The invisible infrastructure of global connectivity
The invisible infrastructure of global connectivity
The Amitié submarine cable is one of the most powerful transatlantic cable systems in the world, connecting Europe and North America with a capacity that meets the growing demands of modern business communications. As one of the newest transatlantic cable systems, Amitié sets new standards in terms of bandwidth, latency and reliability. Submarine cables like Amitié 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
The Amitié cable connects the east coast of the USA (Virginia Beach) with France (Brest) and the United Kingdom (Bude) and thus offers a direct connection to the most important European data centers and Internet nodes. The total length of the cable is around 6,800 kilometers and bridges the North Atlantic on one of the world’s busiest data routes.

What is the Amitié cable?
The Amitié cable is a transatlantic submarine cable spanning around 6,800 kilometers that connects the United States via Lynn, near Boston, with France (Le Porge, near Bordeaux) and the United Kingdom (Bude). It entered service in 2023 and reaches a design capacity of up to 400 Tbit/s across 16 fiber pairs, making it the highest-capacity transatlantic cable ever deployed at launch. Amitié is operated by a consortium of Meta, Microsoft, Vodafone, Orange and Aqua Comms, and was built by Alcatel Submarine Networks. Its open cable design and SDM technology allow capacity to be flexibly split between the three landing points, making Amitié one of the key redundancy options on the North Atlantic route.

Amitié submarine cable

Technology & capacity
The Amitié cable system uses state-of-the-art fiber optic technology and achieves a total capacity of up to 400 Tbit/s, making it one of the highest-capacity transatlantic connections ever. Essentially, these are the technological features:
- SDM (Space Division Multiplexing): A modern technology that enables significantly more fiber pairs per cable and thus considerably increases capacity compared to older systems.
- Open Cable Design: Amitié uses an open cable system that enables consortium partners to use their own transmission technology and thus ensure maximum flexibility.
- The latest generation of fibre optic technology for minimal signal loss and optimized latency over thousands of kilometers of cable.
Provider Overview
SAVECALL as access to Amitié
As one of the most modern transatlantic cable systems, Amitié is designed to meet the requirements of the coming decades. With its open cable design and a capacity of up to 400 Tbit/s, it will play a key role in global data traffic in the long term and meet the constantly growing demand for transatlantic bandwidth. For cloud providers, financial institutions and companies with latency-sensitive applications, Amitié is already one of the most attractive transatlantic options on the market today.
However, access to capacity on premium cables such as Amitié requires direct wholesale partnerships, in-depth market knowledge and negotiating experience. This is exactly where SAVECALL comes in. We have direct market access, source bandwidth on Amitié without detours via reseller chains and negotiate IRU structures and leased capacity models on an equal footing with the relevant carriers.
The result for our customers:
- Clear SLAs and ongoing capacity management
- Direct capacity access to Amitié without reseller chains
- Transparent price benchmarking and market data
- True route diversity and independent redundancy planning
- Negotiation of IRU structures and leased capacity models

Amitié compared
Several modern cable systems compete for the same demand from hyperscalers, financial institutions and companies with latency-sensitive applications on the North Atlantic route. For procurement decisions, raw capacity matters less than which landing points, route diversity and capacity models fit an organization’s own redundancy concept. The comparison below positions Amitié against the established alternatives MAREA, Dunant and Grace Hopper.
| Criterion | Amitié | MAREA | Dunant | Grace Hopper |
|---|---|---|---|---|
| Route | US (Lynn, Massachusetts), France (Le Porge), UK (Bude) | US (Virginia Beach), Spain (Bilbao) | US (Virginia Beach), France (Saint-Hilaire-de-Riez) | US (New York), UK (Bude), Spain (Bilbao) |
| Design capacity | up to 400 Tbit/s | around 200 Tbit/s | 250 Tbit/s | 352 Tbit/s |
| In service since | 2023 | 2018 | 2021 | 2022 |
| Fiber pairs | 16 | 8 | 12 | 16 |
| Strength | highest capacity, three landing points in three countries | southernmost North Atlantic route, physically separate from older cables | first SDM cable with 12 fiber pairs, direct Google connectivity | three landing points including Spain, high route diversity |
Vendor-neutral assessment: SAVECALL does not rank Amitié, MAREA, Dunant and Grace Hopper against each other, but views them as complementary building blocks for a resilient North Atlantic connection. Which cable or combination makes sense for a business depends on the required landing points, the desired route diversity and existing carrier relationships. As a carrier-neutral consultancy, we source capacity across all relevant systems and recommend purely based on actual requirements.

Frequently asked questions about the Amitié cable
Amitié connects the United States via Lynn, near Boston, with France at Le Porge, near Bordeaux, and the United Kingdom at Bude over a route of around 6,800 kilometers. This creates a direct link between North America and two central European data hubs. For companies with sites in the US, France or the UK, this route offers one of the most modern transatlantic connections available, with correspondingly low latency.
Amitié reaches a design capacity of up to 400 Tbit/s, spread across 16 fiber pairs using SDM technology. At launch, this made it the highest-capacity transatlantic system ever deployed. The high capacity mainly benefits hyperscalers, financial institutions and companies with data-intensive applications that depend on low latency and high bandwidth between North America and Europe.
The Amitié cable went into service in 2023 and was built by Alcatel Submarine Networks. It is operated by a consortium of Meta, Microsoft, Vodafone, Orange and Aqua Comms, who jointly manage and market capacity on the system. This consortium structure is common on modern transatlantic cables and creates a broad user base, which benefits pricing and availability.
This mainly depends on the landing points you need. Amitié is a good fit if you need connectivity via France or the United Kingdom, MAREA suits a more southerly route via Spain, and Dunant offers a direct, Google-adjacent connection to France. Combining two systems is often the better choice to achieve genuine route diversity and redundancy. SAVECALL advises on the right combination on a vendor-neutral basis.
Genuine redundancy only exists when the chosen cables use different landing points and physically separate routes, for example combining a cable via France or the UK with one via Spain. The landing stations themselves should also be redundantly connected, so that a local outage does not jeopardize the entire connection. SAVECALL plans these concepts independently of any single cable operator, with a focus on actual failover reliability.
Access to capacity on premium cables like Amitié runs through direct wholesale partnerships and IRU or leased capacity agreements with the consortium partners. SAVECALL negotiates these structures directly with the relevant carriers, without detours via reseller chains. Book a free consultation to discuss the right capacity solution for your business.
