From Jensen Huang showcasing CPO switches at GTC 2025 to a wide range of vendors demonstrating optical engines integrated inside ASIC packages at OFC 2025, CPOs are everywhere. Even as SerDes speeds increase, copper-based links struggle to deliver the required bandwidth per watt, once equalization and retiming overheads are factored in. Third, distance itself has become a problem: latency, energy per bit, and signal integrity degrade sharply with electrical reach. Silicon photonics (SiPh) offers a high degree of integration and cost-effectiveness, helping to enhance optical module performance while driving down costs. Coherent technology facilitates long-distance, high-speed transmission with exceptional signal quality. 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.
