In the 1980s, during the early stages of China's reform and opening-up, the nation's communication infrastructure was severely underdeveloped, becoming a critical bottleneck constraining economic growth. At that time, the country planned the "Eight Vertical and Eight Horizontal" national primary optical cable trunk network project. However, the core material, optical fibre, was entirely dependent on imports, with high costs and supply controlled by foreign entities. Against this backdrop, breaking foreign technological monopolies and achieving domestic production of optical fibre became an urgent national strategic imperative.
A Twenty-Year Journey of Localization Yangtze Optical Fibre And Cable Joint Stock Limited Company was founded in the tenth year of China's reform and opening-up, coinciding with a period of酝酿 global transformation in information and communication technology. From its inception, its goal was clear: to introduce, digest, and assimilate the PCVD (Plasma Chemical Vapor Deposition) optical fibre preform technology from the Netherlands' Philips, aiming to achieve domestic production of optical fibres and cables. This path was arduous. In 1991, Yangtze Optical Fibre produced its first finished optical fibre; in October of the same year, it began cable production. A true turning point came in 1992 when the company commenced full-scale production of optical fibres and cables, exceeding its design targets that year by producing and selling 5,000 kilometres of cable and 60,000 kilometres of fibre. This not only signified that China finally possessed the capability for large-scale optical fibre production but also meant that China's domestic demand for optical fibre was从此 no longer reliant on imports. Throughout the 1990s, Yangtze Optical Fibre grew rapidly under a joint venture framework of "trading market for technology." By 1997, it had successfully mastered and achieved mass production of single-mode fibre technology, becoming the world's third company to master this technology (following Corning and Lucent in the U.S.). In 1999, it launched a series of new products, including skeleton ribbon cables and all-dielectric self-supporting cables, continually enriching its product line. Overall, the challenges of this phase laid the industrial groundwork for Yangtze Optical Fibre's subsequent technological self-innovation. Entering the 21st century, China's telecommunications industry experienced explosive growth. The proliferation of landlines, mobile communications, and the internet began generating massive demand for fibre-optic networks. Yangtze Optical Fibre clearly realized that merely being a technology importer was unsustainable; it had to master the most upstream and technologically valuable part of the fibre-optic industry chain—the optical fibre preform. The optical fibre preform is the base material for drawing optical fibre, involving极高 technical difficulty and offering the highest profit margins, accounting for approximately 70% of the entire industry chain's profits (the profit distribution among preform, fibre, and cable is roughly 7:2:1). Before 2000, China was almost entirely dependent on imports for optical fibre preforms. Consequently, Yangtze Optical Fibre elevated independent R&D to a strategic corporate level, establishing a dedicated R&D department. After several years of technological攻关, between 2002 and 2005, the company successfully developed and mass-produced optical fibre preforms independently, breaking China's long-standing import dependency for this product in one fell swoop. Looking back, the core of this industrial model lies in the fact that Yangtze Optical Fibre从此 mastered the complete production capability, from manufacturing upstream optical fibre preforms, to drawing midstream optical fibres, and finally to cabling downstream optical cables. Based on this achievement, in 2005, Yangtze Optical Fibre's research on PCVD process preparation of non-zero dispersion shifted single-mode fibre and its large-scale production technology won the National Science and Technology Progress Award (Second Class). This was the highest scientific and technological award received by a Chinese通信 enterprise at the time, also marking the firm recognition of its technological capabilities at the national level. In 2011, Yangtze Optical Fibre established the "State Key Laboratory of Optical Fibre and Cable Manufacturing Technology," the only national-level enterprise key laboratory in China's optical fibre and cable industry. The establishment of this laboratory marked Yangtze Optical Fibre's transition towards冲刺 industry technical standards and leadership. In the same year, the company developed "Full-Band Low-Loss Single-Mode Fibre" and put it into commercial production. By 2013, Yangtze Optical Fibre had grown into the world's largest supplier of optical fibre preforms and the second-largest supplier of optical fibres and cables globally. This laid a massive capacity foundation for its subsequent capitalization and global expansion. 至此, through relentless effort, Yangtze Optical Fibre successively mastered the three major mainstream preform manufacturing processes: PCVD (Plasma Chemical Vapor Deposition), OVD (Outside Vapor Deposition), and VAD (Vapor-phase Axial Deposition). This vertical integration model brought unparalleled competitive advantages. First, in-house preform production significantly reduced raw material costs and ensured product quality stability and consistency from the source. Second, in the face of global supply chain fluctuations, Yangtze Optical Fibre could guarantee a stable supply of core raw materials, thus possessing极强的 risk resilience (e.g., although operating revenue declined in 2023, the gross profit margin for its fibre and preform business反而 increased by nearly 6 percentage points to 53%).
From Domestic Dependence to Global Layout In 2014, Yangtze Optical Fibre and Cable Joint Stock Limited Company was listed on the Main Board of the Hong Kong Stock Exchange, marking a critical milestone in its development history. The company formally entered international capital markets, and the funds raised laid the groundwork for subsequent capacity expansion, technological攻坚, and overseas acquisitions. Notably, almost同步 with the listing, the curtain was raised on a large-scale internationalization strategy. At that time, Yangtze Optical Fibre敏锐地 seized the historic opportunity presented by the "Belt and Road" Initiative, precisely targeting emerging markets with strong demand for optical fibre but weak local manufacturing capabilities. In 2014, its first overseas cable joint venture factory was established in Myanmar. In 2015, a controlling subsidiary and its first overseas fibre factory were set up in Indonesia, with entry into South Africa in the same year. Subsequently, its footprint rapidly expanded to locations like Brazil and Poland. Looking back, Yangtze Optical Fibre was highly敏锐 in capturing the historic opportunities afforded by the era, deeply integrating its own development with China's "Belt and Road" Initiative. Its market布局 was precisely targeted at globalized emerging markets. From then on, from Southeast Asia to Africa, and later to South America and Europe, Yangtze Optical Fibre's global industrial footprint expanded rapidly. Consequently, revenue from overseas operations grew rapidly from approximately RMB 10 billion in 2017 to about RMB 30 billion in 2021, with its share of total revenue increasing from around 10% to 30%. In its early days, Yangtze Optical Fibre's revenue came almost entirely from the domestic market. The advancement of its internationalization strategy made its revenue structure more robust. Overall, this journey represents the global layout of a Chinese manufacturing enterprise evolving from product export to capacity export, and even technology export. It also witnesses how the company leveraged capital market forces to transform China's strategic opportunities into a far-sighted vision for long-term corporate development. Since then, Yangtze Optical Fibre's overseas revenue share has long been maintained at around 30%, effectively smoothing out the risks of cyclical fluctuations in a single domestic market. It even further increased to over 40% in 2025, successfully opening up new growth space. From a product perspective, optical transmission products (including cables, fibres, and preforms) consistently contribute the largest portion of revenue (over 60%), while the technologically more advanced fibre and preform business contributes the majority of profits. After all, technological iteration is the true foundation of Yangtze Optical Fibre's existence. Relying on the nationally established key laboratory positioned it within the national team for optical communication basic research. This laboratory also provided a top-tier platform and巨大的 market opportunities for subsequently攻克 a series of尖端 technological challenges, including hollow-core fibre. In 2018, Yangtze Optical Fibre was listed on the Main Board of the Shanghai Stock Exchange, becoming the first and currently the only "A+H" dual-listed company in China's optical fibre and cable industry. By 2024, Yangtze Optical Fibre had established production bases in 6 countries worldwide, with business覆盖 over 100 countries and regions.
Strategic Progress at Yangtze Optical Fibre Currently, Yangtze Optical Fibre has深耕 the field of hollow-core fibre for over a decade, achieving globally瞩目 results. After all, at顶级 conferences like OFC, the company has多次 released破纪录 research reports. More critically, Yangtze Optical Fibre not only leads globally in loss指标 but has also achieved decisive breakthroughs in规模化 preparation—achieving a single preform draw length exceeding 90 kilometres, directly paving the way for commercialization. Behind this lies Yangtze Optical Fibre's全链条 technological control, from independent synthesis of raw materials and高 precision capillary preparation to advanced drawing processes. Since 2025, the explosion of generative AI and large models has caused global computing power demand to surge exponentially. Bandwidth and latency for inter- and intra-data center connectivity have become key bottlenecks for the next stage of AI development. Meanwhile, in the field of financial high-frequency trading, a "one-microsecond" delay translates to millions of dollars in profit loss. The underlying reason is that traditional fibres use quartz glass for light transmission, where speed and loss have long reached physical limits (the Shannon limit). The颠覆性 nature of hollow-core fibre lies in its微 structure design, allowing light to travel in a接近 vacuum air core, thereby原理上跳出 material limitations. Consequently, Yangtze Optical Fibre has elevated the规模化 commercialization of hollow-core fibre to a core strategic level and has made substantive progress: 1) Financial Dedicated Line Deployment: In 2025, Yangtze Optical Fibre assisted China Mobile in building a hollow-core fibre line connecting the Shenzhen and Hong Kong stock exchanges, reducing cross-border securities trading transmission latency to within 1 millisecond. Simultaneously, the fibre loss on this line achieved 0.09dB/km, directly刷新 the global record for the lowest loss in commercial fibre. 2) Data Center Collaboration: Yangtze Optical Fibre is conducting深度 testing with leading internet companies and other computing power clients. Notably, its "AI Intelligent Computing Hub Solution" utilizes hollow-core fibre as a core technology, reducing communication latency within AI cluster internal networks by at least 50% or more. Overall, to accelerate global commercialization, Yangtze Optical Fibre has launched the "INFINITE-2030" plan. The goal is to collaborate with全球主流 operators and cloud service providers to promote over 50 commercial and pilot projects for hollow-core fibre by 2030. This means that特种 fibre products, represented by hollow-core fibre, are正在从单纯的传输介质 upgrade to a "photonics-enabled platform" integrating energy transmission and information sensing. Their application scenarios will also expand from communication networks to巨大的 market spaces like healthcare, energy, and autonomous driving. Consequently, a new network era driven by hollow-core fibre is正在到来. Currently, through vertical integration and横向拓展, Yangtze Optical Fibre has built a complete industrial ecosystem. It not only produces and sells various standard specifications of optical fibre preforms, fibres, and cables but also actively extends into fields like third-generation semiconductors, optical modules, and optical communication system integration. After all, the market most needs end-to-end solutions. Just as in Hubei province, Yangtze Optical Fibre's布局 in areas like Qianjiang, Hanchuan, and Huanggang has driven the formation of a trillion-yuan industrial cluster encompassing "Optics, Chips, Displays, Terminals, and Networks," which has become key to local economic development.
Conclusion In 2026, Yangtze Optical Fibre's total A+H market capitalization首次突破 RMB 200 billion, becoming the first listed company in Hubei to achieve this milestone. Particularly in the fourth quarter of 2025, the company's net profit attributable to shareholders saw a substantial year-on-year increase of 230%, with业绩弹性初步显现. The capital market敏锐地 captured this change, driving its stock price to achieve over a 10-fold increase in less than a year, ultimately reaching a market capitalization of RMB 200 billion. Looking back, Yangtze Optical Fibre has累计 delivered over 1.2 billion fibre-core kilometres of optical fibre. Meanwhile, its market share in the three main businesses of preforms, fibres, and cables has ranked first globally for ten consecutive years. Yangtze Optical Fibre possesses an annual preform production capacity of 4,000 tonnes (compared to Hengtong Optic-Electric's 3,000 tonnes, Zhongtian Technology's 2,000 tonnes, and烽火通信's 2,000 tonnes). It also masters three preform technologies: VAD, OVD, and PCVD, enabling flexible allocation of production capacity for single-mode, multi-mode, and特种型号 fibres to meet different market demands. This model构筑了极高的 profit foundation in the upstream core环节. After all, the突破 in market capitalization is merely a result and绝非 the终点. Yangtze Optical Fibre's true foresight is still reflected in its bets on next-generation technologies and the expansion of its industrial ecosystem. Consequently, at the 2026 Mobile World Congress in Barcelona, Yangtze Optical Fibre重磅发布 the hollow-core fibre brand "HollowBand." Currently, Yangtze Optical Fibre is早已不再 a单纯 optical fibre and cable manufacturer. Leveraging its vertically integrated全产业链 business model, global R&D strength led by hollow-core fibre technology, and forward-looking emerging market布局, it has successfully transformed into a key global node in the infrastructure for the future digital world. From the banks of the Yangtze River to the pinnacle of the world, over thirty-eight years, Yangtze Optical Fibre has woven a single, hair-thin optical fibre into an information network connecting China with the world, the present with the future. This is both a testament to the rise of Chinese manufacturing and reflects the industry trend where domestic enterprises will successively play various key roles in the global industrial landscape. In the foreseeable future, Yangtze Optical Fibre's commercial footprint is仍在 extending at the speed of light.
