Exemplary Advancement of EPON Communication by FBG based Splitters


Objectives: In the last few years, researchers in the field of optical fibre communication have focused on designing optical filter for blocking certain wavelength using Fiber Bragg Grating (FBG). In this paper inculcates the study and research on FBG base splitters with alteration of grating length for Ethernet Passive Optical Network (EPON) is carried out. Methods/Analysis: The simulation is incorporated on simulation Software MATLAB 7.2 of Mathworks. The simulation model is constructed by varying design parameters such as grating length, which in turn attains the maximum reflectivity for the wavelengths required for EPON. We fix the values of the effective refractive index of grating and radius of the core. Here the grating length and centre wavelengths are fixed 35 mm and 1550 nm respectively and findings obtained. Findings: FBG is one of the renowned distributed Bragg reflector manoeuvred in an optical fiber of small segment and it possesses the stupendous attribute of reflecting particular wavelengths of light whilst traversing all other wavelengths. As per observations the reflectivity of the grating or the effectiveness of the grating in extracting the wavelength has a tremendous value of 100%. This filter has various applications which improve the quality and reduce the cost of an optical network.
