Dispersion Management in Conventional Communication System Using Fiber Grating

Abstract

The interest in faster speed wireless transmission networks is the first step behind the expansion of advanced optical devices. The demand is very assorted starting from low capacity, newlinelow range connections to the ultra-high-capacity transmission system. There is a need for high bandwidth to transmit more data at a faster speed with the advances in communication systems.By establishing the optical networks at low attenuation, a larger propagation capacity can be newlineaccomplished [1]. To attain high bit rates, these networks will be required rapid and efficient system parameters. The recent efforts on developmental and research works are focusing on the advancement of the channel capacity of an optical fiber and enhancing the transmission up newlineto long-distance frameworks utilizing new imaginative advancements. The development in newlinelight wave communication can be synergized by an improvement of effective and an incredible newlineoptical equipment. It deals with the demand for exorbitant changes from light to electrical newlinesignal and vice versa [2]. The information is propagated as a pulse sequence in terms of newlineencoded bits. These encrypted series of data are travelled through fiber without any newlinemodification if noise is less. After travelling for a large distance, the signals begin to stretch, newlinefor which the original shape of the pulse changes. Then the signal gradually overlaps to each other and getting unidentified at the receiver side. The bottleneck problem is still a challenge newlinefor researchers to solve all the dispersion/loss issues. In the last few decades, many innovations have been done by researchers which is imperative to the system. Fiber Bragg Grating (FBG)is one of them and is perceived as the most vital part in optical fiber transmission [3]. In media newlinecommunication frameworks, these are 2 utilized for interference reduction in any channel, for Wavelength Division Multiplexing (WDM) frameworks, and long-period gratings.
