The East African Marine System (TEAMS): A Key Link Between East Africa and the Middle East
The East African Marine System (TEAMS) is a submarine cable connecting
Fujairah in the United Arab Emirates to
Mombasa in Kenya. Spanning approximately 5054 kilometers, it serves as a critical telecommunications corridor for East Africa, linking the region to international networks via the Middle East. It is owned by TEAMS Ltd. and e&, and has been listed as in service since its recorded ready-for-service (RFS) year of 2009.
What makes TEAMS notable is the absence of publicly disclosed technical specifications, such as design capacity, fiber pair count, and supplier details. This lack of transparency is unusual for a cable of its scale, leaving room for speculation about its technological underpinnings. Additionally, latency measurements from live internet probes reveal significant differences between theoretical and observed values, suggesting complex routing and equipment factors at play.

Route
TEAMS connects Fujairah on the eastern coast of the United Arab Emirates to Mombasa, Kenya’s principal port city on the Indian Ocean. Fujairah is a major hub for submarine cables, hosting numerous systems such as AAE-1, BBG, and
SeaMeWe-5, which collectively link the Middle East to Europe, Africa, and Asia. Mombasa, similarly, is a critical landing site for cables like
2Africa, SEACOM, and
PEACE Cable, making it a central node for East African connectivity.
The cable’s route traverses the Arabian Sea and the western Indian Ocean, a corridor known for its strategic importance in linking Africa to global telecommunications networks.
Why it was built and what it carries
TEAMS was conceived to address East Africa’s growing demand for high-speed internet and international connectivity. Before its deployment, the region relied heavily on satellite communications, which were expensive and offered limited bandwidth. By connecting Kenya directly to the UAE, TEAMS provided a faster, more cost-effective alternative, enabling economic growth and digital transformation in the region.
The cable supports a range of telecommunications services, including internet, voice, and data traffic. Its direct route to Fujairah also ensures low-latency connections to Middle Eastern and Asian networks, although the lack of disclosed design capacity makes it difficult to assess its full capabilities.
History: what can be established
TEAMS was recorded as ready for service in 2009, according to GeoCables data. No conflicting RFS dates have surfaced from industry sources, suggesting general agreement on its operational timeline. Its deployment marked a significant milestone for Kenya, which previously depended on the SEACOM cable and satellite links for international connectivity.
The cable’s construction was part of a broader effort to integrate East Africa into the global digital economy. It was financed and managed by a consortium led by TEAMS Ltd., with e& (formerly Etisalat) as a key stakeholder. While specific details about its supplier and construction timeline remain undisclosed, its operational status has been consistently maintained.
Capacity and technology
Publicly available information does not disclose TEAMS’ design capacity, fiber pair count, or supplier details. Without operator documentation, attributing specific technical parameters would be speculative. However, given its deployment in 2009, it likely uses optical fiber technology typical of submarine cables from that era, with repeaters spaced along the route to amplify signals.
The absence of disclosed capacity metrics makes it difficult to compare TEAMS to other cables in the region. Its role as a regional connector, however, suggests that it was designed to handle substantial traffic volumes to support East Africa’s growing telecommunications needs.
Latency: the physics
The computed theoretical one-way latency for TEAMS is approximately 24.8 milliseconds over its 5054-kilometer wet segment, with a round-trip time (RTT) floor of 49.5 milliseconds. These values assume light propagation speeds of 200,000 to 204,000 kilometers per second in optical fiber.
However, live latency measurements from remote probes show much higher values. Fujairah to Mombasa exhibits a minimum RTT of 220.5 milliseconds, while Mombasa to Fujairah shows a minimum of 74.3 milliseconds. Average RTTs are even higher, at 292.8 milliseconds and 89.2 milliseconds, respectively. These discrepancies highlight the impact of terrestrial routing, terminal equipment, and network congestion on real-world performance.
Redundancy: what happens if it breaks
TEAMS operates in a corridor with multiple alternative cables, ensuring redundancy in case of outages. At Fujairah, alternatives include AAE-1,
SeaMeWe-4, and
IMEWE, among others. Mombasa is similarly well-connected, with cables like 2Africa and EASSy providing backup routes.
Standard industry practices for submarine cable repair would apply to TEAMS. Faults are typically located using underwater surveys, and repair ships equipped with specialized tools are deployed to restore service. The presence of alternative cables minimizes the impact of outages on regional connectivity.
Bottom line
- TEAMS spans 5054 kilometers, connecting Fujairah (UAE) to Mombasa (Kenya).
- Ready-for-service year: 2009 (no conflicting data).
- Owners: TEAMS Ltd., e&.
- Design capacity, fiber pairs, supplier, and technology details are not publicly disclosed.
- Theoretical RTT floor: 49.5 milliseconds; real-world latency is significantly higher.
- Redundancy provided by alternative cables at both landing points.
