Co-Packaged Optics (CPO) Integration and Enhancement with SONiC Switches

Learn about Co-Packaged Optics (CPO) technology and its integration with SONiC in this technical presentation from NTT Devices. Explore how CPO addresses increasing power consumption and transmission quality challenges in high-bandwidth switch ASICs by placing optical-to-electrical conversion closer to the ASIC. Discover insights from the development of a CPO switch compliant with the OIF 3.2T CPO standard, including necessary modifications to existing components and new mechanisms for coordinating external laser sources and optical modules. Examine improvements to SONiC's Virtual Switch environment that enhance transceiver control capabilities, particularly relevant for advanced technologies like 400ZR.
