Co-packaged optics (CPO) represents the most fundamental rethinking of optical interconnect in decades, moving the optical engine from the switch faceplate to a position immediately adjacent to the switch or accelerator silicon. By collapsing the high-speed electrical path from centimetres to millimetres, CPO overcomes the "interconnect wall" - the widening gap between AI bandwidth demand, which doubles roughly every two years at the switch and far faster for model parameters, and per-lane optical speed, which doubles only about every four years. The technology delivers materially better power efficiency and substantially lower latency than pluggable transceivers, addressing the binding power, density and cost-per-bit constraints of AI data centres.
The market divides into scale-out CPO (network-switch optical engines) and scale-up CPO (GPU and AI-accelerator optical I/O), with scale-up overtaking scale-out toward the end of the decade and becoming the dominant segment thereafter. Adoption begins in the highest-bandwidth network switches, where pluggable modules hit physical and economic limits, and extends into AI-accelerator optical I/O as next-generation GPU platforms ramp.
Recent developments have been decisive. NVIDIA committed to the laser supply chain with major strategic investments in Coherent and Lumentum, and moved its Quantum-X and Spectrum-X Photonics CPO switches toward production. TSMC firmed its COUPE roadmap - a 200 Gbps micro-ring modulator in production in 2026, targeting 4 Tbps/mm bandwidth density by 2030 - while GlobalFoundries launched the OCI-MSA-aligned SCALE platform with 8λ and 16λ demonstrated. Ayar Labs joined NVIDIA's NVLink Fusion ecosystem after a Series E raise; Marvell completed its Celestial AI acquisition; and Fabrinet invested in Raytek Semiconductor. The OCI-MSA (AMD, Broadcom, Meta, Microsoft, NVIDIA, OpenAI) emerged as the de facto scale-up interconnect standard.
Counterbalancing the momentum, large-scale NVIDIA CPO production could slip to 2028–2029 on systems-engineering grounds - serviceability, reliability and manufacturing-test yield - elevating near-package optics (NPO) as a pragmatic intermediate and triggering a sharp sell-off across optical equities. Test and manufacturing scale-up, from roughly one million to tens of millions of units annually, is now seen as the binding constraint, demanding automated, dual-domain electrical-and-optical test cells and standardised optical connectors. The consensus is that CPO's direction is settled; its rate of adoption is the central variable, shaped by yield maturation, field reliability and the pace at which hyperscaler qualification converts into volume deployment across scale-up and scale-out networks.
The Global Co-Packaged Optics Market 2027-2037 is a comprehensive market and technology assessment of co-packaged optics across AI data-centre, hyperscale and high-performance-computing applications. As copper and pluggable optics reach fundamental physical and economic limits, CPO is emerging as the foundational interconnect technology for scale-up and scale-out AI networks. This report provides the data, technology analysis and competitive intelligence needed to navigate the transition.
The report assesses the market from 2026 through 2037, segmented by application (switch CPO and XPU optical I/O), by switch bandwidth generation (51.2T, 102.4T, 204.8T+), by integration technology (2D, 2.5D silicon/organic/glass, 3D micro-bump and hybrid bonding), by component, and by region (North America, Asia-Pacific, Europe, Rest of World). It includes bull, base and bear scenarios with probability assessments, unit-volume and pricing trajectories, cost-parity analysis versus pluggables, and total-cost-of-ownership modelling.
Technically, the report covers photonic integrated circuits and silicon photonics; optical-engine architecture; the benefits of CPO in latency, power and data rate; the 200G-per-lane transition; modulator materials (silicon micro-ring, TFLN, BTO, indium phosphide); wavelength-division multiplexing and the "beachfront" fibre-count constraint; channel-count scaling; the end-to-end optical link budget; advanced packaging (silicon, organic and glass interposers, TSV, hybrid bonding); EIC/PIC integration; laser sources and external-laser architectures; fibre array units and detachable connectors; standards (OIF, OCI-MSA, UCIe, XPO, Open CPX); and CPO test and manufacturing scale-up. It also analyses the full industrial ecosystem and supply chain, including recent consolidation and NVIDIA's supply-chain investments.
