Lumentum’s 200G electro-absorption modulated laser (EML) is our next-generation product for high-density, energy-efficient optical connectivity. Each device pairs a wavelength-locked DFB laser with a single-ended electro-absorption modulator (EAM) to deliver clean 200G-per-lane transmission with low power consumption. Designed for CWDM4 operation at 1271, 1291, 1311, or 1331 nm, it supports 115GBd PAM4 signaling for 200G-per-lane transmission in DR and FR links up to 2 km. The 200G EML provides high bandwidth, high extinction ratio, and stable performance under datacenter thermal conditions. Built on our InP platform proven in reliability and manufacturability, it enables scalable 1.6T pluggable transceivers with eight 200G lanes, meeting the speed, power, and reach demands of next-generation AI and cloud data center architectures.
