Azerbaijan, Kazakhstan, and Turkmenistan Push Ahead with Digital Corridor Across Caspian

Marine research is underway to determine the optimal route for the Trans-Caspian fiber-optic cable, a vital component of the ambitious “Digital Silk Way” initiative aimed at building a high-capacity digital corridor connecting Europe and Asia, Media.az reported. The ongoing survey, which includes shoreline assessments and detailed seabed analysis, will define the shortest, safest, and most environmentally sustainable path for the cable. Research began simultaneously from the Azerbaijani and Kazakhstani coasts and is expected to take up to four weeks. Emil Masimov, Chairman of AzerTelecom’s Board, visited the Turkan research vessel, where the survey is being conducted. During his visit, he reviewed the ship’s technical capabilities and met with the crew and engineering teams. “The Trans-Caspian cable project is progressing rapidly. With the launch of this marine survey, we are entering a crucial phase of construction,” Masimov said. “This step will boost regional digital connectivity and position the Caspian Sea as a key link in global digital infrastructure. Both Azerbaijani and Kazakh teams are using cutting-edge technology and professional expertise, and I am confident the work will be completed on schedule.” The 380-kilometer underwater cable will run from Sumgayit, Azerbaijan, to Aktau, Kazakhstan, and is expected to offer a transmission capacity of up to 400 terabits per second. Once operational, the line will significantly strengthen intercontinental data flows. Construction is scheduled to be completed by the end of 2026. Kazakhtelecom is leading the project on the Kazakh side, while U.S.-based Pioneer Consulting is providing technical oversight and consultancy services. The Trans-Caspian cable is a central element of the broader “Digital Silk Way” initiative, which envisions a modern telecommunications corridor passing through Azerbaijan, Georgia, Turkey, Kazakhstan, and Turkmenistan. The project aims to deliver high-speed, low-latency data routes that promote regional cooperation, digital integration, and sustainable economic development.

Kazakhtelecom CEO Confirms 2026 Launch of Caspian Submarine Cable Project

Kazakhstan and Azerbaijan have entered the active implementation phase of the long-anticipated submarine fiber-optic cable (SFOC) project across the Caspian Sea. According to Bagdat Mussin, CEO of Kazakhtelecom JSC, the underwater cable system is scheduled for completion and launch by the end of 2026. First proposed in 2019, the project involves the construction of two parallel fiber-optic lines, spanning approximately 380 to 400 kilometers, to connect the digital infrastructures of Kazakhstan and Azerbaijan. Originally, Kazakh telecom operators Transtelecom and KazTransCom participated alongside Azerbaijan’s AzerTelecom. However, by 2022, the Kazakh companies had exited the venture, and in 2023, Kazakhtelecom assumed the lead role on behalf of Astana. On August 22, 2023, Kazakhtelecom and AzerTelecom formalized their partnership by signing a joint venture agreement in Amsterdam. Mussin stated that national operators have now completed site surveys of the coastal infrastructure, identifying locations for both a beach manhole and a cable landing station. A specialized survey vessel, currently operating from the Kazakh port of Bautino, is mapping the seabed to assess depth, terrain, underwater currents, and geological conditions to finalize the cable route. “The bridge's capacity is designed to meet future demands and will support at least 400 Tbit/s. When the first byte of data travels through this artery, the Caspian will become a unique digital bridge between Asia and Europe,” Mussin said. As previously reported by The Times of Central Asia, the total cost of the project is estimated at $50.6 million. The cable is part of a wider regional initiative to advance digital transformation and sustainable connectivity across Eurasia.
