Communication fiber optic cable North Korea

North Korea's fiber optic network connects major cities domestically and links internationally to China and Russia, forming the backbone of its controlled internet and telecommunications infrastructure.

Domestic Fiber Optic Network

North Korea began deploying fiber optic cables in the mid-1990s, with the first cable connecting Pyongyang to Hamhung in September 1995. By 1998, a cable linked Pyongyang with Sinuiju on the Chinese border, and by 2000, additional connections extended to Nampo, Rajin-Songpa, and Hunchun along the Sea of Japan coast. Fiber optic lines are often laid along railway tracks and major roads, facilitating connectivity between government ministries, industrial centers, and urban areas.

The domestic intranet, known as Kwangmyeong, relies heavily on these fiber optic connections to link all ministries and key institutions.

International Connectivity

North Korea's main international internet access is through a fiber optic cable connecting Pyongyang with Dandong, China, operated by China Unicom. Additionally, a TransTeleCom cable from Russia crosses the Tumen River via the Korea-Russia Friendship Bridge, connecting to North Korea's east coast and ultimately linking to Pyongyang. These international links are critical for controlled access to the global internet and for facilitating limited cross-border communications.

Mobile Networks and Fiber Integration

North Korea has two mobile operators, Koryolink and Kangsong NET, with 4G services launched in 2023. Fiber optic infrastructure supports these networks, enabling faster data transmission and improved service reliability. Fiber optics also underpin the country's digital payment systems and internal communication networks, although international roaming is restricted.

Strategic and Socio-

Economic Implications

Fiber optic deployment in North Korea is not only a technological upgrade but also a tool for state control over information. Enhanced fiber networks improve internal communications, support economic activities, and may facilitate selective international connectivity. However, due to the country's secrecy, the full extent and technical specifications of the network remain largely unknown.

In summary, North Korea's fiber optic network forms a controlled, strategic backbone connecting domestic cities, government institutions, and international links to China and Russia, supporting both telecommunications and state-managed internet access.
