GlobalFoundries reports robust demand for optical modules in China, driven by rapid data center expansion and increased need for high-speed data transmission using photonics technology.
- Chinese firms produce nearly two-thirds of global optical transceivers.
- GlobalFoundries acquired Advanced Micro Foundry, becoming the largest silicon photonics foundry.
- US regulators plan telecom restrictions that may affect Chinese optical module supply.
What happened
GlobalFoundries, a US semiconductor manufacturer, announced increased demand for optical modules in China. These modules play a crucial role in data centers by converting electronic data into optical signals, enabling faster data transmission between servers. This surge is attributed to the rapid construction of data centers across China.
To capitalize on this demand, GlobalFoundries is expanding its presence in China and broadening its photonics capabilities, including its 2025 acquisition of Singapore-based Advanced Micro Foundry. This purchase has positioned the company as the largest pure-play silicon photonics foundry globally, enhancing its ability to supply advanced chips needed for optical data transfer.
Why it matters
Chinese companies dominate the global optical transceiver market, producing roughly two-thirds of these components. As data centers proliferate, the demand for optical modules continues to grow, highlighting the strategic importance of photonics technology in modern computing infrastructure.
GlobalFoundries’ investments in photonics and local manufacturing partnerships, such as the agreement to produce automotive chips through a Chinese foundry, underscore the critical role of localized production amid complex geopolitical dynamics. Meanwhile, the US Federal Communications Commission is drafting potential bans on Chinese optics products, which could disrupt supply chains and increase costs for US cloud service providers.
What to watch next
Industry observers should watch for the impact of US regulatory measures on the availability and pricing of Chinese optical modules. Restrictions imposed by the FCC could shift sourcing strategies for major cloud firms like Amazon and Microsoft, potentially increasing reliance on GlobalFoundries’ expanded photonics capacity.
Additionally, GlobalFoundries’ announced capacity expansions, driven by growing AI workloads in data centers, will be crucial to meet future demand. The company's continued integration of photonics technology and partnerships in the Asia-Pacific region will shape competitive dynamics in the optical module market.
