Current Status of China-Pakistan Cross-Border Optical Cable

The China-Pakistan cross-border optical fiber cable is fully operational, connecting Rawalpindi in Pakistan to Khunjerab at the Chinese border, with ongoing plans to extend connectivity to Gwadar and Karachi.Project OverviewThe Pakistan-China Fiber Optic Project spans 820 kilometers within Pakistan, linking Rawalpindi to the Khunjerab Pass at the China-Pakistan border, and further connecting to Urumqi in China's Xinjiang region . The project was inaugurated in July 2018 and was constructed as part of the China–Pakistan Economic Corridor (CPEC), with Huawei and China Telecom collaborating with Pakistan's Special Communications Organization (SCO) for engineering, procurement, and construction . The cable provides 3G and 4G services and establishes a direct terrestrial link between Pakistan and China, reducing reliance on undersea cables .Technical and Operational DetailsRoute Distribution: 466.54 km in Gilgit-Baltistan, 287.66 km in Khyber Pakhtunkhwa, 47.56 km in Punjab, and 18.2 km in Islamabad Capital Territory .Backup Link: A 172 km aerial optical fiber cable from Karimabad to Khunjerab ensures redundancy .Infrastructure: Includes 9 intensive light multiplexing rooms and modern equipment for signal transmission .Financing: 85% of the project cost is financed through a concessional loan from the Exim Bank of China, with the remaining 15% funded by Pakistan .Strategic SignificanceThe cable is a key component of Pakistan's Digital Silk Road, enhancing digital connectivity, cybersecurity, and data transfer efficiency between Pakistan, China, and Central Asia . It provides:Lower latency for data transfer to China and Central Asia.Enhanced redundancy, reducing outages from undersea cable disruptions.Support for national digital initiatives, including the National Fiberization Policy and FTTH rollout .Future ExpansionPhase II of the project aims to extend the cable southwards to Gwadar and Karachi, creating a complete north-south digital corridor in Pakistan . This expansion will integrate data centers and cloud infrastructure, supporting digital sovereignty, e-governance, and business analytics within Pakistan . In summary, the China-Pakistan cross-border optical cable is fully operational, forming a critical backbone for Pakistan's digital infrastructure, with ongoing plans to expand connectivity to southern ports and enhance the country's role in regional digital networks.
