Chromatic Dispersion Compensation in Optical Fiber Communication System using FBG and EDFA
Abstract: AbstractNowadays optical communication is a most significant technique to transmit the data. In daily life we share our useful data by using optical network but dispersion is the main factor towards limiting the performance of optical system. However, the compensation of dispersion by Dispersion Compensating Fiber (DCF) and Fiber Bragg Grating (FBG) can boost significantly the system. This proposed work investigates and analyze the chromatic dispersion compensation in optical fiber …

Machine Learning Based Optimization of Optical Fiber Parameters for Minimizing Dispersion and Attenuation
Abstract: Optical fibers provide high-bandwidth and low-loss transmission for modern communication networks; however, attenuation and chromatic dispersion remain two important physical limitations affecting transmission distance, pulse integrity, and system capacity. Conventional optical-fiber design generally relies on analytical calculations and repeated numerical simulations to determine suitable geometric and material parameters. Such approaches become computationally demanding when several fiber parameters are simultaneously optimized. This paper presents a machine-learning-based methodology for predicting and optimizing …

Design and Simulation of an Optical Fiber Communication System Using MATLAB
Abstract: Optical fiber communication is widely used for high-capacity data transmission because of its large bandwidth, low attenuation, immunity to electromagnetic interference, and support for wavelength-division multiplexing. These properties make fiber a fundamental medium in access, enterprise, submarine, and backbone networks, where high data rates, low error probability, and reliable transmission over distances ranging from buildings and campuses to metropolitan and long-haul links are required. This paper presents a MATLAB-oriented design …

A Comprehensive Review on Comparative Study of Different Techniques of Dispersion Compensation
Abstract: AbstractOptical fiber communication (OFC) provides high bit rate data communication. There are various types of impairments and signal degradation mechanisms which are involved with this highspeed communication system. In case of long distance communication, the most prominent impairment is dispersion. Dispersion affects the information signal very badly when it travels along a long distance. There are different techniques available to compensate dispersion. In this paper, the various methods of dispersion …

Design and Performance Analysis of Silicon Photonic Waveguides for High-Speed Optical Communication
Abstract: The exponential growth of data traffic in data centers and high-performance computing systems necessitates a paradigm shift from conventional electrical interconnects to high- speed, low-power on-chip optical interconnects. Silicon Photonics (SiP) is the leading platform for this transition due to its compatibility with CMOS manufacturing and the high- index contrast between silicon (Si) and silicon dioxide (SiO 2 ). This paper details the design, simulation, and comprehensive performance analysis of …

Evaluating Novel Inhibitor Pigment Blends using Electrochemical Scanning Techniques (EIS, SVET and SKP)
Abstract: AbstractOne of the main applications coming to the fore for scanning vibrating electrode technique (SVET) and scanning Kelvin probe (SKP) systems is ability to look at inhibitor combinations, which could be used to replace chromates in coil-coated galvanized steels. The results are very promising using the SVET system and results with the SKP system also show results to be comparable with the SVET system. Electrochemical impedance spectroscopy (EIS) is also …
