Mongolian optical cable laying

Mongolia has been actively expanding its fiber optic network using underground, aerial, and micro-trenching methods, with 12-core cables widely deployed for high-speed connectivity.

Overview of Fiber Optic Infrastructure

Mongolia relies heavily on fiber optic communications for both domestic and international connectivity, linking with China and Russia and connecting major urban centers through multiple providers . The government has supported network expansion through policies and the Universal Service Obligation Fund, aiming to deliver essential communications to remote areas . Fiber optic networks are increasingly used in telecommunications, Internet backbones, data centers, and smart city projects .

Types of Cables and Standards

The most commonly used optical cable in Mongolia is the 12-core fiber optic cable, which provides high-speed data transmission and is suitable for smart buildings and industrial applications . Cables are imported from multiple suppliers, with Moncable Co., Ltd supplying nearly half of the market . Installation follows Mongolian standards such as MNS 5207:2023 for fiber optic cable installation and MNS 6597:2016 for underground armored cables .

Installation Methods

1. Underground Installation: Fiber cables are laid in trenches or communication wells, often armored for protection. This method is cost-effective and minimizes in-service damage .
2. Micro-Trenching: A narrow, shallow trench is created in urban areas to minimize disruption. Cables are placed and sealed within the trench .
3. Aerial Installation: Cables are mounted on poles or buildings, including high-voltage or lighting poles for special-purpose lines .

Recent Projects

• Boroo Gold Mine, Selenge Province (2021): Fiber optic cable installed for industrial operations .
• Tsagaan-Owoo to Steppe Gold LLC Camp, Dornod Province (2022): Long-distance fiber installation completed .
• Shine Khovd Production and Technology Park (2023): Fiber optic cables and well channelization finalized .
• Urban Infrastructure: Communication wells and canalization lines are being expanded in cities to support growing fiber networks .

Applications and Benefits

Fiber optic networks in Mongolia support high-speed Internet, smart city infrastructure, surveillance systems, and industrial automation . The use of 12-core cables allows for future-proof scalability, high-density connections, and reliable performance in both indoor and outdoor environments . These networks are critical for connecting remote areas, improving broadband access, and supporting mobile and fixed-line services . In summary, Mongolia's optical cable laying combines modern installation techniques, adherence to national standards, and strategic deployment in urban and rural areas, ensuring robust and scalable fiber optic connectivity across the country.
