Lightmatter unveils Passage L20 photonic interconnect, announces vClick Optics offering for high-volume CPO manufacturing. Launches aimed at supporting transition towards multi-rack scale-up and high-bandwidth scale-out in AI data centers March 12, 2026 Photonic computing company Lightmatter has unveiled the Passage L20 interconnect, designed to support the transition towards multi-rack scale-up and high-bandwidth scale-out in AI data centers. The company has also launched vClick Optics. Described as the industry's first detachable fiber array unit (FAU), it helps to overcome scaling challenges associated with co-packed optics (CPO) in high-volume manufacturing environments. - Charlotte Trueman Companies will be able to integrate vClick Optics directly into the wafer fabrication process to allow for earlier testing and validation in the product development lifecycle. Known as "shift left," this approach has been found to reduce costs and improve yield across 3D-integrated circuits, chiplets, and CPO manufacturing. According to Lightmatter, the advantages of vClick Optics include high bandwidth DWDM and advanced packaging compatibility, automated assembly that removes the requirement of active fiber alignment, and field serviceability. California-based Lightmatter specializes in photonics-enabled technologies that use light instead of electrical signals for computing...
