About Vulcantech

Poncan Semiconductor Co. Ltd. is a fabless design startup that provides optical interconnection foundations and semiconductor solutions. Founded in 2019 by Chairman Mr. Chunchao Li and co-founded by semiconductor executives from Marvell, Realtek, and Qualcomm, the company is headquartered in Hangzhou, China, with additional offices in Shanghai and Shenzhen. The firm is backed by venture capital and raised over CNY 100 million in a Series B funding round in June 2026. The company's core technology is the Time-Sensitive Passive Optical Network (TS-PON), formerly known as PonCAN. This industrial control network technology is based on optical transmission, providing a communication platform for robotics and industrial control. The TS-PON architecture delivers high bandwidth, low latency, and high reliability for edge artificial intelligence (AI) applications. The business generates revenue by designing and selling software-defined network systems-on-chips (SoCs), optical communication chips, and system modules to original equipment manufacturers (OEMs) and enterprise clients. Poncan's product portfolio includes a range of highly integrated, single-chip SoCs designed for various applications. Products like the VN180x and VN1802 are Passive Optical Network (PON) Optical Line Terminal (OLT) MACs, which provide cost-effective solutions for Fiber-to-the-Home (FTTH) and Fiber-to-the-Room (FTTR) applications. The VN1108 is a high-performance Optical Network Unit (ONU) SoC supporting XGSPON/XGPON standards. These solutions are engineered to support high-speed applications such as AR, VR, and 8K video, while offering lower power consumption compared to FPGA-based alternatives. The company plans to use its latest funding to advance the mass production of its automotive time-sensitive passive optical network chip and accelerate R&D for next-generation products targeting AI data centers and intelligent optical neural networks.
