Despite TSMC estimating that the mass production of silicon photonic (SiPh) co-packaged optics (CPO) technology will still require more than one to one and a half years, the optical communication industry stated that recent developments in CPO have accelerated. A trial production line is set to begin small-scale shipments in 2025, potentially paving the way for CPO shipments to reach significant milestones in the second half of 2026.
