Subsea Cables & Internet Infrastructure

Facebook is deploying the first deep sea 1 Petabit per second fibre optic cable with two optical cores per fibre strand. A core is the optical transmission path in a fiber strand. Standard fiber has one core. The cable will connect North America to Europe and will land in Virginia Beach, and in Bordeaux, France (where the Amitié cable also comes ashore). So it will effectively link Ashburn Equinix to Paris. It is likely Facebook will use the existing cable landing stations serving Marea and Dunant at Virginia Beach. Similarly, in Bordeaux the 1 petabit cable is likely to use the Amitié CLS. Today the highest capacity communication cable in service across the Atlantic or any ocean for that matter is the half petabit Anjana, another META project. It has 24 fibre pairs operating at 20 Tbps per pair. Shannon's law tells us that a fibre pair operating at 20 Tbps is pretty close to full spectral efficiency.  Hence boosting per pair output is a dead end if the goal is to rai...

As most of you know, Kenya is one of East Africa's two subsea hubs (Djibouti is the other). The Communication Authority of Kenya requires cable operators to report total lit capacity on a quarterly basis. The chart below shows the market is tight. Only Seacom was able via a large upgrade to increase lit capacity. It appears to me the local cables are maxed out. Seacom itself is getting old. It went live in July 2009. Hence it is approaching 20 years. So it is likely unless Ciena whips up more modulation magic that Seacom is at its lifetime max capacity. Note that 2Africa data has not been integrated into the official statistics, but it is important to note that international traffic is largely between Kenya and Europe, not Kenya and South Africa. Since 2Africa remains incomplete in the Red Sea, it may not affect total lit bandwidth that much. We know the local market is tight not just from the lack of growth in lit capacity, but also the high prices that 100G waves com...

Apricot is one of the most exciting Southeastern Asian cable projects to be RFS next year. In fact, it is the first subsea network to be truly physically diverse from the South China Sea. The 12 fibre pair main trunk's end points are Singapore and Tokyo, but the path completely bypasses the South China Sea by detouring through Indonesia and up the Philippines' East Coast. This increases latency, but makes Apricot the natural complement for any cable system like ADC or SJC2 that goes through the South China Sea. Obviously the latency is higher than the usual suspects, but most buyers need resilient networks to keep their jobs. Apricot lands in Singapore, Indonesia, the Philippines, Taiwan, Guam, and Japan. The cable system has military value as it links Taiwan to the Guam, the latter being the US military command center for the Western Pacific. Its routing around the South China Sea also makes it less vulnerable to sabotage. Design capacity was originally intended to be 211 Tbps...

The standard description is that 2Africa is a 16 fibre pair cable with 180 Tbps throughput. It comes right off the 2Africa website. That public figure is a bit misleading. Only the Mediterranean and Red Sea segments have 16 pairs. The all-important West Coast segment has 8. Now these fibre pairs should individually be capable of 20 Tbps or slightly more. So West Coast transmission capacity probably does total 180 Tbps. Indeed, the Mediterranean segment could easily exceed 320 Tbps. And the same for the yet unfinished Red Sea segment. Design Capacity By Segment A. Mediterranean Sea: 16. B. Red Sea: 16. Not finished due to hostilities. C. Red/East Africa: 7. D. Red Sea/India: 9. E. West Coast: 8.

Blue Origin is a Jeff Bezos' startup providing space services to NASA and other clients. Those services include cargo delivery, rocket engines, lunar landing vehicles, and under development, a commercial space station. Blue Origin's New Glenn rocket carries as much cargo as SpaceX' Starship and successfully launched a NASA probe in late 2025. The first stage is reusable.  New Glenn's success has encouraged Blue Origin to develop new satellite constellations. The company announced yesterday a hybrid network of 5,280 LEO and 128 MEO satellites called Terawave that will use dual free space lasers and radio frequencies to communicate with the Earth. Radio frequency will provide a minimum committed bit rate of 144 Gibabits per second, many magnitudes greater than what Starlink offers, with free space lasers boosting the throughput by 6 terabits in ideal weather conditions. Dual connectivity is not a new idea. Low latency financial trading platforms have been using microwave ...

Both Indigo West and SJC are experiencing outages. I suggest trying ADC as non-Chinese capacity is available on favorable terms for three year contracts. TATA and TELIN are good choices. I can help with either of them. For Chinese capacity, I believe China Unicom has some very aggressive deals as well. Contact Omer Tariq in London or Georgio Garguillo in Milano.  SJC went live in 2013. Its design capacity is 28 Tbps and the cable has six fibre pairs. It connects mainland China, Hong Kong, Japan, the Philippines, Singapore, Brunei, and Thailand. Both Sub.com and NEC built the system. The SJC consortium is large and includes China Telecom, China Mobile International, KDDI, Taiwan PTT, Singtel, TOT, Google, and a subsidiary of the Brunei PTT. 

A good Tech Capital article on the new wave of American Tech Giant cables in Asia:  https://thetechcapital.com/subsea-shake-up-how-new-cables-are-wiring-southeast-asias-ai-era/. My list of the most important new cables: 1. Apricot is a 12 fibre pair Southeast Asian cable with throughput of 290 Terabits. It bypasses China, Hong Kong, and the South China Sea in a clear signal to the Chinese government to get lost. Google and META are consortium members. 2. Echo is a 12 fibre pair Pacific cable directly linking Singapore to the United States. It has 144 Tbps throughput. Google and Facebook are equal partners in the project. The lower throughput reflects the 20,000 kilometer length of the cable. Same holds true for Bifrost. 3. Bifrost is the sister cable linking Singapore to the US. Its digital horse power is 180 Tbps. 4. Waterworth is a 480 Tbps behemoth with 24 fibre pairs. We still don't know the exact landing points in Asia. It will land on both the West and East coasts ...

- 2Africa is much more expensive than Equiano. The 2Africa 100G pricing is $25K and above excluding tails for Lisbon to Lagos. In contrast, Equiano 100G pricing is below $20K now. Similarly, Equiano 10G pricing gravitates around $5K versus $10K on the same route for 2Africa.  The reason for this disparity is that the 144 Tbps Equiano cable primarily serves South Africa, Portugal, and Nigeria. In contrast, the 180 Tbps 2Africa network serves over 30 countries and Facebook kept 4 of the 16 pairs for itself. Note that the 2Africa map does not include the Pearls extension of 2Africa to the Persian Gulf, Pakistan, and Mumbai.  Another sign of the impending capacity crunch is the unwillingness of 2Africa consortium members to sell IRUs. An IRU is a long term capacity sale ranging typically dffrom 10 years to life of system. Carriers will not sell IRUs if they expect future capacity shortages or think they are likely. Many of these carriers have transit backbones that they must keep ...

The eight fibre pair ADC system went live in November of last year. Its design capacity is slightly above 160 Tbps. Consortium members and large capacity owners include China Telecom, China Unicom, PLDT (the Philippine incumbent), Singtel, Softbank, TATA, and Vietel. TATA owns a fibre pair marketed under its own brand, TGN-IA2. NEC built the Asia Direct Cable. ADC 100G pricing for the Singapore to Tokyo route varies from $13.5K to $18.5K MRC on three year contracts. If you wish to avoid Chinese carriers, yet enjoy competitive pricing, TATA is a good choice. By a Chinese carrier I mean a network licensed to operate in mainland China and hence subject to its national security laws. These laws dictate that Chinese operators must cooperate with Chinese national security agencies. That's a big problem. In contrast, as just one example, Apple refused to cooperate with the FBI on unlocking a phone in an investigation. So there is a clear difference between China and the Wes...

The conflict between China and the West is exacerbating bandwidth shortages on key routes like Marseille to Singapore. AAE1 is maxed out just like SWM5. Both will be upgraded this year, but I believe all the incremental capacity will be snatched up even before upgrades are finished and the capacity delivered to customers. Furthermore, China Unicom is the lead AAE1 consortium member with China Mobile also selling capacity on the system. Avoiding carriers incorporated in China makes intercontinental capacity shopping is an excruciating exercise. I've been seeking Express AAE1 100G for almost a year for clients for whom China is a red line. Bandwidth sourcing has become a marathon. 😄 In light of this, I recommend buyers consider Peace despite the fact that it is a Chinese financed project. Encryption does work. It will not protect the IP overhead, which include the IP addresses, but the data payload itself will remain safe. Moreover, there are Peace providers such as PCCW or TELIN t...
