Nuowanxin Microelectronics (registered name: Hangzhou Nuowanxin Microelectronics Technology Co., Ltd.) was established in March 2025, headquartered in Xiaoshan, Hangzhou, with subsidiaries in Chengdu, Zhuhai, Shenzhen, and Shanghai. It focuses on dedicated electric chips for high-speed optoelectronic interconnection in AI data centers. With self-developed SerDes as the technical foundation, its products cover two lines: optical interconnection (CDR, oDSP) and electrical interconnection (AEC, ACC), targeting high-speed optical modules and active cable scenarios. Its main strategy is 'optical and copper advancing together' for domestic full-stack supply. The founder, Wen Rui, has over 15 years of experience in the high-speed optoelectronic interconnection chip industry. The company completed a pre-seed round of nearly 100 million yuan led by Haiyetiankong Venture Capital and followed by Honghui Fund within 8 months of its establishment. On July 30, 2026, it again received over 100 million yuan in pre-A round funding from Jiahe Asset, Shenglan Co., and Chengdu High-tech Venture Capital.

Founded in April 2019 and headquartered in Haining, Zhejiang, Guoke Guangxin (CSPC) is a national high-tech enterprise focused on silicon nitride (SiN) photonic chip technology, covering materials, chip design, packaging, optoelectronic devices and system integration. Its products include datacom silicon photonic chips (400G/800G/1.6T), 3.2T/6.4T NPO/CPO and OIO chiplets, tunable narrow-linewidth coherent light sources, and FMCW/dToF solid-state lidar, serving AI clusters, high-speed data centers, fiber sensing and OCT applications. It acquired Dutch coherent laser company CHILAS in 2023; the team numbers 190+ with over 60% in R&D and 250+ patents.

Haiguang Xinzheng is a provider of silicon photonics chips and high-speed optoelectronic interconnect products, including optical modules, active optical cables (AOC), and high-speed active electrical cables. Its products are deployed in AI data centers to support high-speed, high-density data transmission. The company is among the few globally with both silicon photonics chip design capabilities and the ability to develop and mass-produce silicon photonic optical modules.

Ayar Labs, founded in 2015 in San Jose, California, develops optical interconnect technology that uses light to transmit data between computer chips to address data transfer bottlenecks in AI systems.

MangoBoost, founded in 2016 in Seattle, USA and Seoul, South Korea, develops DPUs that help data centers reduce energy consumption and optimize performance. The DPU market is becoming increasingly competitive, with many companies offering similar technology, including Microsoft FPGA smart NICs and Amazon Nitro.
