What kind of company is Sanshiyuan Technology? How did it manage to secure nearly 100 million yuan in funding? What are its core strengths and background?

Established in 2015, Sanshiyuan Technology stands as a leading company in the domestic market for key passive devices like circulators and is among the firms with the most rapid progress in commercializing optical circuit switches.

Founder Chen Xiangyang holds a Master's degree in Optics from the Physics Department of Harbin Institute of Technology. With two decades of experience in product development within the optical communication industry, he previously served as the sales head for Oplink China, steering his team to achieve annual sales figures in the hundreds of millions of yuan.

The company's core team members all boast 20 years of experience in product development in the optical communication sector and hail from internationally renowned enterprises. Moreover, the team has nearly 20 years of collective experience in MEMS technology, with a specific focus on MEMS for the past six years. Four years ago, they embarked on technical preparations, research, and product development related to optical circuit switches (OCS). Through process enhancements, they have successfully addressed the stability challenges of MEMS OCS, enabling the mass supply of 300×300 port configurations.

Sanshiyuan Technology's main product lineup includes optical circuit switches (OCS), circulators, high-power and polarization-maintaining laser devices, multi-core fiber fan-in/fan-out devices (MCF FIFO), and optical amplifier integration and array devices. These products find extensive applications in data centers, LiDAR systems, industrial lasers, 5G base stations, surveying and mapping, backbone network relays, coherent transmission, optical testing, optical medical devices, and other fields.

Among these offerings, the circulator commands a leading global market share, while the optical circuit switch (OCS) is at the forefront in China, with commercial deliveries already underway. This year, the company will introduce OCS models featuring over 512 ports. Currently, several products from Sanshiyuan Technology have penetrated the supply chains of leading global industry clients. The company has witnessed a 10-fold increase in performance over the past five years, boasting a compound annual growth rate (CAGR) exceeding 60%.

Leveraging its accumulated strengths, Sanshiyuan Technology has earned accolades such as the national-level "Specialized, Refined, and New Little Giant," Innovative SME, and Zhuhai City Unicorn Seed Enterprise. It has also been recognized in the 2022 Optics Startup Financing Rankings and the 2024 Greater Bay Area High-Growth Enterprises Top 100 List.

Looking to the future, Sanshiyuan Technology plans to continue its expansion trajectory, with anticipated moves to establish a branch in Shanghai, set up an overseas company in Singapore, and establish a production base in Southeast Asia to attract high-end and international talent.
