The Bifrost Cable System is a trans-pacific cable system connecting Singapore, Indonesia, the Philippines, the United State (Guam, Grover Beach, Winema) and Mexico, with its main trunk linking Singapore to the United States over 16,556 km via Indonesia through the Java Sea and Celebes Sea, and total cable length of 20,230 km inclusive of its branches.

Bifrost consortium comprises Meta ( through its direct and wholly owned subsidiary Edge Cable Holdings USA, LLC), PT. Telekomunikasi Indonesia International (Telin), Keppel Telecommunications & Transportation Limited (Keppel T&T) and Amazon (through its indirect, wholly owned subisidiary AMCS LLC).

Keppel T&T, through its wholly owned subsidiary Keppel Midgard Holdings Pte. Ltd. (KMH), participates in the Bifrost consortium as its first direct investment in a subsea cable system, and has acquired a Facilities-Based Operator (FBO) licence issued by the Infocomm Media Development Authority of Singapore (IMDA). The FBO licence allows KMH to own, maintain and operate telecoms infrastructure in Singapore and to provide telecommunications services in connection with the Bifrost cable system. KMH's share of the total project costs as a joint build partner is approximately US$350million (or approximately S$467 million), according to Keppel's announcement.

The whole initial cost of the Bifrost cable system is expected to be approximately US$760million, estimated by SubmarineNetworks.com.

KMH has sold Converge ICT Solutions Inc. (Converge) one fiber pair on the main trunk of the Bifrost cable system on IRU-basis for over US$100 million (around PhP 5 billion). Converge acts as the landing partner to land the Bifrost cable system in Davao, the Philippines, and is granted an IRU on the entire Davao branch.

The Bifrost cable system is supplied by Alcatel Submarine Networks (ASN).

Originally expected to be completed in Q2, 2024, the Bifrost project has been delayed due to bad weather and difficulties to get permits for the cable to land in Indonesia and pass Indonesian waters. And Telin didn't start building the cable landing station in Jakarta for the Bifrost cable system until early June, 2024. 

On January 17, 2025, the US FCC granted the cable landing license for the Bifrost cable system. 

The Bifrost cable system has been ready for service as of October 2, 2025.

Capacity, Segments and Ownership

The Bifrost cable system is designed with 12-fiber-pair SDM technology and 10.4 Tbps/FP, but the capacity for the trunk and branches may be increased up to 15 Tbps if a fiber pair owner decides to regenerate the optical signal in Guam.  

The system capacity of the Bifrost cable system had been upgraded to 260 Tbps, when it was ready for service in October 2025, according to announcement by members of the consortium. 

The Bifrost cable system consists of the following segments

• Main trunk between Tuas, Singapore, Guam (Alupang) and Grover Beach, USA: 16,556 km,12 FPs, 6.13 fiber pairs owned by Meta, 5.52 fiber pairs by Keppel and 0.35 fiber pairs by Telin. 
• Winema branch: 1,552km, 6FPs, soly owned by Keppel. 
• Rosarito branch: 1,147km, 6FPs, soly owned by Meta. 
• Davao branch: 202km, 10FPs,  soly owned by Keppel. 
• Manado branch: 506km, 6FPs,  2 fiber pairs owned by each of Meta, Keppel and Telin.
• Jakarta branch: 268km, 12FPs,  soly owned by Telin.
• Balikpapan branch (stub-BU).

Amazon's roles

As a member of the Biforst consortium, Amazon doesn't have a direct fiber pair ownership (while do a shadow investment on certain Bifrost consortium member), but it controls a cable landing station in Winerma, Oregon, owned by Wave Business Solutions, LLC (d/b/a Astound Business Solutions) (Astound), formerly known as CoastCom in some Oregon coastal areas.

Astound operates the Pacific City cable landing station, owned by Tillamook Lightwave, and a ring backhaul network (Ring I, two 864 cores, low-loss, single-mode fiber cables) linking the undersea cable landing stations in Pacific City to six nearby data centers.

In 2020, Astound built the Hillsboro Data Center Ring II (a 3,456-strand fiber network), together with it Ring I, connecting up to 14 data centers and 7 transpacific submarine cable systems.

In March 2023, Astound announced a project to build a new 100-mile underground fiber route along Highway 6. The project will run from Tillamook to Hillsboro and enable fiber-based Internet service along the highway which currently has limited connectivity. This project is partially funded by AWS’ investment in the Bifrost submarine cable system. Once complete, a portion of the 100-mile fiber route will belong to Tillamook Lightwave, an inter-governmental agency comprised of the Tillamook People’s Utility District, Tillamook County and the Port of Tillamook Bay.
