Kazakhstan and Azerbaijan are jointly implementing a 380–400 km submarine fiber-optic cable across the Caspian Sea, set to launch in 2026 with a capacity of 400 Tbit/s.

Project Overview

The Trans-

Caspian fiber-optic cable (FOC) project is a strategic initiative linking Aktau, Kazakhstan, and Sumqayit, Azerbaijan via an underwater cable along the Caspian Sea seabed. Initially proposed in 2019, the project aims to enhance digital connectivity between Europe and Asia, reduce latency, and support high-speed international data transmission. The cable is part of the broader Digital Silk Way initiative, designed to streamline data transit across Eurasia and attract foreign investment into the regional digital economy.

Technical Specifications

Length: Approximately 380–400 kilometers Capacity: At least 400 terabits per second, supporting large-scale data transfers and future digital demands Infrastructure: Includes beach manholes and cable landing stations on both coasts, with the seabed route mapped for depth, terrain, underwater currents, and geological conditions Construction: Two parallel fiber-optic lines are being laid to ensure redundancy and reliability Timeline and ImplementationActive construction phase: Currently underway, with specialized survey vessels operating from the Kazakh port of Bautino to finalize the cable route Expected launch: Third quarter of 2026, with full operational capacity by the end of 2026 Project cost: Estimated at $50.

6 million, jointly funded by Kazakhtelecom and AzerTelecom Strategic ImportanceThe project is designed to: Enhance regional digital connectivity and internet quality in Kazakhstan, Azerbaijan, and neighboring regions Reduce latency and improve stability for international data traffic Support economic cooperation and attract foreign investment in the digital sector Serve as a critical link in the Digital Silk Way, connecting Europe and Asia through a high-speed, low-latency corridor Participating CompaniesKazakhtelecom: Kazakhstan's national telecommunications operator, leading the project on behalf of Astana AzerTelecom: Azerbaijan's backbone internet provider, part of NEQSOL Holding, partnering in the joint venture Current StatusCoastal surveys and site selection for landing stations are complete Seabed mapping and geological assessments are ongoing to ensure technical feasibility and optimal routing The project is positioned to become a digital bridge between Asia and Europe, supporting sustainable connectivity and regional digital transformation This Trans-Caspian optical cable represents a landmark infrastructure project for Kazakhstan, enhancing its role as a key digital gateway in Eurasia while fostering regional collaboration and technological advancement.
