He currently holds the position of Product Line Manager in EXFO’s optical business unit, where he oversees the business strategy, roadmap and launch strategy of the optical spectrum analyzer and dispersion product lines. At EXFO, he is also business development manager for the market segments of submarine networks and fronthaul/backhaul networks (optical products). He began his career as Sales Engineer for Gentec Electro-Optics, where he was responsible for direct and channel sales in specific regions in the Americas, Asia and Europe. As Business Development Manager for the Thin Film Research Laboratory at the École Polytechnique de Montréal/University of Montreal, he was instrumental in delivering revenue growth in analytical services for companies. Jean-Sébastien holds a bachelor's degree in Engineering Physics and a master’s degree in Electrical Engineering (optics) from Université Laval, in Québec City, Canada.

Thanks to the advanced algorithms, coherent systems promise to compensate for PMD in real time. However, do they actually deliver on that promise?

In this webinar, EXFO (a leader in field testing), and General Photonics (an expert in lab measurements) join forces to explain the reasons why PMD compensation might fail or be ineffective. Also, some recommendations are provided on how to reduce the risks of these failures. This webinar will cover the following topics:

  • The concepts of PMD, Differential Group Delay (DGD), and State of Polarization (SOP)
  • The limitations of PMD compensation capabilities in coherent receivers
  • The PMD-related tests performed in the laboratory to optimize PMD compensation algorithms
  • The PMD tests carried out in the field to identify PMD issues in advance and reduce their frequency
