Abstract
This paper presents the performance analysis of fiber Bragg gratings with diverse chirp profiles in compensating chromatic dispersion in wavelength division multiplexed long-haul optical fiber systems. The method employs multistage pairs of circulators and tanh-apodized fiber Bragg gratings with different chirp profiles. The research studies the performance achieved by the combinations of different chirp functions to effectively tackle the impacts of chromatic dispersion in long-haul optical fiber communication systems. The study examines the system performance, considering different transmission distances, channel spacings, and transmitter power levels. Comparative scrutiny is also performed to analyze the impact of three different modulation schemes on the chromatic dispersion compensation technique. The results also demonstrate that the proposed approach brings about exceptional compensation of chromatic dispersion over long-haul spans exceeding 100 km with constricted channel spacings of 50 GHz and 25 GHz and also at input power levels as low as −15 dBm. These discoveries suggest that the proposed technique is a promising strategy for addressing chromatic dispersion in long-haul optical fiber communication systems, enabling reliable and efficient data transmission over extended reaches.
