All-optical data center switch market seen topping $6.32 billion by 2030

The all-optical data center switch market is projected to jump from $1.69 billion in 2025 to $6.32 billion by 2030, driven by AI workloads, cloud growth and demand for faster, more energy-efficient networking. North America led the market in 2025, while Asia-Pacific is expected to grow the fastest.

Why it matters: - The all-optical data center switch market is moving toward a much larger role in data center networking as operators look for lower latency, higher bandwidth and better energy efficiency. - Rising AI usage, hyperscale infrastructure and 400 Gigabit-per-second-plus connectivity needs are pushing demand for optical switching architectures.

What happened: - The Business Research Company said the global all-optical data center switch market will rise from $1.69 billion in 2025 to $2.2 billion in 2026. - The market is forecast to reach $6.32 billion by 2030, which would imply a 30.2% CAGR. - The report is titled The All-Optical Data Center Switch Global Market Report 2026 – Market Size, Trends, And Forecast 2026-2035. - The company made the report available with a free sample and the full report.

The details: - The market grew on the back of escalating data center network traffic, broader cloud computing adoption, faster data transmission needs, hyperscale data center expansion and higher bandwidth requirements. - The technology routes data entirely through optical signals and avoids optical-to-electrical-to-optical conversion during transmission. - The design supports very low latency, high bandwidth and improved energy efficiency. - The report says those traits make the switches suitable for AI workloads, cloud computing and hyperscale data center networks. - By 2030, growth drivers are expected to include more AI workloads, wider use of 400 Gbps and faster links, more high-performance computing clusters, energy-efficient networking goals and expansion of edge data centers. - Emerging trends cited in the report include silicon photonic switching architectures, ultra-low-latency optical switching, high-bandwidth optical switching systems, integrated photonic circuit switches and scalable optical switching solutions. - In June 2024, Ericsson said 5G networks are expected to account for 34% of total mobile data traffic by the end of 2024, up from 25% at the end of 2023.

Between the lines: - The forecast points to a broader data center shift away from conversion-heavy networking toward optical systems that can handle AI-era workloads more efficiently. - The emphasis on energy efficiency suggests customers are looking beyond speed alone and weighing power use as traffic and compute loads climb. - The report’s trend list indicates the market is still early, with switching architectures and photonic integration likely competing to define the next wave of products.

What's next: - North America was the largest regional market in 2025. - Asia-Pacific is expected to be the fastest-growing region over the forecast period. - The report also covers South East Asia, Western Europe, Eastern Europe, South America, the Middle East and Africa. - The Business Research Company said its 2026 reports include market attractiveness scoring, TAM analysis, company scoring matrix graphics, Excel dashboards, market hotspot infographics and updated graphics and tables.

The bottom line: - All-optical data center switches are moving from niche infrastructure to a fast-growing market tied directly to AI, cloud and next-generation data traffic.
