With CPO, inspecting or replacing faulty optics takes much longer. Worse, a failed optical port embedded in the package means reduced switch throughput, with no easy replacement. These concerns aren't new, but the industry has made significant strides in the last two. Co-packaged optics (CPO) technology, a key enabler for next-generation data center architectures, promises unprecedented bandwidth density and power efficiency by tightly integrating optical engines with switch silicon. But after nearly a decade of existence, where does this next-generation optical. These pressures are driving renewed momentum behind co-packaged optics (CPO). 9B by 2029, fueled largely by AI data centers. This proximity reduces power consumption dramatically. As power consumption continues to surge with the rapid expansion of AI data centers, expectations are high that CPO will dramatically. OFC 2025 made one thing clear: The transition to Co-Packaged Optics (CPO) switches in data centres is inevitable, driven primarily by the power savings they offer.
