Optical Networking Digital Symposium Session 1: Telecom Opportunities for the AI Wave  The AI optics boom is expanding beyond hyperscaler data centers. In November, for example, Lumen announced $8B in custom fiber deals with Microsoft, Google, Amazon, and Meta, along with 10% of Corning’s global fiber output for two years. As AI shifts from model training to inference (i.e., using the models), demand for optical connectivity is accelerating across a diverse ecosystem of CSPs, enterprises, content providers, and more. Speakers explored how networks must evolve to meet these needs both today and tomorrow.  This session was part of Light Reading’s Optical Networking Digital Symposium. Moderated by Sterling Perrin, Principal Analyst, Heavy Reading. Specific topics discussed in this session include:  CSP AI-driven requirements in metro and long-haul networks Automation use cases to support AI demand Meeting AI inferencing needs at the edge Network requirements to support emerging AI exchanges Addressing capacity, space/power, and security challenges Optical line system technology evolution Watch this informative on-demand session with EXFO’s Francois Marcotte together with industry leaders from Telefonica, Lumen, Verizon and 1FINITY. 

From humble beginnings as a small startup to a global leader in telecom test and measurement, EXFO proudly marks its 40th anniversary under the theme Innovation, Disruption, and Market Leadership.

As transceivers scale to 400G, 800G and coherent technologies, they’re becoming more expensive—and more critical to get right. But many so-called "defective" optics aren't defective at all. In this webinar, sponsored by EXFO and the TIA’s Fiber Optics Technology Consortium (FOTC), we’ll explore why validating transceivers before deployment and during operation is essential for high-performance, reliable data center operations. From cleanliness and compatibility checks to full functional testing, fast diagnostics can prevent unnecessary replacements, avoid downtime, and reduce costs. You’ll also see how transceiver validation testing tools automate validation across thousands of pluggables—ensuring real performance and multi-vendor compatibility. Plus, learn how detailed test reports can provide actionable insights—empowering your team to make informed deployment decisions and engage in data-driven discussions with transceiver vendors. What we’ll cover: Why validation is critical with 400G, 800G, and coherent optics How to detect issues early—cleanliness, compatibility, and performance The high cost of trial-and-error replacements How to streamline validation—quickly and at scale How automated test reports support better decisions and vendor accountability
