The Blue-Raman cable system announced by Google[1] in 2021, and operationalized in 2025[2] is an intercontinental fibre-optic communications cable connecting France to India and also connecting Italy, Greece, Israel, Jordan, Saudi Arabia, Djibouti, and Oman.[1][3] The cable has a Mediterranean submarine segment named Blue, and an eastern submarine segment named Raman (after the famous Indian physicist C. V. Raman) which passes through the Red Sea and Arabian Sea. Both segments fuse on-land at an underground location north of the city of Eilat in southern Israel.[2] By connecting the Mediterranean to the Red Sea overland, the cable avoids passing through Egypt, a country widely regarded as a chokepoint for Internet connectivity.[4][5] The cable consists of 16 fiber pairs implementing google's new space-division multiplexing (SDM) technology, providing a capacity of about 218 Tbps, but able to provide up to 400 Tbps in the future. This makes Blue-Raman the highest capacity cable linking Europe to Asia.
