Ligitek skips 800G, targets 1.6T silicon photonics

By bypassing the 800G standard and targeting 1.6T silicon photonics, Ligitek signals a rapid evolution in AI data center optical module architecture. This move will accelerate upstream developments in silicon lasers, driver circuits, and packaging materials, while pressuring downstream engine vendors to upgrade. From a compliance standpoint, enterprises in China Taiwan/ Taiwan, China involved in high-end modules face heightened export controls and supply chain scrutiny, raising operational costs. Competitors like Broadex and Hisense may accelerate 800G product cycles or retreat to lower-tier markets. In the longer term, commercialization of 1.6T/3.2T modules will drive AI compute demand toward higher bandwidth, reshaping the entire photonic interconnect ecosystem toward greater integration and energy efficiency.
