Introduction:
 
Dense Wavelength Division Multiplexing (DWDM) is a key component of the world?s communications infrastructure. The tremendous growth in telecommunications services is possible today in part through optical etworks, where DWDM systems allow much greater bandwidth over existing optical systems. For anyone involved with telecommunication and information technology, understanding this technology is a critical requirement.

In this course you will learn the technology, architecture, and applications of DWDM. We will review DWDM system components as well as the end-to-end optical network design process. You will also learn aspects of optical control, etwork management, and practical deployment issues such as optical submarine cable and access networks. This comprehensive review will provide all the knowledge and skills necessary to design and implement DWDM systems.
 
Audience:
 

The standard presentation of this course assumes a bachelor of science in Electrical Engineering, Mathematics, Physics, or a related subject along with an appropriate background in communications

  • Are you a transmission or network engineer who would like to ?fill in the holes? and catch up with the state-of-the-art of optical systems? Let us know so we can focus on the areas that interest you the most.
  • Are you an optical communications system installer who would like to learn the concepts and theory that underlie your craft? We can focus on the tools and techniques that will help you become more ?tech savvy?.
  • Are you a manager, executive, or sales person whose work involves optical communication systems? If so, we can emphasize those parts of the course that deal with the markets and applications pertinent to your project or product.
  • Add a workshop day at the end of the course, for a total of three days: Get some hands-on practice on an optical simulation and modeling tool to help you with design, procurement, and installation of a DWDM system. We can help you get ready! Please ask us about the ?combo discount?.

Customize it:
 
This 2-3-day DWDM course will be customized to your needs and specifications. Eno.com will assist you in identifying those needs and specifications. A word to the wise, there are many vendors of wireless training. They will typically have a broad and general course, one size fits all, already developed and just put your organization?s ame on the title slide. This minimizes their effort and time investment. At Eno.com, every course is made to your exact and exacting specifications. We help you ensure what you are getting is what you really need even if at the beginning you weren't too sure of what that was. We fit the class to your needs. We never fit you into our standard, one size fits all, class.
