Spectral testing of active optical systems in lab and manufacturing

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.

François Couny

Product Line Manager

François Couny is Product Line Manager for EXFO Optics. He started his career in 2001 as a Test & Measurement engineer at Blaze Photonics, a start-up company specialized in Photonic Crystal Fibre and completed his Ph.D. in Photonics in 2008 at the Centre for Photonics and Photonic Material at the University of Bath (UK). He went on to join Yenista Optics in 2010 with a focus on developing tuneable laser sources and spectral solutions, including an Optical Spectrum Analyzer and also an optical component tester adapted to photonic integrated circuits characterization. Since 2015, François has been PLM for Yenista Optics, now part of EXFO as EXFO Optics.

 

The range of active optical devices such as SFP or QSFP28 is increasing rapidly, thanks to the adoption of many standards and multi-source agreements (MSA) across the telecom industry. With so many devices available, it can therefore become challenging to assess the quality of a transceiver or an amplifier, whether it is for a manufacturer on a production line or for a service provider choosing a transceiver vendor. This challenge is complexified by the fact that all optical transmitters, whether a 100 Gbit/s line card or a pluggable, includes optical subassemblies that generate the optical signal, and each of those subassemblies warrants different kinds of tests. 

This webinar, sponsored but EXFO, will shed light on the testing of active optical devices in manufacturing and lab environments, ranging from the most basic component—the laser—up to complete optical networking systems (WDM or other), including devices like transmitter optical subassemblies (TOSA) and erbium-doped fiber amplifiers (EDFA). More specifically, it will discuss spectral testing, the measurement of optical power as a function of wavelength and related parameters, which is a key part of thorough optical source qualification. For system vendors and service providers, a good spectral testing procedure prevents the use of detective optical modules, which could lead to errors in transmission, useless truck rolls and network downtime. For manufacturers, spectral testing ensures that products delivered to customers are of top quality. This webinar will outline the relevant spectral tests for each type of optical sources and devices. 

What will you learn?

  1. How spectral testing helps increase product quality in manufacturing.
  2. How spectral testing can help choose a transceiver or EDFA vendor.
  3. What the relevant spectral tests are for different types of optical sources and optical amplifiers.
