In this research, alternative Raman amplifier configuration were used in a wavelength division multiplexing (WDM)-passive optcal network (PON) system to investigate their effects on channel capacity and signal quality. Because of its scalability, energy efficiency, high capacity, low cost, and flexibility of data transfer ability, various Raman configurations are applied in different position to measure the output power. We used various techniques to evaluate the system performance such as varying the length of an optical fiber from 10 to 100 kms, number of users by increasing 8 to 16 channels. Various channel spacings are utilized in an 8 and 16 channels WDM system to calculate the system's bit error rate (BER) and signal-to-noise ratio (SNR). Another key concern is the high data rate and to achieve the maximum transmission speed. We get the maximum data rate of 128 Gb/s by 8 channels and 192 Gb/s by 16 channels. The maximum BER was 10-9and noise level was -6.35 dBm associated with the distance which was 70 kilometers long fiber channel. Finally, maximum data rate and its related eye diagrams was evaluated.

The wind turbine is a device that is used to harness one of the most abundant renewable energy sources on the planet: wind. It works on the concept of converting wind kinetic energy to electrical energy. Wind turbines are becoming increasingly popular in today's globe since they provide numerous environmental benefits as well as the ability to create enough power for users. A wind turbine's main functioning principle is that it creates electricity when the wind blows. The wind turbine creates more power when the wind velocity is higher. However, regardless of wind speed variations, the goal of this article is to achieve a consistent or controlled output. The goal is to have a controlled output regardless of how quickly the wind blows. This idea is made possible with the help of a converter that is installed within the wind turbine and converts whatever input it receives into a steady, constant, or controlled output. Numerous tests and simulations back up the methods used for this project. The final results that meet the design specifications are compiled and displayed in figures throughout this publication.
