DWDM and Optical Networking for Metro and Long Haul

After completing this course, participants will be able to:

  • Understand technologies and concepts that underpin DWDM and optical networks
  • Name the key components of optical networks and how they fit together
  • Explain advanced DWDM network design principles and operation
  • Appreciate the effects of noise in signal propagation e.g. OSNR
  • Grasp the key test and measurement parameters in optical systems and DWDM networks
  • Understand optical networking in metro and long haul environments
  • Design optical network transport systems suitable for metro and long haul

Course Overview:

This advanced level course opens with some ‘refresher activities’ before considering some of the more advanced aspects of DWDM network design and engineering – its focus is on Metro and Long Haul optical networking.

Cisco predict that by 2020 there will be 50 billion objects connected to the Internet – metro and long haul optical transport networks are central to this Internet of Everything vision.

Participants are taught the design principles of optical networking before being afforded the opportunity to design optical links based on a number of different criterion.

An insight into the key test and measurements applicable to various optical systems and DWDM network applications is offered.

Pre-Requisite for Participants:

A working knowledge of optical fiber and DWDM technologies.
Prior attendance at Course C1: SDH/DWDM Fundamentals.
Prior attendance at Course C2: From SDH to Optical Transport Network.
Prior attendance at Course C3: Optical Transmission Planning and
All HIGHLY desirable.

Who Should Attend?

This course is designed for fiber core supervisors, planners, technicians and professionals, strategic and technical telecommunications managers, consultants, IT professionals, systems engineers, software engineers, marketing and sales personnel plus other telecommunications workers who plan on using, evaluating or working on DWDM and optical networking in metro and long haul scenarios.

Course Duration:
