The aim of this book is to provide a comprehensive idea about high-speed optical communication streams. In recent years, optical devices and other enhanced signal processing functions are also considered in depth for high-speed communications systems. Commonly used optical devices are light emitting diodes and photodetectors. Advances in dense optical communication system is very much useful in telecommunication systems, data processing and networking. It consists of a transmitter that encodes a message into an optical signal, a channel that carries this optical signal to its desired...

Dieses Buch richtet sich an Personen, die sich für die Zukunft der Telefon-, Daten-, Video- und Internetkommunikation interessieren, sowie an Studenten, Wissenschaftler, Designer, Entwicklungsingenieure und Techniker, die mehr über DWDM (Dense Wavelength Division Multiplexing) erfahren möchten. Leser, die im Bereich der Telekommunikation tätig sind, wie z. B. Komponenten- und Systementwickler, können neben dem Text nützliche Referenzen finden. Ich hoffe, dass dieses Buch auch für Wissenschaftler und Ingenieure aus den Bereichen Optik, Spektroskopie, Optronik, Elektrooptik und...

This book is intended for people interested in the future of telephone, data, video, and internet communication, and to graduate students, scientists, designers, development engineers, and technicians who want to learn more about dense wavelength division multiplexing (DWDM). The readers working in the field of telecommunications, such as components and systems designers, may find useful references along with the text. I hope this book will also be useful to scientists and engineers working in the field of optics, spectroscopy, optronics, electro-optics, and micro/nano technology who would be...

The system is simulated and designed for vortex lens based optical wireless communication. As can be concluded from the results and characteristics that the distance could be raised a little bit by employing the vortex lens while comparing with previous studies, based on whose consequences, this system deprived of vortex lens could go up to 600Km to 1000Km and proves its usefulness for Low Earth Orbit Satellites.Although this system also has some failings, as there occur a rapid fall in Q- Factor for 2 sources i.e. half number of sources, but other half number of sources among total sources...

This report proposes a communication system related to free space which work on high bit rate. In optical network there is main advantage it make the communication so easy and effective.in this paper the main goal is it provide large bandwidth along with high data transmission via a communicating link. There is no process or system which has no challenges, here the major challenge is atmospheric disturbances which causes the improvement in bit error rate and reduces the data speed. In this book, the goal is to reduce these effects and makes it more efficient. After analyzing this high speed...
