Optical Interconnect Market Report 2025

The optical interconnect market size has grown rapidly in recent years. It will grow from $12.23 billion in 2024 to $13.69 billion in 2025 at a compound annual growth rate (CAGR) of 11.9%. The growth during the historic period can be attributed to rising demand for cloud computing, increasing bandwidth requirements, expansion of 5G networks, growth of data centers, and higher demand for internet services.

The optical interconnect market size is expected to see rapid growth in the next few years. It will grow to $21.15 billion in 2029 at a compound annual growth rate (CAGR) of 11.5%. The growth during the forecast period is expected to result from the expansion of quantum computing networks, growth of edge computing infrastructure, rising hyperscale cloud investments, increasing demand for energy-efficient solutions, and higher network traffic from both private and government sectors. Key trends in this period include advancements in silicon photonics, development of co-packaged optics, innovations in 800G/1.6T transceivers, growth of AI-driven data centers, and progress in quantum communication applications.

The rapid expansion of 5G networks is expected to drive growth in the optical interconnect market. 5G networks provide faster data speeds, lower latency, and support for massive device connectivity and advanced applications such as IoT and smart cities. Their expansion is accelerating to accommodate the growing number of connected devices in the IoT ecosystem, enabling seamless communication, real-time data exchange, and smarter automation across industries. Optical interconnects support 5G networks by providing fast, low-latency, and reliable data links between network elements, ensuring efficient connectivity for high-density networks and real-time services. For example, according to 5G Americas, North America is expected to reach 289 million 5G connections by the end of 2024, a 67% increase from 196 million connections at the end of 2023. The rapid growth of 5G networks is therefore fueling demand for optical interconnect solutions.

Companies in the optical interconnect market are developing optical interconnect chiplets to enhance data transfer speeds, reduce latency, and improve energy efficiency in high-performance computing and data center applications. Optical interconnect chiplets are compact semiconductor modules that use light signals to transfer data between or within chips, increasing bandwidth, reducing latency, and lowering power consumption. In April 2025, Ayar Labs launched the TeraPHY optical I/O chiplet, the world’s first Universal Chiplet Interconnect Express (UCIe) optical chiplet. It integrates silicon photonics with CMOS manufacturing, delivering 8 Tbps bandwidth using a 16-wavelength SuperNova light source. Designed for AI scale-up architectures, it addresses data bottlenecks by enabling ultra-high-speed optical interconnects between chiplets while reducing latency and power usage. The chiplet supports the UCIe open standard, promoting compatibility and a cost-effective ecosystem for optical technologies.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid rise in U.S. tariffs and the subsequent trade frictions in spring 2025 are having a major impact on the electrical and electronics sector, with semiconductors, display panels, and rare-earth metals (essential for batteries and motors) subject to steep duties. Consumer electronics brands face profit erosion, as competitive markets limit their ability to pass costs to buyers. Industrial electronics manufacturers, meanwhile, grapple with delayed projects due to shortages of tariff-impacted components like printed circuit boards. Companies are responding by relocating assembly to tariff-exempt countries, increasing inventory buffers, and redesigning products to reduce dependency on restricted materials.

Optical interconnect is a communication technology that transmits data using light signals through optical fibers or photonic devices instead of traditional electrical wiring. By using photons rather than electrons, it enables higher data transfer speeds, increased bandwidth, and reduced signal degradation, making it essential for high-performance computing, data centers, and advanced telecommunications networks.

The main product types in optical interconnect include cable assemblies, connectors, optical transceivers, silicon photonics, optical engines, photonic integrated circuit-based interconnects, free-space optics, fibers, and waveguides. Cable assemblies are prefabricated bundles of cables with attached connectors, designed to transmit signals efficiently and reliably. They include single-mode fiber (SMF) and multimode fiber (MMF) and are applied across metro and long-haul networks, board or rack-level, and chip or board-level interconnects. Technologies used include optical waveguides, optical fibers, vertical-cavity surface-emitting lasers (VCSELs), optical transceivers, and optical switches, supporting applications in data centers, telecommunications, high-performance computing, consumer electronics, and automotive.
