Course Overview

This seminar will present WDM Networks, their building blocks and design concepts, aspects of control and management and survivability. A short overview on Optical Access Networks will conclude the seminar. This seminar will complement the “hardware” description of the Optical Communication.

Who should attend?

This seminar is addressed to Telecom Engineers, wishing to get a full understanding of the potential of the emerging Optical Networks. This seminar assumes a basic understanding of Communication Protocols (such as given in the Intro to Modern Data Communications seminar).


Previous participation in the Optical Communication – Technology and Potential seminar is recommended but not mandatory.
