Secured Data Transmission in Multiplexing System

The transmission of numerous optical wavelengths across a single cable is made possible by a method known as dense wavelength division multiplexing, or DWDM for short (Dense Wavelength Division Multiplexing). Because of recent technical developments in the use of lasers, it is now feasible to achieve bandwidth increases for already-established fiber-optic backbones. It makes it possible for signals of a range of wavelengths to be sent simultaneously using fiber optic networks. A DWDM system cannot function without the Mux and the Deux, which are two components that are necessary for its functioning. Using combinational logics such as multiplexers and decoders, the data that will be discussed in this article will be sent and received in a sequential form (de-mux). For the sake of the implementation, both the multiplexer and the decoder will each be given their own separate Verilog files to be written in. To set up a communication system that uses serial signals, an extra Verilog file will need to be created. This file's purpose is to hide the fact that the multiplexer also functions as a transmitter and that the decoder also functions as a receiver. The counter is wired up to the circuit so that it may be manipulated by the user to achieve the desired state of synchronization. With the help of this hybrid design approach, design complexity can be better managed, parallel development can be carried out, and reliable communication can be fostered. The wireless communication system must have high throughput communication that is spectrum efficient, power efficient, and cost effective to enable communication for ubiquitous applications such as speech data image video movies. multimedia services GPS stands for Global Positioning System. telemedicine, the Global Positioning System (GPS), and other forms of value-added communication Within the first category, an examination of spectrum efficiency is carried out using a variety of modulation schemes and various access methods. This is known as the Quadrature Phase Shift Keying. OFD and QPSK are two types of frequency division techniques. Combinations of multiple access and OFDMA are investigated for their effects on data rates. However, throughput is decreased because of a variety of interferences, including in-band interference, out-of-band interference, and others. Inter Symbol
