Technology & capacity
Grace Hopper uses state-of-the-art fiber optic technology and achieves a capacity of up to 340 Tbit/s, making it one of the most powerful transatlantic cables. Essentially, these are the technological features:
- SDM (Space Division Multiplexing): The use of 16 fiber pairs enables a significantly higher capacity than older cable systems with fewer fiber pairs.
- Open Cable Design: Grace Hopper is designed as an open cable system that enables flexible usage models for consortium partners.
- The latest generation of fiber optic technology for minimal signal loss and stable transmission quality along the entire transatlantic route.

Frequently asked questions about the Grace Hopper cable
Grace Hopper connects Bellport, New York, with Bude in the United Kingdom and Bilbao in Spain. This makes it the only system on a single route offering direct access to both the UK and Iberian markets. For companies with sites in the US, the UK or Spain, Grace Hopper is one of the most modern transatlantic connections available.
Grace Hopper reaches a design capacity of up to 340 Tbit/s, spread across 16 fiber pairs using SDM technology. This makes it one of the highest-capacity transatlantic cables in the world. The high capacity primarily benefits Google’s own cloud and data center services, but is also accessible to third parties through wholesale partnerships.
Grace Hopper entered service in 2022 and was built by SubCom. Unlike many other transatlantic cables, it does not belong to a consortium but is owned exclusively by Google. The company primarily uses Grace Hopper to strengthen its own global network infrastructure and for cloud services such as Google Cloud, Gmail and Meet.
This mainly depends on the landing points you need and the ownership model you prefer. Grace Hopper is a good fit if you need both the UK and Spain connected via a single route, Dunant offers a direct connection to France, and MAREA provides the established route via Spain with a classic carrier consortium. Combining several systems is often the better choice to ensure genuine route diversity. SAVECALL advises on the right combination on a vendor-neutral basis.
Genuine redundancy only exists when the chosen cables use different landing points, operators and physically separate routes, for example combining a private hyperscaler cable like Grace Hopper with a consortium cable like Amitié or MAREA. Relying solely on a single ownership model adds an extra concentration risk. SAVECALL plans these concepts independently of any single cable operator, with a focus on actual failover reliability.
Access to capacity on privately operated hyperscaler cables like Grace Hopper runs through direct wholesale partnerships and IRU or leased capacity agreements with Google or its distribution partners. SAVECALL negotiates these structures directly, without detours via reseller chains. Book a free consultation to discuss the right capacity solution for your business.
