About Triple-Stone

The Leader of Fiber-Optic Devices

Founded in 2015 and headquartered in Zhuhai, China, Triple-Stone Technology is a leading manufacturer of miniaturized, integrated fiber-optic devices. Our team numbers more than 1,500 people, including a core group with over 20 years of industry experience.

Our portfolio covers the optical link end to end, across four major lines: OCS, MEMS switches & circulators; high-density connectivity; coherent & optical amplifier components; and active access modules. Our products are widely deployed in AI data centers, telecommunications, industrial lasers, and other emerging fields.

We run R&D centers in Singapore, Shanghai, and Zhuhai, and operate manufacturing sites in Zhuhai, Shenzhen, Hunan, and Bangkok — nearly 57,000 m² of facilities including Class 1,000 and Class 10,000 cleanrooms — serving over 500 customers worldwide.

Driven by innovation and quality, Triple-Stone is ISO 9001 certified, and all products are qualified to Telcordia standards (GR-1221/1073/468/63) and comply with RoHS/REACH and conflict-minerals requirements.
