The Oman Australia Cable (OAC) is a 9,800 km fibre-optic submarine communications cable that entered service in September 2022,[1] linking Oman and Australia via the Cocos (Keeling) Islands. The cable consists of three fibre pairs and had an initial design capacity of 39 terabits per second.[2]

OAC is owned and operated by SUBCO, with Omantel as the landing partner in Oman, and Equinix[3] providing the landing stations in Perth and Muscat.

History

The cable was announced by SUBCO in 2020, with a target completion date in 2021.[4] Manufacturing of the cable was completed by SubCom in January 2021,[5] with the SubCom cable ships CS Dependable and CS Reliance[6] being used for the installation works. The cable made landfall in Perth on 22 July 2021,[7] with landing station infrastructure in the Cocos (Keeling) Islands also being manufactured and installed during 2021.[8][9] Final landing of the cable in Barka, Oman occurred on 28 April 2022.[10]

The cable went live during September 2022,[11] and was officially switched on by Anthony Albanese, the Prime Minister of Australia, during a ceremony in Perth on 24 October 2022.[12]

In March 2023, SUBCO announced plans to extend the cable with the installation of a diverse 1,200km spur that would land at Salalah, Oman,[13] which is expected to be completed by the end of 2024.

In October 2023, the cable was upgraded by Ciena from its original design of 39 Tbit/s to 48 Tbit/s of lit capacity.[2]

Routes

The Oman Australia Cable has been interconnected with the INDIGO Central and INDIGO West optical fibre cables at the Australian landing site in Perth.[1] SUBCO and Omantel are expected to extend the reach of the cable with connections from Muscat to London, Milan and Marseille.[14] The cable also includes additional branching units for future spurs that may link to Salalah, Oman and Djibouti City, Djibouti.[15]

The cable is notable for providing a diverse international route from Perth, and a lower-latency path between Australia and Europe, the Middle East and Africa.[10] Competing cables such as the Australia Singapore Cable, INDIGO West and SEA-ME-WE 3 all traverse a similar path via the Sunda Strait to Singapore, whereas OAC traverses the Indian Ocean to the south-western coast of Asia.[11]

The cable route is also noted as being similar to another proposed cable known as Australia West Express, which was first announced in May 2015[16] but was unable to obtain the investment required for construction and was ultimately cancelled.[17]

Diego Garcia Spur

During the laying of the cable,

branching unit and spur may have been installed to provide connectivity to the atoll.[18]

On 6 July 2023, the existence of the Diego Garcia spur was publicly confirmed by the United States Pacific Fleet as part of a Reuters investigation into SubCom.[17] The article went on to state that the cable was previously announced to sailors on Diego Garcia by Captain Richard Payne, the commander of Diego Garcia at the time, during a talkback radio show on 9 February 2022, and that The Pentagon had paid for "around a third of the entire cable on the condition that it include a splice connecting its commercial trunk to Diego Garcia".
