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
