Co-Packaged Optics Market Report Scope & Overview

The Co-Packaged Optics Market Size was valued at USD 91.27 million in 2025 and is expected to reach USD 1,923.64 million by 2035, growing at a CAGR of 35.70% from 2026–2035.

The global co-packaged optics market stands at the frontier of one of the most consequential architectural transitions in data centre and high-performance computing infrastructure design, as the exponential growth of AI training and inference workloads is creating bandwidth and power consumption demands that the established pluggable optical transceiver paradigm is approaching its physical limits to serve efficiently. Co-packaged optics, which integrate optical engines directly alongside switching ASICs or processor dies within a single package rather than attaching them externally through the copper backplane and cage connector interfaces that pluggable transceivers require, addresses the interconnect bottleneck by dramatically reducing the electrical signal path between switch logic and optical conversion, cutting power consumption per bit transmitted by 30 to 50% relative to pluggable transceiver solutions, and enabling the bandwidth density scaling that AI cluster networking at the scale of hundreds of thousands of GPU nodes demands. The urgency of the CPO opportunity is defined by the arithmetic of AI infrastructure growth: training foundation models at the scale of GPT-5 and beyond requires network fabrics that can move exabytes of data between GPU accelerators per day at latencies measured in microseconds, and the thermal density, power consumption, and bandwidth density limits of pluggable transceiver technology are creating hard constraints on AI cluster scale that CPO’s architectural advantages are uniquely positioned to resolve.

Broadcom’s May 2025 third-generation CPO technology announcement supporting 200G per lane data rate, paired with Corning’s collaboration on CPO optical component supply for the Bailly switch and Broadcom’s OFC 2025 ecosystem readiness demonstration with improved thermal management prototypes and OSAT process enhancements, represents the commercial ecosystem crystallisation milestone that hyperscale data centre procurement commitments require before volume CPO switch deployment can begin in earnest.

The U.S. co-packaged optics market was valued at approximately USD 39.61 million in 2025 and is expected to reach approximately USD 834.82 million by 2035, growing at a CAGR of 30.25%. The U.S. co-packaged optics market is positioned to be one of the fastest-growing components of the North American hyperscale data centre infrastructure supply chain, driven by the extraordinary concentration of hyperscale AI infrastructure investment in U.S. data centre campuses operated by AWS, Microsoft Azure, Google Cloud, Meta, and Oracle whose combined AI infrastructure capital expenditure is measured in hundreds of billions of dollars annually and whose network fabric upgrade requirements from pluggable to CPO-based switching represent the most commercially significant near-term procurement pipeline in the global optical networking equipment market.

The United States CPO market benefits from the concentration of the world’s leading CPO technology developers including Broadcom, Marvell Technology, Intel, and Ayar Labs whose R&D centres and initial product commercialisation activities are based primarily in U.S. facilities, combined with the geographic proximity of Silicon Valley’s semiconductor design ecosystem and the hyperscale cloud operator campuses whose early adopter procurement decisions will define the CPO market’s commercial trajectory globally. The U.S. government’s interest in CPO technology extends beyond commercial data centres to include defense and intelligence community HPC applications where the power efficiency, bandwidth density, and size weight and power advantages of CPO-based fabric are particularly compelling for aircraft, shipboard, and ground vehicle computing systems.

NVIDIA’s ecosystem development toward silicon photonics and co-packaged optics integration in next-generation AI switches targeting large GPU clusters, and the August 2025 acceleration of these developments by the wider NVIDIA ecosystem, represents the most commercially consequential CPO adoption signal in the global market given NVIDIA’s dominant position in AI accelerator supply and the company’s ability to define data centre architecture standards through its product ecosystem choices.

By Integration Approach, 2.5D CPO Leads Integration Approach, 3D CPO Grows Fastest

2.5D CPO retained the leading integration approach position in 2025, as the technology’s relative maturity in packaging integration processes, availability of established assembly and testing infrastructure at leading OSAT facilities, and the more manageable thermal co-location challenges of 2.5D configurations relative to 3D stacked approaches make it the deployment-practical choice for the first commercial generation of CPO switches including Broadcom’s Bailly and Tomahawk-based CPO implementations. The 2.5D CPO approach, which positions optical engines adjacent to but not stacked above the switch ASIC on a common substrate, reduces the electrical path between electrical and optical domains relative to pluggable solutions while maintaining the physical separation that enables more conventional thermal management approaches to handle the combined heat generation of both switch ASIC and optical engine components.

3D CPO is the fastest-growing integration approach segment, propelled by the architectural necessity of next-generation AI switch and accelerator designs whose bandwidth density and power budget requirements exceed what 2.5D configurations can achieve, as the shorter electrical paths, higher optical density, and improved thermal coupling that 3D stacking enables translate directly into the superior per-bit energy efficiency and bandwidth density that AI cluster fabric designers are specifying for 2027 and beyond generation infrastructure. The development of wafer-scale integration approaches where optical engines are integrated directly at the wafer level during ASIC fabrication, most prominently pioneered by Intel’s Integrated Photonics Solutions Group and Ayar Labs’s TeraPHY optical I/O technology, represents the leading edge of 3D CPO integration demonstrating the physical interconnect and power efficiency performance levels that the AI computing industry requires to continue scaling cluster bandwidth without proportional growth in infrastructure power consumption.

By Application, Data Centers & HPC Lead Application, Telecoms & Networking Grows Fastest

Data centers and high-performance computing retained the dominant application position in 2025, representing the commercial context in which CPO technology’s value proposition is most immediately and urgently relevant as AI infrastructure bandwidth demands are growing at rates that the pluggable transceiver ecosystem can only partially address through product evolution without the fundamental architectural step-change that CPO integration delivers. The hyperscale data centre operators including AWS, Microsoft Azure, Google Cloud, and Meta collectively represent the world’s most commercially significant CPO procurement pipeline, as their continuous infrastructure expansion programmes require successive generations of switch fabric capability whose bandwidth and power efficiency requirements are the specification targets around which CPO product development roadmaps are aligned.

Telecommunications and networking is the fastest-growing application segment for co-packaged optics, as the bandwidth demands of coherent optical backbone network capacity expansion, 5G transport network densification, and the growing deployment of optical interconnects within telecommunications central offices and edge computing nodes create a growing CPO application space beyond the data centre. The transition of telecommunications network switching and routing equipment toward disaggregated white box architectures whose open hardware designs are increasingly specified to incorporate CPO-based optical interfaces rather than pluggable transceiver cages represents a structural adoption pathway that major telecommunications operators including AT&T, Comcast, Deutsche Telekom, and China Mobile are evaluating as a means of reducing power consumption and increasing bandwidth of their core network infrastructure at a lifecycle upgrade cost comparable to conventional pluggable-based equipment replacement.

By End User, Cloud Service Providers Lead End User, Government & Defense Grows

Cloud service providers retained the dominant end user position in the co-packaged optics market in 2025, as the hyperscale cloud operators’ AI infrastructure capital expenditure programmes constitute the primary commercial demand driver whose procurement timelines, bandwidth requirements, and power efficiency imperatives are directly shaping CPO product development priorities and production ramp schedules across every major CPO technology developer and optical engine supplier in the global ecosystem. The major hyperscale cloud operators’ AI infrastructure buildout is characterised by the unprecedented scale of GPU cluster deployment whose network fabric bandwidth requirements exceed what any previous generation of computing infrastructure demanded, creating the specific CPO adoption urgency that is moving the technology from early adopter commercial availability to mainstream deployment planning across the global hyperscale infrastructure community.

Government and defence represents a growing and commercially distinct end user segment whose CPO adoption motivation is driven by the unique operational environment requirements of military and intelligence community computing systems rather than the commercial data centre cost efficiency considerations that motivate hyperscale cloud operator adoption. The U.S. Department of Defense’s investment in high-density, high-bandwidth computing infrastructure for AI-enabled intelligence analysis, autonomous system coordination, and electronic warfare applications creates procurement demand for CPO-based networking components whose size, weight, and power advantages relative to pluggable transceiver alternatives are particularly compelling in airborne, shipboard, and vehicle-mounted computing contexts where the power budget available for computing and communications electronics is severely constrained.

Market Dynamics

Growth Drivers: AI infrastructure bandwidth crisis creating urgent CPO adoption imperative at hyperscale data centres

The primary structural growth driver for the co-packaged optics market is the mathematically inevitable AI infrastructure bandwidth crisis being created by the exponential growth of AI training cluster scale, where the bandwidth requirements of all-to-all GPU communication patterns during distributed training grow quadratically with cluster size, creating a point within the next generation of LLM training infrastructure at which pluggable transceiver technology’s power consumption and bandwidth density limitations become hard constraints on training cluster feasibility. Broadcom’s demonstration that CPO-based switching can reduce the power consumed by optical I/O in a 51.2 Tbps switch by approximately 2 kilowatts relative to an equivalent pluggable transceiver configuration provides a quantified power saving per switch that, scaled across thousands of switches in a frontier AI training cluster, translates into tens of megawatts of data centre power budget available for additional compute capacity rather than interconnect overhead. Silicon photonics’ manufacturing cost trajectory, aligned with semiconductor foundry capacity expansion and the cumulative yield improvements that production volume experience delivers, is progressively closing the cost premium that CPO-based solutions have historically carried, approaching the breakeven point at which CPO’s power and bandwidth density advantages can be obtained without a significant unit cost penalty that would delay adoption.

Restraints: Thermal co-location management complexity for combined ASIC and optical engine heat generation

A significant restraint on the co-packaged optics market is the thermal management complexity created by co-locating heat-generating optical engine components adjacent to heat-generating switch ASIC dies whose combined thermal output at 51.2 Tbps and beyond creates hotspot densities requiring sophisticated thermal management solutions including targeted liquid cooling and advanced thermal interface materials that add engineering complexity and cost to CPO switch designs. The lack of standardized CPO module interfaces, connector formats, and optical engine specifications across different switch ASIC vendors has historically prevented multi-vendor interoperability, limited procurement competition and creating supply concentration risks that delay volume deployment commitments from hyperscale operators whose supply chain resilience requirements are stringent.

Opportunities: Next-generation AI switch beyond 51.2 Tbps requiring CPO as the only viable interconnect architecture

The next-generation AI switch market at 102.4 Tbps and above represents the commercial transition point at which CPO moves from a premium technical solution to the only commercially viable interconnect architecture for switches whose bandwidth and power requirements exceed pluggable technology’s fundamental capability envelope, creating a mandatory adoption imperative driven by AI cluster scale requirements. The extension of CPO technology to AI accelerator chip-to-chip interconnects, where optical I/O between GPU or TPU dies eliminates the electrical bumping and substrate routing bottlenecks limiting current chiplet interconnect bandwidth, represents a market opportunity substantially larger than the CPO switch market alone and whose realisation would make CPO a fundamental enabling technology for AI accelerator architecture rather than simply an improvement to switch peripheral interface.
