optical communication system is presented. We considered 5 Gbps PIN and APD photo diodes for this purpose. We analyzed bit error rate (BER) and Q factor to achieve this goal. We found that 5 Gbps APD with single mode fiber gives the better performance over 5 Gbps PIN. Similarly, 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 Opti System and MATLAB software for our investigation.
