Course Objectives

As most of the people in Telecom industry would agree, a healthy optical industry is critical so that it can ensure that innovation continues for the long-term.

DWDM (Dense Wavelength Division Multiplexing) is such a ubiquitous technique that is used in the optical networking system to make sure the industry as a whole remains profitable and healthy so we can continue driving the major data transition rates that are desperately needed to keep up with global bandwidth demands.

Telecontran’s Advanced DWDM workshop would not only cover the architecture and applications of DWDM, but also focus on multiple aspects of optical control, network management, and practical deployment.

After successful completion of this workshop, participants will be able to

  • Understand advanced optical communications topics as well as advanced DWDM Network Designs and Engineering
  • Describe the detail architecture of a DWDM network and Design a DWDM system
  • Learn about the effects of noise in signal propagation, especially from OSNR and BER perspectives
  • Describe the key considerations related to the deployment of DWDM
  • Learn how to design optical links based on power budget, dispersion and non-linearties Design optical links based on OSNR
  • Design DWDM networks based on size and performance
  • Learn how to test and measure different parameters in DWDM networks
  • Learn about MPLS and MPLS VPN and how to use MPLS efficiently in DWDM and Optical Networking system.

Target Audience

This course is specially designed for strategic or technical managers, consultants, communications professionals, system engineers, network professionals, IT professionals,especially Transmission Engineers who are involved in planning and designing of DWDM and optical networks applications and services.
