Underestimated challenges of Remote PHY deployments

Jean-Sébastien Tassé

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. 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.

In the coming years, distributed access architecture and fiber deep trends such as Remote PHY and Remote MAC PHY will greatly transform hybrid fiber coax networks. Remote PHY promises greater capacity for end users, thanks to fiber that will reach deeper into networks (i.e., closer to the end user). Putting so much information on an access network creates new potential issues, some of which are well known (fiber attenuation, dirty connectors, etc.), while others are underestimated. In this webinar, we will discuss two little-known challenges of Remote PHY deployments that can lead to errors in transmission: dispersion—namely, chromatic dispersion and polarization mode dispersion—and protocol layer issues (Ethernet). We will explain these challenges, examine how they can be tested and reveal how they can be overcome. This webinar will also cover Remote PHY testing best practices.

Webinar attendees will learn:

  1. Why dispersion testing should be included in the Remote PHY deployment procedure
  2. How to validate if transceivers being used for Remote PHY are ready for the turnup sequence (SFP, SFP+, QSFP28, QSFPDD.)
  3. The fastest ways to determine if a Remote PHY Ethernet circuit is ready to go live
