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 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 Training – Dense Wavelength Division Multiplexing Training course, we will also touch upon coarse wavelength division multiplexing.

Upon completing this WiMAX Traffic and Capacity Engineering Training course, learners will be able to meet these objectives:

  • Describe the major components of the mobile network architecture, including signaling, and how they work together
  • Describe how different services place different demands on the network and affect the utilization of resources
  • Model and predict the impact of network capacity requirements on varying applications and diffusion curves
  • List all the packet models relevant to WiMAX and Mobile WiMAX services
  • We can customize the DWDM – Dense Wavelength Division Multiplexing course to address the concerns unique to the various audience groups including transmission, network, or systems engineers, chipset manufacturers, R&D specialists, optical system installers, managers and executives, marketing and sales personnel, operations, and support personnel, and others. Most customization is performed at little to no added cost.
  • If you are familiar with some aspects of this DWDM Training – Dense Wavelength Division Multiplexing course, we can omit or shorten their discussion.
  • We can adjust the emphasis placed on the various topics or build the DWDM – Dense Wavelength Division Multiplexing course around the mix of technologies of interest to you (including technologies other than those included in this outline).
  • If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the DWDM course in a manner understandable to lay audiences.

The target audience for this DWDM training course:

  • Telecommunications transport, systems, and network engineers, capacity managers, and others responsible for the planning, design, or day-to-day operation and management of large telephony systems.

 The knowledge and skills that a learner must have before attending this DWDM Training course are:

  • While there are no particular prerequisites for this course, some comfort with Physics and Mathematics will be helpful. However, all necessary Mathematics/Physics concepts will be reviewed within the course as needed.
