Equiano submarine cable
Price and availability check
The invisible infrastructure of global connectivity
The Equiano submarine cable is a cable system financed and operated by Google that connects Europe directly with West Africa and South Africa. Named after the Nigerian-British abolitionist Olaudah Equiano, the cable is symbolic of the growing digital connection between Europe and Africa. As one of the first privately funded hyperscaler cables on the African route, Equiano sets new standards in terms of capacity and technology and will fundamentally improve digital connectivity for millions of people along the West African coast. Submarine cables like Equiano form the invisible foundation of global data traffic, with over 99% of international data flowing through them rather than through satellites or the cloud.
Route & connection
Equiano connects Portugal in the north with South Africa in the south and runs along the West African coast. Along the route, the cable lands in Nigeria, Togo, Ghana, Namibia and South Africa, as well as the Canary Islands and São Tomé and Príncipe. The direct connection between Europe and South Africa on a single cable route makes Equiano a strategically valuable system for companies wishing to connect both the West African and South African markets.

What is the Equiano cable?
Equiano is a submarine cable system spanning around 15,000 kilometers, financed and operated by Google, that has connected Portugal directly with West Africa and South Africa since September 2022. Named after the Nigerian-British abolitionist Olaudah Equiano, the system was one of the first hyperscaler-owned cables on the African route. With 12 fiber pairs based on space division multiplexing (SDM), Equiano reaches a design capacity of 144 Tbit/s, around 20 times the capacity of the previously newest cable system on this route. The system was built by Alcatel Submarine Networks (ASN).

Equiano submarine cable

Technology & capacity
Equiano uses state-of-the-art fiber optic technology and is designed for a capacity of up to 144 Tbit/s, which exceeds the capacity of existing cable systems on the African route many times over. Essentially, these are the technological features:
- SDM (Space Division Multiplexing): Equiano is one of the first cable systems on the Africa route to use SDM technology, which enables significantly higher capacity per cable.
- Optical switching technology: Equiano has optical switches at the landing points that enable flexible and efficient distribution of capacity along the route.
- The latest generation of fibre optic technology for minimal signal loss and optimized latency on the entire Europe-Africa route.

Frequently asked questions about the Equiano cable
Equiano connects Portugal with West Africa and South Africa, landing at Sesimbra (Portugal), Lome (Togo), Lagos (Nigeria), Rupert’s Bay on St. Helena, Swakopmund (Namibia) and Melkbosstrand near Cape Town (South Africa). For St. Helena, Equiano was the very first fiber-optic submarine cable connection ever, the island had previously relied entirely on satellite links. In total, the cable connects six landing points on a continuous route of around 15,000 kilometers.
Equiano reaches a design capacity of 144 Tbit/s across 12 fiber pairs based on space division multiplexing (SDM). This gives the system around 20 times the capacity of the previously newest cable system on the West African route. Equiano was also one of the first submarine cables worldwide to use optical switching at the fiber-pair level rather than the usual wavelength-level switching.
Equiano reached its final destination with the landing in South Africa in September 2022, with individual sections such as St. Helena and Nigeria already active in 2021 and early 2022. The system is fully owned by Google, making it one of the few major hyperscaler-owned cables on the African route. Equiano was built by Alcatel Submarine Networks (ASN).
It depends on your capacity and redundancy strategy. Equiano, as the newest system, offers by far the highest capacity. ACE covers the widest route along the West African coast with 24 connected countries. WACS is an established alternative with a direct connection to the United Kingdom. SAVECALL compares all options for your specific route.
For genuine redundancy, you should book capacity on at least two physically separate cable systems, for example Equiano and ACE or Equiano and WACS, so that damage to one system does not cause a complete loss of connectivity. Since Equiano, as a sole Google cable, has a different ownership structure than the consortium cables ACE and WACS, this also results in different commercial access routes. SAVECALL reviews this for your existing connectivity setup.
SAVECALL has direct market access to capacity on Equiano and sources IRU structures and leased capacity models tailored to your needs, without reseller chains and with transparent price benchmarking. Book a free consultation and we will analyze your current connectivity strategy and show which capacity options on Equiano are right for your company.
