The rapid expansion of artificial intelligence infrastructure is increasing the demand for high-bandwidth, energy-efficient data transmission between processors, switches and computing systems. As conventional electrical interconnects face growing challenges at higher data rates, co-packaged optics (CPO) is emerging as an important approach for bringing optical connectivity closer to switching and computing silicon.

According to SemiconductorInsight, the Global Co-Packaged Optics Market was valued at USD 1.45 billion in 2025 and is projected to reach USD 4.12 billion by 2034, growing at an anchor-derived CAGR of 12.3% during 2026–2034. North America was identified as the largest market in 2025, while Asia-Pacific is an important manufacturing and deployment ecosystem.

Why Is Co-Packaged Optics Becoming Important?

CPO integrates optical components close to high-performance switching or computing silicon. This approach can shorten electrical signal paths and help address power consumption and signal-integrity challenges associated with moving large amounts of data.

CPO is particularly relevant to high-bandwidth data-center networks where switches must support communication between servers, accelerators and other infrastructure components.

Its commercial adoption depends on manufacturing yield, optical alignment, thermal management, fiber attachment and long-term serviceability.

AI Data Centers Drive Demand for Optical Interconnects

AI training and inference systems require rapid data exchange across large clusters of accelerators. As network bandwidth increases, the energy and engineering costs of moving data between components become increasingly important.

Optical interconnects can support high-speed communication over distances where electrical links become less attractive. CPO moves optical conversion closer to the switching silicon, creating opportunities to optimize bandwidth density and power efficiency.

Electrical and Photonic Integration Architectures

The report segments CPO into electrical co-packaged optics and photonic integrated co-packaged optics.

These approaches represent different integration strategies for combining electrical and optical functions. System designers must evaluate optical performance, packaging complexity, laser placement, manufacturing yield and maintenance requirements.

Data-Center Interconnect Is a Key Application

Data-center interconnect is a major application area because AI clusters and hyperscale infrastructure require increasing aggregate network capacity.

Telecom transport and high-performance computing provide additional opportunities. However, deployment depends on interoperability, system-level reliability and the ability to maintain optical performance in production environments.

Market Challenges

CPO introduces challenges associated with thermal design, optical alignment, manufacturing processes and repairability. Integrating optical components close to expensive switching silicon can complicate field maintenance and replacement.

Standardization and ecosystem maturity will influence how quickly customers adopt the technology at scale.
