This course covers
  • WDM systems
  • OSA test software: configuration and use
  • Automated test procedures
  • Examples of common OSA test procedures
  • Critical parameters:
    • Peak power
    • Central wavelength
    • Channel spacing
    • Optical signal-to-noise ratio (OSNR)
  • OSA configuration for system qualification
  • Test configuration for WDM component testing
  • EDFA testing
  • In-band testing and true OSNR


Basic comprehension of math and physics
Basic fiber optics and loss testing (IL and ORL)


The first part of this course consists of lectures using PowerPoint presentations and demonstrations, while the second part consists of specific hands-on OSA testing exercises and experiments on critical parameters measurements for WDM systems.


Attendees will receive a binder containing copies of presentations and other handouts.
