The Trans-Caspian Fiber-Optic Cable Line is shaping a new direction for the strategic partnership between Azerbaijan and Kazakhstan. Beyond strengthening digital connectivity between Central Asia and the South Caucasus, the project expands the region’s capabilities in international data exchange. The 380-kilometer subsea fiber-optic cable laid across the bed of the Caspian Sea between Aktau and Sumgayit features a projected capacity of at least 400 terabits per second. This infrastructure aims to link Kazakhstan and other Central Asian nations through Azerbaijan to the digital networks of Türkiye and Europe. The project is primarily significant for diversifying international data transmission routes, enhancing communication resilience, and expanding technological capacity.
These views were expressed by Aliya Kanatova, Director of the Center for Digital Data and Solutions and Associate Professor at Astana IT University, in a statement to AZERTAC.
She noted that in the modern world, uninterrupted digital connectivity is a vital prerequisite for economic development and international cooperation. Consequently, the new cable line will broaden access for regional countries to global digital networks.
The expert emphasized that Azerbaijan and Kazakhstan are actively building the new digital architecture of the Middle Corridor. Kazakhstan is advancing the Central Asian segment of the route, while Azerbaijan shapes the western continuation of the Trans-Caspian line, providing access to European networks via the South Caucasus and Türkiye. It is the convergence of these capabilities that turns this joint infrastructure endeavor into a digital bridge between Asia and Europe. The new cable line grants Kazakhstan additional access to international digital networks, enhances the resilience of its national digital infrastructure, and solidifies the country’s position as a connector between China, Central Asia, and Europe. Furthermore, the project fosters favorable conditions for the development of data centers, cloud services, and artificial intelligence infrastructure. In this regard, the “Data Center Valley” initiative underway in Ekibastuz holds special significance.
Alongside the Cable Line, a Digital Ecosystem Must Be Built
A. Kanatova noted that while the subsea cable establishes a critical infrastructure foundation, the long-term results of the project will depend heavily on the digital ecosystem formed around it. To achieve this, data centers, internet exchange points (IXPs), cloud platforms, backup communication channels, and cybersecurity services must be developed. Competitive tariffs, predictable regulatory frameworks, and harmonized mechanisms for cross-border data transmission are paramount. In other words, laying the cable represents only the initial phase. In the subsequent phase, Azerbaijan and Kazakhstan must ensure its commercial efficiency, attract international operators and tech companies, and harmonize technical standards, infrastructure access terms, and security requirements.
“A set of concrete metrics will prove decisive for international business. These include data transmission pricing, bandwidth capacity, signal latency, connection reliability, and the availability of redundant routes. If the new channel proves commercially competitive, it can capture a substantial share of the growing data traffic flowing between Asia and Europe. Otherwise, if an adequate digital ecosystem is not created around it, the line—though remaining a vital infrastructure asset—could become an underutilized asset. Therefore, the project’s success will be measured not only by its technical capabilities, but also by its economic efficiency and market competitiveness,” she noted.
Aliya Kanatova emphasized that the commissioning of the Trans-Caspian Fiber-Optic Cable Line fundamentally transforms the nature of the Middle Corridor. She stated that whereas the route’s competitiveness was previously evaluated primarily by cargo transit times, transport capacity, and logistics services, its digital capabilities are now coming to the fore. A modern international corridor must simultaneously facilitate the movement of goods, energy, financial flows, and data. The more closely coordinated these dimensions become, the greater the economic and strategic value of the route. The Trans-Caspian line elevates cooperation between Azerbaijan and Kazakhstan to a new tier. While partnership was previously anchored primarily in transport, trade, and energy, long-term technological collaboration is now added to these domains. This requires ongoing coordination among telecom operators, regulatory bodies, cybersecurity centers, and tech firms in both countries. The project also lays the groundwork for deeper integration of other Central Asian nations into this corridor.
The Primary Goal is to Create Added Economic Value
The expert believes that the project’s success cannot be measured solely by the volume of data transmitted across the Caspian Sea. The core objective is whether Azerbaijan and Kazakhstan can turn digital transit into a source of added economic value. This encompasses establishing data processing centers, cloud platforms, AI solutions, financial technologies, and cybersecurity services. Should the necessary infrastructure and a favorable business environment be established, both countries can derive revenue not only from data transit, but also from its storage, processing, and protection. This would stimulate new investments, advance digital services, and increase demand for highly qualified specialists. For a long time, the Caspian Sea was viewed as a natural boundary between Central Asia and the South Caucasus. Now, it is becoming a digital bridge. Nevertheless, the cable line merely provides new opportunities. Translating these opportunities into a sustained strategic advantage will depend entirely on the technological and economic ecosystem built around it.
