The demand for AI computing power is driving the evolution of high-speed optical modules from 800G to 1.6T, with a focus on precision in packaging. As optical coupling between FAU, lenses, and PICs requires sub-micron control, cross-roller guides are emerging as critical components in this precision upgrade chain.
By 2026, the optical communication industry will still be scaling 800G shipments while 1.6T enters mass production and expansion phases. At the recent CIOE event, several manufacturers showcased automatic coupling equipment for 400G, 800G, and 1.6T silicon photonics, featuring dual six-axis high-precision modules with a positioning accuracy of ±100 nm.
The competition in high-speed optical modules now extends beyond chips and lasers to include manufacturing precision. As optical modules become faster and denser, the tolerances for spatial positioning and angular alignment between fiber arrays, lenses, and silicon chips become increasingly sensitive. The industry will need to monitor advancements in precision motion components, particularly cross-roller guides, to meet these evolving demands.
