Fiber Optic Gulf (FOG)

Overview

Fiber Optic Gulf (FOG) is a regional submarine cable system spanning approximately 1,300 km within the Arabian Gulf. It connects four countries — Bahrain, Kuwait, Qatar, and the United Arab Emirates — forming an intra-Gulf communications corridor among these neighbouring states. The cable entered service in 1998 and remains one of the earlier dedicated submarine links serving this regional cluster.

Route and Landings

In Bahrain, the cable lands at Manama, the capital and principal landing hub for the country. Kuwait is served by a landing at Kuwait City. In Qatar, the cable comes ashore at Doha. The United Arab Emirates landing is located in Dubai. These four landing points span the western and southern shores of the Arabian Gulf, connecting national telecommunications networks across the region.

Ownership and Operators

FOG is owned by a consortium of four telecommunications entities: Bahrain Telecommunications Company (Batelco), Kuwait Ministry of Communications, Ooredoo, and e&. Batelco is Bahrain's principal telecoms operator, while Ooredoo and e& are major regional carriers with presences across the Gulf and broader Middle East and Africa. The involvement of a government ministry — Kuwait's Ministry of Communications — reflects the state-managed telecommunications structure that characterised the region at the time the cable was built.

Technical Profile

The cable system extends 1,300 km in total length, covering the relatively short distances between the Gulf states it serves.

Status and Timeline

FOG became ready for service in 1998, placing it among the earlier submarine cable deployments in the Arabian Gulf corridor. It continues to operate, providing connectivity between its four landing countries.

Regional Context

The Arabian Gulf corridor is now served by a number of long-haul international cable systems that also touch one or more of FOG's landing countries. Systems such as AAE-1 (ready for service 2017), 2Africa (RFS 2024), PEACE Cable (RFS 2022), and SeaMeWe-6 (planned RFS 2026) are intercontinental cables reaching into the region, with total lengths ranging from 21,700 km to 45,000 km. FOG, at 1,300 km, occupies a distinct position as a purely intra-regional system, connecting Gulf states to one another rather than routing traffic to Europe, Asia, or Africa. Measured round-trip latency through FOG averages 95.7 ms over recent testing, with a best recorded value of 22.3 ms.

Strategic Role

FOG provides direct submarine connectivity between Bahrain, Kuwait, Qatar, and the United Arab Emirates, enabling these national networks to exchange traffic over a dedicated Gulf-region cable. Its four landing points cover the principal telecommunications hubs of each participating country, supporting regional data exchange across a compact but economically active maritime corridor. As longer intercontinental cables increasingly land in the same countries, FOG continues to serve the intra-Gulf segment that those systems do not address as their primary purpose.
