Global Co-Packaged Optics and 1.6T Data Center Interconnect Market — Intelligence Report

The global co-packaged optics and 1.6T data center interconnect market is entering a decisive commercialization phase as cloud-scale operators, large digital infrastructure owners, and advanced compute environments push conventional pluggable optics toward thermal, power, and density limits. Nexvora Intelligence estimates the combined 2025 market at approximately US$•••–••• billion, with 1.6T optical modules and related interconnect systems representing the near-term revenue base while co-packaged optics remains concentrated in qualification programs, limited deployments, and platform-specific design wins.

Demand is being shaped by the transition from 400G and 800G network layers toward 1.6T links across spine-leaf fabrics, campus-scale data center interconnect, and high-radix switching environments. The economics of bandwidth growth are increasingly tied to watts per bit, faceplate density, thermal management, and signal integrity rather than headline port speed alone. As switch ASIC bandwidth advances beyond 51.2T toward 102.4T and higher-class platforms, optical integration is moving closer to the switching silicon, creating a structural opening for co-packaged optics after several cycles of industry experimentation.

Nexvora models the market expanding at an estimated 38–••% CAGR through 2032, reaching approximately US$•••–••• billion by the end of the forecast period. Growth will not be linear: the 2025–2027 window is expected to be led by 1.6T pluggable and near-pluggable optics, while 2028 onward is likely to see broader co-packaged optics adoption in selected hyperscale, high-performance compute, and bandwidth-dense switching environments. The market’s inflection point will depend on serviceability models, laser source architectures, ecosystem standardization, and procurement confidence in long-lifecycle optical-switch platforms.

The competitive landscape is consolidating around a small set of optical module suppliers, silicon photonics platforms, switch silicon vendors, advanced packaging specialists, and systems OEMs capable of addressing both optical performance and data center operating constraints. Differentiation is shifting from discrete module speed toward full-stack execution: thermal co-design, test yield, fiber management, manufacturing scale, reliability under dense operating conditions, and integration with switching and routing platforms.

Nexvora Intelligence developed this opening outlook using proprietary market modeling across optical interconnect demand, switching platform roadmaps, data center bandwidth growth, regional infrastructure expansion, and vendor commercialization readiness.

The model triangulates bottom-up shipment assumptions for 1.6T interconnect products with top-down capital expenditure patterns across hyperscale, colocation, telecom cloud, and high-performance compute environments.

Co-packaged optics adoption was modeled separately from 1.6T pluggable and near-pluggable interconnect revenue to reflect different commercialization timelines, qualification cycles, serviceability requirements, and platform dependencies.

All market sizes, growth rates, regional assessments, and share indications in this opening are Nexvora modeled estimates and should be interpreted as directional planning ranges rather than externally sourced reported figures.
