Product Manager

Jean-Sébastien Tassé has more than 13 years of experience in sales and marketing in the high-tech sector. 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.

Dispersion, if not properly tested and managed, can have very serious impacts on system performance ranging from sporadic errors to systematic failures.

This advanced webinar will discuss key concepts related to dispersion (e.g., chromatic dispersion, polarization mode dispersion or PMD, material dispersion, differential group delay and birefringence), as well as the thresholds for optimal network operation. In addition, it will examine the main criteria used to determine whether dispersion testing should be performed on a link, and review the typical network types in which dispersion should be tested—both in terms of distances and data rates. The webinar will conclude with a case study on dispersion testing. Although no prior knowledge about dispersion is needed to view this webinar, please note that the focus will be on more advanced topics.
