High bandwidth profile based on fiber bragg grating dispersion compensation systems for high bit rate optical communications with long distance links
摘要
This paper presents the high bandwidth profile based on fiber Bragg grating dispersion compensation systems for high bit rate optical communications with long distance links. We have studied the chirp, apodization functions and temperature variations effects on the operation performance efficiency of fiber Bragg grating sensors. The optimum values of fiber Bragg grating (FBG) devices such as power, and reflected signal power can be measured in the presence of Gauss, Tanh parameters variations at different ambient temperatures. FBG operation performance efficiency can be enhanced with the employment of user defined chirp function with user defined apodization function at room temperature in the presence of suitable value of Tanh parameter. It is observed that user defined apodization function has presented the highest FBG power and the lowest reflected signal power in compared with other apodization functions at different types of chirp functions. It is found that the dramatic negative effects of increasing ambient temperature on FGB power, reflected signal power, signal quality factor and bit error rate (BER) measurements.
