The Effect of Fiber Bragg Grating (FBG) Sensors on Data Channel of Fiber Optic Communication (FOC) System

Abstract

The advantages of optical fiber sensors, including fiber bragg grating (FBG) sensors, e.g. greater sensitivity, immunity to electromagnetic interference (EMI) and radio frequency interference (RFI), versatility, reliability, compatibility to optical communication and telemetry, reduced cost, reduced size, and reduced weight have been very well known. In particular, the FBG sensors have been widely utilized in many fields such as in structural health monitoring, oil and gas, civil industry, medical and space equipment. In this paper we develop a model of FBG sensors embedded fiber optic communication (FOC) system by using OptiSystem v.18. The bit error rate (BER) and Q-factor analysis as results of the effect of two FBG sensors on telecommunication channels, in which the sensors are integrated into a single fiber optic communication (FOC) with 80 km of fiber optic length. The results show that even with 2 sensors embedded in FOC system, the min BER and max Q factor of the system are still in good conditions with values of 4.35x 10-7 and 4.87 respectively.
