Marvell showed 2nm optical technologies at ECOC 2026 in Malaga, Spain, including 400G-per-lane optical PAM4, an 800G ZR/ZR+ pluggable with MACsec and 1.6T coherent-lite links. The products are aimed at 3.2T AI data center links, but the release only offers live demonstrations and does not give shipping dates. Investors should read it as a roadmap signal.
