The article re-frames Co-Packaged Optics (CPO) as a system limited by energy, heat, and reach, not just optical supply chain factors. Its volume ramp is contingent on the simultaneous readiness of 800V power, liquid cooling, external-laser reliability, and optical-engine qualification. Value is expected to migrate toward external laser sources (ELS), optical engines, foundries, and fiber interfaces, with DSP and copper potentially earning the most immediately.
Co-Packaged Optics deployment is a multi-factor constraint problem, shifting value to power, cooling, and optical engine suppliers, not just traditional networking components.
