Monaco has completed a major fiber optic rollout, combining terrestrial and submarine cable installations with advanced trenchless and specialized equipment to provide high-speed connectivity across the Principality.

Terrestrial Fiber Optic Deployment

Monaco Telecom has completed the installation of 210 kilometers of fiber optic network to replace the old copper infrastructure, aiming to connect every home and business with high-speed internet capable of up to 10 Gbps . The deployment involved two main stages:

• Horizontal deployment: Laying fiber along streets and public areas, which has been fully completed.
• Vertical deployment: Connecting individual apartments and buildings, progressing according to building authorizations, with 62% of eligible apartments connected as of the latest updates . The installation requires specialized technical expertise, including precise handling of fiber connectors (ST/SC/LC/MTRJ) and integration with existing telecom networks, ensuring stable and continuous data flow for both residential and professional users .

Trenchless Installation Techniques

To minimize disruption in Monaco's dense urban environment, trenchless methods were employed. For example, during the renovation of a drinking water pipeline along major traffic arteries, fiber optic cables were laid simultaneously using the Primus Line® system, which allows flexible insertion through bends and tight spaces without open excavation . This method preserves existing infrastructure while maintaining high-speed connectivity and ensures minimal impact on traffic and pedestrian areas.

Submarine Cable Connections

Monaco is also connected to global undersea fiber optic networks via submarine cable landing stations. These stations link the Principality to international networks, providing redundancy and high-capacity data transfer for both commercial and governmental needs . Submarine cables are critical for Monaco's digital infrastructure, supporting international communications and enhancing the country's attractiveness for business and teleworking.

Specialized Cable Laying Equipment

For both terrestrial and offshore projects, advanced cable-laying equipment is used. Royal IHC provides systems such as the Sea Stallion FibrePro and Fibre Pro Max ploughs, LARS, and tow winches, which allow precise tension control, automated operations, and real-time monitoring during installation . These systems are adaptable to different vessel types and can operate in deep water or complex urban environments, ensuring reliable and efficient fiber deployment.

Summary

Monaco's optical cable construction combines high-speed fiber rollout, trenchless urban installation, and submarine cable connectivity, supported by state-of-the-art equipment and technical expertise. This integrated approach ensures that the Principality achieves ultra-fast, reliable internet access for residents, businesses, and international communications, while minimizing disruption to urban life and existing infrastructure .
