Tunisia Lands a Direct Undersea Link to Europe as Africa's Subsea Cable Race Intensifies

The activation of the ViaTunisia cable establishes a new high-capacity digital corridor between Marseille, France, and Bizerte, Tunisia. This 1,050-kilometre cable represents the first active segment of the Medusa Submarine Cable System, a broader undersea network currently under construction across the Mediterranean.

Orange serves as the landing party at both ends of the link, connecting the cable directly into its infrastructure in Marseille through a fibre ring that links its data centres in the city. While the immediate utility is increased capacity, the strategic significance lies in the broader Medusa Submarine Cable System. Owned by AFR-IX Telecom, the full network is designed to span 8,760km and eventually reach up to 17 landing points across the Mediterranean coasts, including France, Spain, Italy, Portugal, Greece, Cyprus, and Malta in the north, and Tunisia, Morocco, Algeria, Libya, and Egypt in the south.

The architecture of Medusa is built on an open-access model, allowing any regional telecom provider to connect to the system. This expansion is partially supported by the European Union, which co-financed the ViaTunisia segment through its Connecting Europe Facility (CEF) Digital programme, covering 30% of construction and management costs via a grant agreement signed in December 2022.

This deployment is a direct response to the fragility of existing African connectivity. The necessity of redundant routes became clear in March 2024, when several African countries experienced internet disruptions following simultaneous damage to four major undersea cables near the Ivory Coast. Such outages impact mobile networks, banking, and digital services in Nigeria and other regions. Further disruptions occurred when cables connecting South Africa and Kenya went offline, following damage in the Red Sea.

For the African continent, the Medusa system is an exercise in infrastructure resilience. The shift toward more subsea routes is a move to mitigate the systemic risks posed by single-point failures in undersea architecture. As demand from cloud services and artificial intelligence grows, the ability to maintain connectivity through diverse routing becomes a requirement for economic stability.

The question for regional operators is no longer just about capacity, but about how effectively they can integrate into these new, open-access networks to prevent the next widespread outage.
