Yeah, so we're extending from copper into optics for scale-up in three phases: high-density detachable fiber connectors and near-package-optics chipsets both targeting 2027 volume, then fully optically-enabled Scorpio X switches with co-packaged optics in roughly the 2028 timeframe. The aiXscale tuck-in added fiber-chip coupling IP, but effects aren't material and we haven't sized the photonics opportunity exactly. Copper and optical coexist long-term — path runs pluggable to near-package to co-packaged. Remains to be seen how economics play out at scale.
