CPO is widely regarded as a promising solution for future datacenter interconnections, and silicon platform is the most promising platform for large-scale integration. Co-packaged optics (CPO) is a disruptive approach to increasing the interconnecting bandwidth density and energy efficiency by dramatically shortening the electrical link length through advanced packaging and co-optimization of electronics and photonics. The gap between application requirements and the capability of conventional pluggable optics keeps increasing, a trend that is unsustainable. The conventional pluggable optics increases at a much slower rate than that of datacenter traffic. Furthermore, nearly three-fourths of the datacenter traffic resides within datacenters.

Due to the rise of 5G, IoT, AI, and high-performance computing applications, datacenter traffic has grown at a compound annual growth rate of nearly 30%.
