Dense Wavelength Division Multiplexing (DWDM) is a key part of the world’s communications infrastructure. The revolution in optical transmission technologies that have occurred in this decade has allowed operators to dramatically increase their transmission capabilities at a fraction of the costs of legacy technologies. For anyone involved with telecommunication and information technology, understanding this technology is of vital importance.

In this introductory DWDM Training – Dense Wavelength Division Multiplexing Training course, you will learn the essentials of the T-carrier system, review the SONET/SDH basics, and study the technology and applications of dense wavelength division multiplexing. Toward the end of the DWDM – Dense Wavelength Division Multiplexing course, we will also touch upon coarse wavelength division multiplexing.
