Co-Packaged Optics Thermal Management Systems Market to Reach USD 2,381.9 Million by 2036 at 13.3% CAGR; France Grows at 13.4%, Germany at 13.1%

The Co-Packaged Optics Thermal Management Systems Market is projected to expand from USD 683.3 million in 2026 to USD 2,381.9 million by 2036, registering a 13.3% CAGR during the 2026 to 2036 forecast period. Demand is increasing as AI fabrics place optical engines closer to high-power switch silicon, concentrating heat within smaller packages.

Higher switch throughput is making thermal management an earlier design consideration. Broadcom's May 2025 third-generation CPO announcement moved to 200G per lane and documented changes involving thermal design, handling and fiber routing. These developments connect CPO qualification more closely with liquid-cooling infrastructure before rack layouts are finalized.

Data center power requirements are also influencing cooling decisions. Lawrence Berkeley National Laboratory estimated in June 2026 that USA data centers could consume 11.8% of national electricity by 2030. Higher site loads increase the need for dedicated cooling infrastructure and local liquid loops, particularly where dense AI networking equipment is deployed.

Global Segment Leaders

800G - 38.0%: Mature switch availability and established maintenance procedures support its position between 400G networks and newer higher-speed architectures.
Pluggable Optics - 32.0%: Modular optical replacement helps limit service disruption and keeps fault-isolation procedures familiar during fleet maintenance.
Inter-rack / Scale-out - 36.0%: High-port-count connections between racks repeat thermal requirements across leaf and spine switching nodes.
Hyperscale AI Data Centers - 48.0%: Repeated high-density deployments and centralized infrastructure qualification support demand from hyperscale operators.
The report does not provide a percentage share for the leading segment within every regional category, so no unsupported regional share has been added.

Analyst Perspective

FMI Principal Consultant Sudip Saha said, "Co-packaged optics makes thermal selection part of switch qualification because coolant interfaces affect optical alignment and field access. Programs reach fleet deployment faster once cooling control and replacement procedures are proven on the exact switch platform."

Country-Level Performance

South Korea | 14.8% CAGR: Government-backed AI compute programs are increasing requirements for additional GPU capacity, network infrastructure and supporting cooling systems.
UAE | 14.4% CAGR: Large greenfield AI and data center projects allow liquid-loop capacity, cooling redundancy and service access to be incorporated before compute halls become operational.
Japan | 14.1% CAGR: AI compute investment and demand for compact infrastructure are supporting adoption of thermal systems that preserve service access in space-constrained facilities.
USA | 13.8% CAGR: Hyperscale AI clusters are driving investment in liquid cooling alongside electrical and network infrastructure upgrades.
France | 13.4% CAGR: Additional candidate data-center sites and accelerated grid connections are supporting a broader pipeline for AI infrastructure development.
Germany | 13.1% CAGR: Data-center efficiency requirements and retrofit planning are influencing demand for liquid-cooling systems capable of integrating facility-level energy controls.
Regional Context

The six country forecasts range from 14.8% CAGR in South Korea to 13.1% in Germany. South Korea, the UAE and Japan record growth rates above 14.0%, supported by concentrated AI infrastructure investment, greenfield development and advanced compute requirements. The USA, France and Germany record growth rates between 13.1% and 13.8%, with infrastructure readiness, efficiency requirements and retrofit conditions influencing deployment schedules.

The full report covers North America, Latin America, Europe, East Asia, South Asia and Pacific, and the Middle East and Africa, with 20+ countries included in the complete report.

Competitive Landscape

The companies profiled in the co-packaged optics thermal management systems market include Eaton, Broadcom, nVent, Coherent, Vertiv, Schneider Electric, Ecolab, and ZutaCore. Competition spans liquid-cooling infrastructure, chip-level thermal systems, controls, CPO switching platforms and photonics technologies.

Eaton, nVent, Vertiv and Schneider Electric provide liquid distribution, cooling hardware and infrastructure solutions. Ecolab and ZutaCore address chip-level and advanced cooling requirements. Broadcom contributes CPO switching platforms, while Coherent supplies photonic technologies that influence optical-engine thermal and service considerations.

Recent developments include Schneider Electric's September 2025 introduction of a liquid-cooling portfolio covering CDUs, cold plates, chillers, software and field services. In August 2025, ZutaCore introduced a 240-kW two-phase sidecar designed to support waterless direct-to-chip cooling alongside existing air-cooled infrastructure. Vertiv also expanded its CoolChip CDU family in EMEA in June 2025 with models ranging from 70 kW to 600 kW for direct-to-chip AI and HPC applications.

The report identifies higher AI switch density as a key driver because thermal loads are increasingly concentrated inside network platforms. CPO qualification requirements remain a restraint because thermal, optical and mechanical interfaces require platform-specific validation. Standardized CDUs, manifolds and controls represent an opportunity as operators seek reusable liquid infrastructure across successive platform generations.
