Ciena Corp. (CIEN) surged 9% in late trading, marking one of the strongest performances among tech hardware names, as investors reacted to renewed optimism around global data infrastructure upgrades. Lumentum Holdings Inc. (LITE) followed with an 8% rise, while Coherent Corp. (COHR) advanced 7%, signaling broad-based momentum across the optical components and subsystems space. The rally underscores growing market conviction in the long-term demand for high-speed optical networking equipment, particularly as hyperscalers and telecom providers accelerate deployment of AI-optimized data centers. These companies supply critical components such as lasers, modulators, and transceivers essential for next-generation fiber-optic networks, which underpin AI training and cloud computing workloads. The trio’s gains contributed meaningfully to the broader Nasdaq Composite (^IXIC), which posted a modest uptick on the day, with technology stocks accounting for over half of the index’s daily advance.
