Co-Packaged Optics (CPO) is a technology and design approach where optical components, such as lasers and photodetectors, are integrated alongside electrical components, like Application-Specific Integrated Circuits (ASICs), within the same package. This integration significantly reduces the. Co-packaged optics (CPO) is an approach that aims to address growing challenges around bandwidth density, communication latency, copper reach, and power efficiency in today's data-hungry networks by bringing key elements needed for communication closer together — namely optics and electronics. CPO optical modules put optical and electronic parts together. They make the signal path much shorter, from centimeters to millimeters. This can cut power use by up to half. CPO technology lets more data fit in a small space. However, it's worth noting that Andy Bechtolsheim, co-founder of Arista and a long-standing visionary in data centre. CPO is a network architecture that integrates optical transceivers directly into the same physical package as a switch ASIC or compute processor. As for transmission quality, CPO addresses the problem of overloading.
