Abstract: Optical fibers have created a revolution in the field of telecommunication and have become the back bone of today's global communication networks. Optical fiber communication is considered to be more advantageous because, it has large channel handling capacity, high signal to noise ratio due to presence of low noise, no electromagnetic interference. In the most recent telecommunication engineering, it is known to use optical fibers for sending optical signals of a predetermined frequency to carry information to be remotely communicated. It is also known that the optical signal sent through an optical fiber undergoes an attenuation during its travel,....

Abstract: The current microwave backhaul systems face numerous challenges including issues related to adverse weather conditions, limited capacity, restricted range and latency concerns. In response to the need for enhanced backhaul performance for 4G (LTE) and 5G networks, operators are increasingly exploring Passive Optical Network (PON) technology as a viable solution. PON technology holds the promise of overcoming these challenges by offering unlimited capacity, minimized latency, scalability, and cost-effectiveness. This research's primary aim is to simulate a designedPassive Optical Network (PON) to serve as the backhaul infrastructure for 4G (LTE) cellular.....

Abstract: The purpose of this survey is to give industry practitioners and readers a deeper comprehension of the high peak-to-average power ratio (PAPR) issue in create a taxonomy of the various ways to alleviate the issue with orthogonal frequency division multiplexing (OFDM) systems. After providing an overview of OFDM systems, the survey goes on to discuss the most frequent obstacle to OFDM systems, the PAPR issue, and how it affects power amplifiers, causing nonlinear distortion. The measures that can be used to assess the effectiveness of PAPR reduction plans are defined in detail in this survey. A taxonomy of PAPR reduction strategies divides them into three categories: coding approaches, signalling and probabilistic, and signal distortion. Within each group, there is further classification......
