Subsea Cables & Internet Infrastructure

Facebook is building a six fibre pair cable directly connecting Taiwan to the the United States with landings at Toucheng, Taiwan, Hermosa Beach, California, and Manchester, California. RFS is 2Q2027. The Hermosa Beach CLS is the well known facility built by RTI Holdings before its bankruptcy. In the submarine cable landing license application, Facebook noted that its motivation was the fact that US-Taiwanese traffic is growing rapidly each year. Due to the 12,000 kilometer length of the cable and the absence of any island landings for power, the design throughput per pair is a relatively low 12.8 Tbps or 76.8 Tbps aggregate initial capacity.  ORCA is an open cable so each fibre pair owner will operate and control its own submarine line terminating equipment with only power being under collective control. Since Facebook is the cable's sole initial owner, the open architecture suggests it will sell capacity on the system to third parties to recoup capital expenditures and share comm...

The planned Bulikala cable connects Google's modular prefabricated Guam CLS to Fiji. It is a part of a grand plan to dramatically increase Pacific subsea throughput and resiliency via a web of island hopping fibre optic cables. These small islands offer diverse network routing. They also offer power, which is the gating factor for throughput over long distances. Bulikala deployment is well underway with a branch recently landing on Tuvalu island, which has only satellite connectivity. The branch is a joint project of Google and the island's PTT. Most Pacific islands are poor due to limited resources, geographic isolation, and poor digital connectivity. They are also threatened by rising water due to global warming. Even the Hawaii island chain is relatively poor with Honolulu being surprisingly run down.  There is a mighty power play at work here. The US government provides aid to these islands sprinkled across the Pacific Ocean for their on-land digital infrastructure while Go...

The planned Bulikala cable connects Google's modular prefabricated Guam CLS to Fiji. The branch is right below Guam on the map at the bottom of this page. It is part of a large scale Google project costing a billion dollars  to dramatically increase Pacific subsea throughput and resiliency via a web of island hopping fibre optic cables. These small islands such as Fiji, Christmas Island, the Marshalls, and Polynesia offer diverse network routing that is particularly valuable in case of a subsea cable segment goes dark. They also offer power, which is the gating factor for throughput over long distances. All power conductors lead to voltage drawdown which limits bandwidth. Boosting power at intermediate points will allow higher transmission rates and lead to better return on the capital invested. The overall plan is to connect Japan, Guam, Hawaii, many islands such as Fiji and French Polynesia to the US in such a way as to increase both throughput via power stops at small islands a...

Transmission Technology: Spatial Division Multiplexing.  Length: 16,026 kilometers. Almost 10,000 US miles. Consortium Members: Google and Facebook. Type of Consortium: Open cable model.  Construction Status: Behind schedule due to permitting delays for Indonesian waters. Fifty-fifty control probably also slowed decision making.  Number of Fibre Pairs: Main trunk has 12. Estimated RFS: 1st or 2nd quarter 2025. Day One Aggregate Throughput: 144 Tbps.  Salient Features: First low latency, direct cable between Singapore and USA with no intermediate breakouts. One Indonesian branching unit. No telecom carrier consortium members. Amazon and Facebook land the cable themselves in Singapore and California.  Google announced  announced the 12 fibre pair SDM Echo project in early 2021 with a planned 2023 launch. However, permitting delays have slowed construction and the project is now expected to be RFS 2025. In addition, it is highly plausible that the 50-5...

Type of Cable System: Spatial Division Multiplexing.  Consortium Members: Amazon, Facebook, Keppel, and Telin. Construction Status: Behind schedule due to permitting delays for Indonesian waters.  Number of Fibre Pairs: Main trunk has 12. Some branches have 6.  Estimated RFS: 1st or 2nd quarter 2025. Day One Aggregate Throughput: 125 Tbps.  Salient Features: First low latency, three digit terabit cable between Singapore and USA.  Bifrost is the name of the burning rainbow bridge that connects Earth to the Realm of the Gods in Norse mythology. This new 12 fibre pair system is a wide lane digital bridge between Southeast Asia and North America (lands in the US and Mexico). It is the first direct single subsea cable solution connecting Singapore, Indonesia, and Philippines to North America that does not touch China or Hong Kong. The key consortium members include Facebook, Telin, Keppel (a new subsea player providing the Singapore landing), and Amazon. Singtel has ...
