Grace Hopper is a private transatlantic communications cable that connects the United States of America (New York) with the UK (Bude) and Spain (Bilbao). It was announced by Google in 2020 and scheduled to go live in 2022. [1] The US to UK (Bude) leg went live on 27 September 2022. [2] [3]

History

In July 2020, Google announced that it would be investing in a new private subsea cable — Grace Hopper — its fourth private subsea cable after Curie (which was completed in 2019), [4] Dunant and Equiano. [5] The Grace Hopper cable, which links America with the UK and Spain was named after the American pioneering computer scientist Grace Brewster Murray Hopper, who was known for developing an early compiler that was important in the development of COBOL. Google said it was: "thrilled to honor Grace Hopper’s legacy of innovation by investing in the future of transatlantic communications with a state-of-the-art fiber optic cable". [6]

Google stated that the cable would provide better resilience for its network and marked its first investment in a private subsea cable route to the UK, and its first route to Spain. The cable, which went live in 2022, integrated the new Google Cloud region in Madrid more tightly into Google's global infrastructure. [7] Google's Jayne Stowell also has stated that another motivation for the investment is that many of the existing transatlantic cables are aging and need to be upgraded. “We need to be able to proactively manage the capacity availability, quality, latency, routing, technology and scalability of our network to provide constant, uninterruptible and high quality of network to Google services like Meet, Gmail and Google Cloud,” she said. [8] Telecoms industry analysts have said that the main purpose of Google's subsea cable investments in cables such as Grace Hopper are twofold: to support and control quality of service and to reduce costs. [9]

Specifications

The Grace Hopper cable consists of 16 fiber pairs (32 fibers) of 22 Tbit/s each (352 Tbit/s total) and optical switching that increases its reliability and also enable Google to more easily move traffic around during outages. This technology was developed in co-operation with SubCom, formerly a TE Connectivity company, [10] who built the cable and which also worked with Google on the Dunant and Curie cables. [11]

The cable route comprises a 6,250 km stretch from New York to Widemouth Bay, Cornwall [12] and a 6,300 km route between New York and Bilbao. [13]

Owing to works managed by Telxius, [14] the cable landed in Sopelana (near Bilbao) on 10 September 2021. [15] It later landed near GCHQ Bude on 14 September 2021, with the location chosen as it was "an ideal, nicely protected beach and adjacent to a lot of the terrestrial infrastructure needed". [16]

A transatlantic telecommunications cable is a submarine communications cable connecting one side of the Atlantic Ocean to the other. In the 19th and early 20th centuries, each cable was a single wire. After mid-century, coaxial cable came into use, with amplifiers. Late in the 20th century, all cables installed used optical fiber as well as optical amplifiers, because distances range thousands of kilometers.

A submarine communications cable is a cable laid on the sea bed between land-based stations to carry telecommunication signals across stretches of ocean and sea. The first submarine communications cables laid beginning in the 1850s carried telegraphy traffic, establishing the first instant telecommunications links between continents, such as the first transatlantic telegraph cable which became operational on 16 August 1858.

A cable landing point is the location where a submarine or other underwater cable makes landfall. The term is most often used for the landfall points of submarine telecommunications cables and submarine power cables. The landing will either be direct or via a branch from a main cable using a submarine branching unit. The branch can be several kilometres long.

The West Africa Cable System (WACS) is a submarine communications cable linking South Africa with the United Kingdom along the west coast of Africa that was constructed by Alcatel-Lucent. The cable consists of four fibre pairs and is 14,530 km in length, linking from Yzerfontein in the Western Cape of South Africa to London in the United Kingdom. It has 14 landing points, 12 along the western coast of Africa and 2 in Europe completed on land by a cable termination station in London. The total cost for the cable system is $650 million. WACS was originally known as the Africa West Coast Cable (AWCC) and was planned to branch to South America but this was dropped and the system eventually became the West African Cable System.

Seaborn is the owner and operator of the Seabras-1 "submarine communications cable" between Brazil and the United States. Seabras-1 is fully operational (2017) and provides the first direct route between Sao Paulo, Brazil, and the United States. The system has branching units installed on certain of its fiber pairs that point towards Virginia Beach (US), Miami (US), St. Croix (US), Fortaleza (Brazil), Cape Town, Rio de Janeiro (Brazil), Brazil South. Seaborn's ARBR subsea system is a fully funded 4-fiber pair, 48Tbit/s system. ARBR will directly connect São Paulo, Brazil to Buenos Aires, Argentina. ARBR will connect to Seabras-1 in Seaborn's Praia Grande CLS enabling the most direct, lower latency connection between Argentina and the USA.
