The Role of CPO Optical Modules in AI Computing Power

CPO, a technology that deeply co-packages the optical engine with the switch chip, offers a solution for next-generation AI cluster interconnects by shortening the signal transmission path, reducing power consumption, and increasing bandwidth density. The image below shows a conceptualized AI compute tray with CPO developed with products from SENKO Advanced Components and Marvell. The design contains room for four XPUs and up to 102. 4 Tbps of bandwidth delivered through 1024 optical fibers, all in a 1U tray. The density and reach enabled by CPO. Successful CPO designs require architects to think in multi-physics terms, balancing electrical signaling, thermal stability, optical behavior, and mechanical constraints at the package/system level. It is not just an optical module technology. That playbook is no longer holding for today's AI systems. As AI clusters push beyond 100 Tb/s per node, the gap between what silicon can generate and what traditional copper interconnects can deliver is widening fast. By leveraging advanced packaging technologies such as 2. 5D or 3D integration, CPO reduces electrical path lengths.
