DWDM Networks Tutorial

What you’ll learn

This course is for students and professional keen in learning DWDM network and it components. This course is useful for basic to advanced level.
Basic of optical fiber communication, signal impairments i.e. absorption, scattering, dispersions, Kerr effect. We also cover different subsystems in photonics and their fundamentals.

DWDM Networks Tutorial


Basic understanding of networking and optical transport system


This course is devised for professionals and students who wanted to understand DWDM network architecture. We start our journey by understanding our signal carrier that is light. We learn which particular band of light is used for fiber communication and why. We learn about DWDM technology. We also learn about all the different types of impairments in fiber optics communications. We have one complete section devoted to all the components used in DWDM. We talk about ROADM its architecture and types in great detail. We also touch on flex and fix grid technologies.
