DWDM Advanced Training Course Description

In this DWDM Advanced Training 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. With DWDM Advanced Training, you will also learn aspects of optical control, network 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.

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.

Customize It:

• If you are familiar with some aspects of this DWDM Advanced Training course, we can omit or shorten their discussion.
• We can adjust the emphasis placed on the various topics or build the 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 course in manner understandable to lay audiences.
