Performance Comparison of FBG as Dispersion Compensator with Different Frequency Chirp in an Optical Fiber Link
Abstract: AbstractRecent day’s optical communication is a most popular technique for transmission of data. We share most of our data through optical network, but the main huddle in performance is dispersion. However, the compensation of dispersion by Dispersion Compensating Fiber (DCF) and Fiber Bragg Grating (FBG) can boost significantly the system. Our proposed work investigates and analyzes the performance of optical transmission system at 1550 nm using FBG as dispersion compensator. …

Performance Analysis of 160 Channel WDM System with EDFA Amplifier
Abstract: AbstractErbium Doped Fiber Amplifier (EDFA) amplifiers are popularly used in wavelength division multiplexing (WDM) system to compensate attenuation and dispersion. The performance of EDFA depends on various parameters such as, EDFA length, Er+3 doping concentration, active fiber length, pump power, pumping wavelength etc. This paper analyzed the performance of EDFA with counter pumping and co-pumping varying the EDFA length, pump power and Er+3 doping concentration and optimized the values for …

A Case Study of Free Space Optic Performance Using Simulation Tools – OptSim
Abstract: ABSTRACTFree space optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. A proper understanding of optical signal propagation in different atmospheric conditions has become essential, and thus there arises the need to rationalize the effects of atmospheric channel on terrestrial FSO links. This paper studies …

Real Time Automation of Boiler Arrangement Using PLC & SCADA
Abstract: An automation system that controls boilers that use PLC, SCADA, and sensors is called a supervisory control along with a programmable acquisition system (PACS). Communication wires were used to link the SCADA and PLC. The first part of the paper discusses how to continuously maintain a particular boiler temperature by feeding the boiler with inputs at the appropriate temperature. Many steps must be taken to go from a manually operated …
