InnoLight Brand Guidelines: The Suzhou Transceiver Maker Inside Zhongji InnoLight

A transceiver start-up and a winding-machine maker.

InnoLight began in 2008 as InnoLight Technology (Suzhou), a maker of optical transceivers — the small plug-in modules that turn electrical signals into light and back again so that servers and switches can talk over optical fibre. English Wikipedia dates the founding to April 2008, and Chinese Wikipedia credits it to Liu Sheng, a scientist who had returned to China from abroad; the company lists Dr. Sheng Liu as its chief executive today. InnoLight’s own English site adds a wrinkle: it calls its American arm, InnoLight Technology USA, “the company’s origin,” and gives it research, marketing and customer-service roles.

The start-up grew with cloud computing. English Wikipedia says its early investors included Google Capital, Lightspeed Venture Partners and Oriza Holdings, and that they backed it because of its importance to data centres. The company’s own timeline says that in 2012 InnoLight launched its 40G QSFP+ transceivers, which it describes as the foundation of its later growth in data-centre networking.

The listed half of today’s company has a very different history. Shandong Zhongji Electrical Equipment, from Longkou in Shandong province, made machinery: English Wikipedia says it was one of the first Chinese makers of computer-controlled machines for winding electric motors, and that it listed on the Shenzhen Stock Exchange in April 2012. Its founding date varies by source — Wikipedia gives 1987, while the company’s own timeline begins with a Longkou electrical-machinery company in 2005.

From Zhongji to Zhongji InnoLight.

The two businesses came together through a reverse route: the machinery maker bought the transceiver maker. Chinese Wikipedia says Zhongji acquired Suzhou InnoLight in 2016 and took the name Zhongji InnoLight in September 2017; English Wikipedia dates the acquisition to 2017 and says the listed company kept its stock ticker while the machinery business was spun out as a separate subsidiary. The company’s own timeline records the restructuring and renaming in 2017. So InnoLight reached the Shenzhen market inside an existing listed company rather than through an offering of its own.

Growth by acquisition followed. English Wikipedia says Zhongji InnoLight bought Chengdu Tsuhan Science & Technology, a maker of optical components and transceivers, in February 2020, and Chongqing Junge Electronic Technology in July 2023. Tsuhan still appears as a sister site on InnoLight’s website, alongside Tongling InnoLight.

The product story is told through speeds. On its corporate timeline the company claims a series of industry firsts: a 400G QSFP-DD FR4 transceiver in 2018, the first 800G pluggable OSFP and QSFP-DD800 modules in 2020, and the first 1.6T transceiver in 2023; these are the company’s own claims. Its English site groups the range into three solutions — AI and data-centre networking, mobile networking for front-haul, mid-haul and back-haul, and metro and long-haul networks built on coherent detection — and in March 2024 it announced work with Marvell on 800G ZR/ZR+ modules for links between data centres.

The AI boom changed its scale. In September 2025, English Wikipedia says, its shares were among the top performers on China’s onshore benchmark as data centres ordered transceivers to link thousands of GPUs in AI clusters. AFP reported in July 2026 that it supplies customers including Google, Nvidia and Huawei.

Design and documentation.

Photonics companies sell things most people never see. Their lasers sit inside machine tools, their transceivers inside data-centre racks, and their detectors inside instruments, telescopes and physics experiments. So the way they present themselves leans on a small set of images that make light visible: a laser beam crossing a dark optical table, the glowing end of a fibre, a row of pluggable transceiver modules lined up for a switch, or a photomultiplier tube and a sensor chip photographed under studio light against black.

The catalogue matters as much as the advertisement. Many makers of optics and components publish long product catalogues of lenses, mirrors, mounts, filters, tubes and diodes, each part with a drawing, a part number and a page of specifications. That catalogue habit gives much of the sector a shared look: clean technical photography, plenty of white or black space, careful diagrams and an engineering sans or a restrained serif, with colour used sparingly, often for a single accent.

The trade shows are where the industry gathers in person. Photonics West, LASER World of PHOTONICS and OFC, the optical fibre communication conference, are among the events where companies show new lasers, modules and detectors, and their stands and press releases often borrow the same visual language of beams, fibres and glowing chips. Company histories also lean on science: makers of detectors and light sources often point to the research projects and observatories that have used their parts.

This guide sets out what can be checked about each brand — who founded it, who owns it, what it has bought or sold and what it makes — and marks clearly what rests only on the company’s own word. Pending deals are described as pending, with the date they were announced.

Two listings and a US blacklist.

InnoLight now makes its modules in several countries. Its English site says InnoLight Suzhou remains a research, engineering and production base; that a Singapore company set up in 2018 serves as the group’s international headquarters; that a high-volume plant in Thailand was established in 2019, which the corporate timeline says began operating in 2022; and that it also has a unit in Taiwan. Where a given module is made is not stated product by product.

Washington has taken a closer interest. In October 2025, English Wikipedia says, the US Department of Defense stated that Zhongji InnoLight merited inclusion on its list of Chinese military companies, and in June 2026 the department added it to that list. AFP reported in July 2026 that the company rejected the claim in its Hong Kong filing, saying it had “not engaged in any military-related businesses or activities,” and warned investors that the listing could bring further scrutiny. InnoLight’s English site carries a trade-compliance section with its compliance commitment and policy.

The group also gained a second market. China’s securities regulator and the Hong Kong exchange approved a Hong Kong listing in July 2026, The Star reported, and the shares began trading on 30 July 2026; RTHK reported that they fell on their first morning and that the sale was Hong Kong’s largest of the year and the city’s biggest since Alibaba’s secondary listing in 2019. The company now quotes two codes, 300308 in Shenzhen and 3308 in Hong Kong, and presents itself as Zhongji InnoLight on its investor site and as InnoLight on its product site.

The name itself splits in two. The Chinese name, 中际旭创, joins the first syllables of the old machinery company with Xuchuang, the Chinese name of the Suzhou start-up, while English-language customers mostly meet the short InnoLight brand, under the line “Innovation Lights Our Future.”

For a design guide, InnoLight shows how a component maker with a quiet, engineering-led brand can become a household name in financial news without changing how it presents itself. Compare Lumentum and Coherent, two more photonics makers in this series. For this guide we use a fibre navy, a signal teal and a pale mist with a sans, an unofficial interpretation; no product or logo is reproduced.
