The invisible infrastructure of global connectivity

SEACOM was Africa’s first submarine broadband cable when it went into operation on July 23, 2009. It connects East Africa and South Africa with Europe via India and fundamentally changed the continent’s connectivity landscape: within months, bandwidth prices in the region fell by up to 90 percent. SEACOM was also the first privately financed, carrier-independent cable system in the region. The system is now fully operational and directly supplies carriers, ISPs and enterprise customers in six countries. SEACOM is already planning the next generation with SEACOM 2.0: a 25,000 km system with 48 fiber pairs designed for AI workloads and next generation networks.

Route & connection

SEACOM connects Mtunzini (South Africa) via Maputo (Mozambique), Dar es Salaam (Tanzania), Mombasa (Kenya) and Djibouti with Mumbai (India) and Marseille (France). On the Egypt-India section, the system shares physical segments with the Tata-TGN Eurasia system. The total length is around 17,000 kilometers.

SAVECALL as access to SEACOM

SEACOM is a privately managed system without state consortium interests. This makes the negotiations more direct and the structures more flexible than with traditional carrier consortia. SAVECALL makes targeted use of this advantage: We negotiate capacity on an equal footing with the operator, know the available capacity models and provide full price benchmarking against EASSY, 2Africa and other East Africa options. For companies with operations in Kenya, Tanzania, Mozambique or South Africa, SEACOM is often the most efficient solution. SAVECALL assesses this in the context of your overall network needs and then sources the right carrier on the right terms.

The result for our customers:

  • Direct capacity access to SEACOM without reseller chains
  • Negotiation of IRU structures and leased capacity models
  • Transparent price benchmarking against all available alternatives
  • True route diversity through independent redundancy planning
  • Clear SLAs and ongoing capacity management

Vendor-neutral assessment: SEACOM, EASSY and 2Africa all aim to provide high-performance connectivity for East Africa, but differ significantly in build year, reach and capacity. As an independent capacity broker, SAVECALL assesses all three systems neutrally and selects the right solution based on location, redundancy needs and budget.

Frequently asked questions about the SEACOM cable

Which route does SEACOM connect?

SEACOM connects Mtunzini in South Africa via Maputo in Mozambique, Dar es Salaam in Tanzania, Mombasa in Kenya and Djibouti with Mumbai in India and Marseille in France. Between Djibouti and India, the system shares physical segments with the Tata TGN-Eurasia system via Egypt and Saudi Arabia. The total length is around 17,000 kilometers.

What is the capacity of SEACOM?

SEACOM has 2 fibre pairs with a design capacity of 12 Tbit/s. Around 4.2 Tbit/s of that is currently lit, following several capacity upgrades since entering service in 2009. Over 150 underwater optical amplifiers handle signal transmission along the entire length of the system.

Who operates SEACOM and since when has it been in service?

SEACOM has been in service since July 23, 2009, and was Africa’s first broadband submarine cable as well as the region’s first privately financed, carrier-independent system. SEACOM is operated by a private consortium made up of Industrial Promotion Services, Remgro, Sanlam and Convergence Partners, with no state consortium structure. The cable was built by SubCom.

SEACOM, EASSY or 2Africa: which cable is right for me?

All three systems connect East Africa to the world, but they differ significantly in reach and capacity. SEACOM offers a direct Marseille connection as Africa’s first private cable. EASSY provides the densest coverage of the East African coast with nine landing points, including Madagascar and Comoros. 2Africa circles the entire continent and offers by far the highest capacity at up to 180 Tbit/s. The right choice depends on location, budget and redundancy strategy.

What is SEACOM 2.0?

SEACOM 2.0 is the announced next generation of the system: a cable of around 25,000 kilometers with 48 fibre pairs, connecting Europe, the Middle East, Africa and Asia. The system is specifically designed for AI workloads, cloud applications and real-time data services, and aims to significantly reduce connectivity costs in the region. A concrete entry-into-service date has not yet been set.

How do I get capacity on SEACOM?

SEACOM is a privately run system without state consortium interests, which enables direct negotiations and flexible structures. SAVECALL negotiates capacity on an equal footing with the operator, knows the available capacity models and provides full price benchmarking against EASSY, 2Africa and other East Africa options.
