Title:
Comparative Study of an Optical Link with PIN and APD as Photo-Detector
Author Name:
Preetam Jain, Dr Lochan Jolly
Abstract:
ABSTRACT Exchange of information between any two devices across a communication channel involves using some type of electrical or optical signal which carries the information. Parameters considered while analyzing the optical link are desired transmission distance, data rate or channel bandwidth and BER. This paper presents variation in the BER with the change in the transmission distance and the length of the fiber considering the photo-detector as PIN and APD. With the increase in length of the fiber and transmission data rate, dispersion increases. Hence, optical signal incident on the detector is below the required sensitivity power requirement and system is not able to give the electrical output. APD with single mode fiber gives the better performance over PIN. Keywords: PIN; APD; BER; Q-factor
