Origin
Cui Genliang is from Qidu, Wujiang, Jiangsu. A former communications soldier, he took over a township agricultural machinery factory with about 1.2 million RMB in debt after retiring. Around 1991, judging that communications network construction was about to explode, he decided to pivot from cables to optical communications, becoming a classic case of starting out with 'two thin threads.' At the time, China's core optical fiber and cable technology—the optical fiber preform—was monopolized by foreign enterprises like Corning; his obsession was to master this most critical upstream link.
Milestones
1991
Taking Over a Crisis Failure
In 1991, Cui Genliang took over a near-bankrupt township agricultural machinery factory in Wujiang with about 1.2 million RMB in book debt, where workers' wages were difficult to sustain. His initial business attempts were not smooth, and clients rejected him to his face when pitching the market; internally, this period is remembered as the darkest starting point of entrepreneurship.
1993
Establishing a Foothold in Cables Turning Point
Cui Genliang led a team to switch production to cables and quickly secured orders, subsequently introducing optical fiber and cable production lines through a joint venture with a foreign company. The Wujiang factory scaled from a small plant with an annual output value of several million RMB to over 100 million RMB, validating the deterministic demand of the telecom infrastructure industry for the first time and accumulating funds for later self-research. This phase lasted from 1993 to 1999.
2003
Entering the Capital Markets Turning Point
Hengtong Optic-Electric was listed on the Shanghai Stock Exchange in 2003, with raised funds primarily directed toward optical cable expansion and upstream technological breakthroughs. Listing provided the township enterprise with a continuous financing channel, and Cui Genliang clearly designated the optical fiber preform as the next fortress that had to be conquered.
2006
Tackling Preforms PMF
Hengtong invested hundreds of millions of RMB to organize a team to tackle optical fiber preforms. Early experiments failed repeatedly, scrapping a large volume of equipment. Around 2010, independent mass production of preforms was achieved, breaking the monopoly held by foreign companies like Corning on a link that accounts for about 70 percent of optical fiber costs, directly reshaping domestic optical fiber pricing power. This phase lasted from 2006 to 2010.
2015
Global M&A Expansion Growth
Hengtong built production facilities and acquired overseas cable companies in Southeast Asia, Africa, and Europe. Marine optoelectronics and submarine power cables became its second growth curve, pushing Hengtong Group's annual revenue past tens of billions of RMB. Cui Genliang proposed transforming Hengtong into a global optical communication and power transmission system solution provider. This phase lasted from 2015 to 2019.
2020
Industry Slump and Skepticism Failure
Domestic optical fiber and cable centralized procurement prices plummeted amid industry overcapacity. Combined with heavy investments in marine engineering, Hengtong Optic-Electric faced rising accounts receivable and debt pressure. Around 2021, it also encountered market skepticism regarding its related-party structure, its stock price remained sluggish for a long time, and preform profits were swallowed by price wars. This phase lasted from 2020 to 2023.
2025
AI Computing Dividends Growth
AI data center construction ignited demand for optical fibers and high-speed optical modules. In the first half of 2026, Hengtong Optic-Electric's market value surged by about 130 billion RMB, pushing its estimated market valuation range close to 200 billion RMB. The Hengtong family of companies planned another IPO, and Cui Genliang and his son welcomed a second spring. This phase lasted from 2025 to 2026.
Turning Points
- In 1991, preferring to shoulder 1.2 million RMB in debt rather than return to a government office, he decided to bet his life on a township manufacturing enterprise.
- In 1993, after listing and raising capital, he did not rest in the comfort zone of cables, pouring funds into the most difficult preform R&D.
- In 2010, independent mass production of preforms was achieved, transforming the company from an import follower to a direct challenger against Corning.
- In 2026, when AI computing demand exploded, the veteran optical fiber manufacturer transformed into a leading concept stock in computing infrastructure.
Failures & Pitfalls
- In the early days of taking over the machinery factory, products were hard to sell, facing customer rejections was routine, and the debt-to-asset ratio once caused banks to refuse loan renewals.
- Early optical fiber ventures relied on joint ventures to buy technology; foreign companies choked core equipment, and the lion's share of profits was taken by the upstream.
- The early stages of preform R&D saw repeated experimental failures, and tens of thousands of fiber-kilometer production line equipment were scrapped, burning through massive amounts of capital.
- After 2019, industry overcapacity halved prices, and the market briefly questioned Hengtong's high-debt expansion model.
关键成功要素
- Tackling the toughest upstream preform segment to keep cost and pricing power in its own hands.
- Leveraging township enterprise restructuring and public listing financing to complete the identity leap from a grassroots outfit to a capital platform.
- Building a second growth curve with submarine optical cables and power transmission to hedge against optical fiber cyclical fluctuations.
- Establishing global factories and executing M&As to export Chinese manufacturing capabilities to Asian, African, and European markets.
Lessons
- Conquering the industry's most critical 1 percent choke point yields far greater value than doing 100 percent of the assembly.
- The R&D investment cycle for heavy-asset projects spans decades; cash flow management is more vital to survival than technical ideals.
- Poor book performance during industry downcycles does not equate to failure; accumulated capacity and technology will outlast the downturn for the next wave of demand.
- Staying in the game as a founder over the long term matters more than any short-term trend judgment.

Competitors / Peers
Hengtong Optic-Electric's competitors in the optical fiber and cable race include YOFC, FiberHome, Hengtong's peers like ZTT, and global titan Corning. YOFC has the deepest technical accumulation in preforms, ZTT is strong in the submarine cable business, FiberHome relies on central enterprise resources to undertake operator centralized procurement, and Corning has long held a monopoly on high-end preform patents. Hengtong's multi-point focus is the integration of preform, fiber, and cable plus marine engineering, relying on an entire industrial chain and global layout to protect its market share during price wars. During the upswing in AI demand in 2026, peers generally surged, with the core of competition remaining preform self-sufficiency.
