TL;DREoptolink, a Chinese maker of high-speed optical transceivers, has filed for a secondary Hong Kong listing that could raise up to $5bn, above the $3bn floated in April. The angle: it is the AI boom’s unglamorous “picks and shovels” winner, its 800G/1.6T optical modules wire hyperscaler data centres, and customers include Google, Microsoft and Amazon. 2025 revenue was ~$3.7bn with net profit up 236% to ~$1.4bn. The piece notes the US-China interdependence (American AI runs on Chinese optics) and the capex-thesis risk it shares.
While attention fixes on Nvidia and the AI models, the companies quietly wiring the data centres together are booming. Eoptolink, a Chinese maker of high-speed optical transceivers, has filed for a Hong Kong listing that could raise up to $5bn, Bloomberg reports.
The plan is a secondary listing on top of its existing Shenzhen shares. It could raise $4bn to $5bn, well above the $3bn floated in April, a sign investor demand ran hotter than expected.
What Eoptolink makes
Its products are the unglamorous plumbing of AI. Optical transceivers convert electrical signals into light and back, moving data between servers and chips at enormous speed.
