TrendForce: The global AI optical transceiver module market size is estimated to reach US$26 billion in 2026

According to the latest research from TrendForce, the global AI-specific optical transceiver module market has entered a stage of rapid growth. The market size is estimated to expand from US$16.5 billion in 2025 to US$26 billion in 2026, an annual increase of more than 57%. The strong growth not only comes from specification upgrades, but also reflects that the overall optical communications supply chain is facing structural restructuring due to the accelerated construction of AI data centers.

AI data centers continue to expand, with transmission rates above 800G and demand for optical transceiver modules for AI Server cluster interconnection increasing significantly. The traffic of ultra-large data centers in North America has maintained an annual growth rate of more than 30% for a long time, prompting cloud giants such as Google, Microsoft and Meta to increase their deployment of GPUs and AI servers, further driving the procurement demand for high-speed optical connections. However, supply chain pressures have emerged simultaneously.

TrendForce pointed out that the expansion of optical transceiver module production currently faces several major bottlenecks: First, key optoelectronic chips such as EML (electroabsorption modulated laser) and CW-LD (continuous wave laser) are in tight supply due to production capacity allocation issues. High-precision process capabilities such as optical alignment are also factors limiting production capacity expansion. In addition, power consumption and heat dissipation issues still affect the overall system design and introduction rhythm.

In order to reduce supply risks, upstream suppliers and major system manufacturers, led by NVIDIA, have adjusted their procurement models and begun to introduce strategic long-term contract mechanisms to lock in key materials and gradually reduce their reliance on spot purchases. At the same time, the technology roadmap is also accelerating towards low-power linear pluggable optics (LPO) and silicon photonics integration solutions, hoping to replace the traditional high-power DSP (digital signal processor) architecture to alleviate power consumption and heat dissipation pressure.

According to TrendForce Consulting’s analysis, the growth momentum of the AI ​​optical transceiver module market has been upgraded from a single product specification to a parallel development of the three main axes of “market scale expansion”, “technology generation switching” and “application scenario extension”. As the 1.6T generation gradually enters mass production, and the demand for edge computing and regional data center interconnection (DCI) takes shape, the 800G and 1.6T ZR/ZR+ coherent optical module markets will also expand simultaneously.
