Facebook's New Pacific Cable ORCA

Image
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...

Microsoft's Second Irish Sea Cable: Tuskar

Image
Microsoft has filed an application to do a geophysical survey for a new subsea fibre optic cable connecting Ireland to the UK. The Irish Maritime authority has blessed the application. Tuskar is the name of an Irish lighthouse located on a rock in the Irish Sea. It was the first Irish facility to be powered by electricity. The cable's tentative design is to land at Kilmore Quay on the Irish side with the British landing at Newgale in Wales. Again, I expect a 96 fibre pair unrepeated cable system.  Some of my readers have expressed skepticism that Microsoft would be building its own cable when there have been several carrier builds across the Irish Sea in the last five years. EUNetwork's Rockabill unrepeatered cable has 96 fibre pairs; it went live in 2019. Aquacomms CeltixConnect-2 cable is an unrepeatered system that went live March 2022. And that's not at all. Zayo has 24 fibre pairs on the power cable Interconnector East-West.  But here's the thing. I don't think...

Microsoft Planning Its First Irish Sea Cables - The SOBR2 Project

Image
Microsoft has applied for several maritime usage licenses to do ship geophysical surveys of proposed routes for new subsea cables connecting Ireland to the UK. Its SOBR2 cable will connect Ireland to Wales as opposed to the usual Cornwall landings. It will apparently land at Malahide Beach or Portmarnock on the Irish side. Another possibility is a branch with a landing at both Malahide and Portmarnock. Details are very sparse on the cable itself. My educated guess would be a 96 pair unrepeatered cable because it minimizes capex while maximizing bandwidth punch with such systems easily pushing a couple petabits per second. The site survey will focus on the top three meters of the sea floor. It will take samples to ascertain the texture and composition of material with an eye towards a deep burial of the cable itself if possible. The samples will help determine not only burial depth but also how well armoured the cable will be. The Irish Sea is notorious for fibre cuts due to trawler fis...

Houthi Rebels Endangering Subsea Projects Including SWM6 & 2Africa

Image
As you know, the Rubymar dragged its anchor for 31 kilometers after its crew abandoned it last spring. In so doing it severed the AAE1, Seacom/TGN, and Eassy cables. After several months stalemate, the Houthi rebels gave the consortiums permission to repair them as long as it was done in a low key fashion. The fact that AAE1 lands in Yemen gave the Houthis political cover with their supporters. But the reality is that since then the Houthis have refused to agree to refrain from targeting cable ships laying new systems like 2Africa, Blue-Raman, and SWM6. This is why these projects are currently well behind schedule. There is no way to complete them in the near future as designed. Probably the only way forward right now would be build terrestrially along side the Red Sea through Saudi Arabia. In other words, bypass that part of the Red Sea adjacnet to Yemen. For example, Oman could hand off Blue-Raman traffic to Saudi Arabia which could take it across the desert and essentially bypass th...

The Most Important Subsea Cables Going Live In 2025: Firmina

Image
 Firmina is a spatial division multiplexing 16 fibre pair cable with initial design capacity of 320 Tbps. It is named after a Brazilian abolitionist, Maria Firmina dos Reis, who was Brazil's first novelist. Google is the owner. Telxius has acquired a fibre pair on the system as part of a complex deal that involves providing landing and back haul in Brazil. Right now Google is selling fibre pair and spectrum capacity to recoup its capex. Cirion Technologies has also purchased a pair. Stonepeak Investments, an  infrastructure investor, purchased Lumen's South American assets which operate today as Cirion. Firmina is substantially complete, but no RFS announcement so far.  Distinguishing Features: 1. It is possible to power the entire cable from either the US or Brazilian landing stations in case the other CLS experiences a black out.  2. Firmina is the third South American hyperscaler subsea cable. Google is the owner of all three.  3. Firmina is the first spatial...

The Google/US Government Pacific Subsea Cable Power Play

Image
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...

Update on the Baltic Subsea Cable Outages

Image
Both cables has been repaired, namely the one connecting Lithuania to Sweden and the C-Lion system as well. The emerging consensus within the European subsea cable community is that the German, Finnish, and Estonian authorities are wrong in claiming sabotage. Anchor dragging is a very crude form of sabotage and in this case the Chinese ship Li Peng crossed 13 cables and only damaged two. Secondly, a key requirement of sabotage is a safe get away. A heavy, slow cargo ship is not a good getaway car. Furthermore, the European press got it wrong when it claimed the ship captain is Russian. It is a Chinese ship with a Chinese captain. I have written an article explaining why the sabotage accusations are so flimsy in my opinion: https://subseacables.blogspot.com/2024/11/american-officials-say-no-sabotage-in.html. The ship dragged its anchor probably to steady itself in bad weather and turned off the transponder because the captain knew what it was doing was irresponsible. I suspect the l...

C-Lion Cable Down

Image
C-Lion Cable Down In Baltic Sea C-Lion is an 8 fibre pair high capacity linear cable that went live in 2016. Transmission rate is 144 Tbps. The cable connects Helsinki data centers to Frankfurt via a cable traversing the Baltic Sea. C-Lion lands at Rostock, Germany, and at Helsinki. The Finnish government financed, owns, and operates the subsea network in the national interest. One goal of the project was to reduce network dependence on third country transit via Sweden or the Baltics. Another was to provide enough capacity to grow the Finnish data center market.  Finland offers many advantages for large data centers. Its cool climate dramatically lowers cooling costs as well as extending server life spans. There is also attractively priced, reliable, and abundant power in the form of hydro, nuclear, and wind. I think the large Google data center in Hamina, Finland opened the government's eyes to the economic potential that subsea capacity unlocks. Indeed, Google announced just a fe...

Firmina Cable, Google, & Cirion

Image
Google's Firmina cable is a 16 fibre pair spatial division multiplexing cable that connects its Myrtle Beach CLS in South Carolina to Uruguay, Brazil, and Argentina. Firmina was one of Brazil's first notable writers and novelists. The cable is on the verge of RFS with the wet segments done and the focus on securing back haul, equipment installation, and testing. Design capacity is 240 Tbps. The cable is open. This means each fibre pair or spectrum owner selects the Layer 1 technology vendor such as Ciena or Infinera. Hence Firmina is technology agnostic. This reflects the fact that subsea optical amplifiers are compatible with all DWDM manufacturers and hence there is no compelling reason for capacity owners to chose the same terminal equipment. The main reason for doing so was the consortium model where a single operating entity was created to manage the physical assets on behalf of the members. But this model lead to conservative, status quo decision making. Google and the ot...

New Regional Subsea Cable: Egypt/Saudi Arabia.

Image
Telecom Egypt and Mobily are cooperating on a new subsea cable connecting Egypt and Saudi Arabia. Telecom Egypt is a PTT whereas Mobily is a competitive Saudi Arabian mobile operator. Few details regarding the project are available. Mobily is financing the project whereas TE is the cable landing partner. This project reflects a broad trend where competitive mobile providers are becoming more involved in connecting Middle Eastern countries both to reduce their own costs and also create strategic alliances. In fact, Mobily is following the same game plan as the much larger Vodafone and Bharti Airtel. As mobile voice and data traffic becomes increasingly international, mobile providers acquire more international capacity and often the wholesale market. Typically, they buy more than they need themselves because bigger purchases lower per bit costs. Then they sell the excess capacity in the wholesale market. This is how Bharti entered the wholesale telecom market. Most likely this new cabl...

An Emerging Subsea Telecom Hub: Genoa

Image
Marseille with its 16 cables tightly squeezed into reserved sea lanes and landing facilities violates the cardinal rule of network diversity. It's highly efficient, but resiliency requires physical diversity. In general, resiliency costs money because it requires not relying solely on the big interconnection points. Indeed, there is a fundamental conflict between minimizing network costs and maximizing performance. This has led consortiums and the digital titans to seek other landing points to reduce Marseille's importance. Besides being a long distance from Marseille and on a separate power grid, Genoa offers lower latency access to Italy's eyeballs as well as Switzerland, Germany, Austria, Scandinavia, and Eastern Europe. The city offers clear advantages for a landing spot.  On the down side, landing cables at Genoa is more challenging than Marseille because cables must traverse more shallow waters to reach it. Cables must be threaded between Sardinia, Corsica, and Italy....

Breaking Story: Facebook Building Subsea Cable That Will Encompass The World

Image
Several sources have whispered in my ear that META is planning a new 16 fibre pair cable that will encompass the world going from the US East Coast to the US West Coast via the Atlantic, Indian Ocean, and the Pacific. The most ambitious subsea project ever undertaken. I do not know the exact routing. I know that the cable will launch from the American East Coast and will go down the West African Coast to South Africa and then head straight to Mumbai. It is not clear if Europe will be online or not. From Mumbai it will head straight to Australia and then up to the US West Coast. I speculate that there may be branching units to Singapore, Malaysia, and Indonesia. But the basic routing is US/South Africa/India/Australia/US. What is not clear is if there will be branching units to add more countries to the cable.  This semi-secret cable reflects META's desire for network resiliency given the four month Red Sea down time that AAE-1 and other subsea cables suffered during the first half ...

The Atlantic: Aquacoms

Image
I n 2005 there were 7 high c apacity Trans- Atl antic subsea fibre optic networks connecting North  Americ a to Europe. Flag had two cables, Hibernia  Atl antic two as well, Level3 owned the Yellow cable, Global Crossing had  AC1, the PTTs owned TAT-14,  and  Apollo h ad two. In most cases the cables landed in either Ireland or the UK with most traffic destined for downtown London telecom hotels like the various partitions of Telehouse London (East & North at that time). London was Europe's key telecom hub. The other two important hubs were Frankfurt and  Amsterd am.  At the time Teli a Carrier was buying 10G waves 60 Hudson to Telehouse East for $38K a month. But that did not last long.  There was chronic excess capacity due to zombie subsea cables. In most industries if rates of return are depressed, firms exit the industry with their assets sold to be used in other sectors. Consequently, the in...

Buyer Pricing Guidance: The Atlantic

Image
The Atlantic at the 100G level ranges from $4K to $6K MRC. The cables deployed at or around the time of the New Millenium vary from $3,800 to $5K. Generally, new cables like Marea and Dunant command a premium because they directly connect Ashburn Equinix to Continental Euroipe with both Ashburn Equinix and at least two Paris Equinix facilities onünet. Both bypass Ireland and the British isles. So expect to pay in the $5K to $6K range on 2 or 3 year terms. And yes, you should pay the premium because Marea, Dunant, Anjana, and Nuveem all dramatically improve resiliency. The NYC/London cooridor is congested with most UK landings in Cornwall at Bude. Furthermore, UK surveillance of undersea cables is well known.  Any saavy buyer should be riding both NYC/London cables and also cables like Dunant and Marea that directly link Ashburn Equinix to the European continent. This physical diversity is not a luxury; it's essential. A special mention goes to EXA Express for NYC/London which is a ...

Today's Interview With Eastern Light - New Nordic Undersea Dark Fibre Ring

Image
Eastern Light is building a hybrid subsea-terrestrial dark fibre ring connecting Sweden, Finland, the Baltics, Germany, Denmark, and Norway. This morning I interviewed their sales director to better understand this ambitious project. The fibre pair count is 3x 144 pairs or 432 in total. No lit optical circuits or wavelengths will be sold. Instead, customers will be leasing or purchasing via IRU fibre pairs that they will light using their own equipment. There are ILAs for the subsea spans located   on islands, but the short distances make them an option, not a necessity. However, some customers will undoubtedly prefer buying less and optically amplifying to juice the transmission rates. Because it is a dark fibre network, the customer base will be predominantly hyperscalers, big carriers including the incumbents (Telia's international network is old), university research consortiums, governments including their national militaries, NATO, and banks. In particular, hyperscalers are e...

Subsea Cable News - SMW6, Mist, 2Africa

Image
Mist delayed due to hard rock at Indian CLS. Construction teams find the rock between the CLS and the beach manhole is too hard for directional drilling. A new path around the rock is required.  SMW6 will only go live in 2026.  APG down 12 months since start of 2023. Cursed cable.  2Africa struggling due to delays in the Northeastern Africa quadrant.  Bifrost behind schedule. Ground breaking on the Jakarta CLS was just in June and just a few days ago for the second CLS. Figure late 2025.  Peace cable is cheap in part because 40% of potential customers will not use it because Chinese companies built and equipped it. . Equiano 10G prices are relatively high because many carriers only offering 100G. There is a dearth of 10G providers.  Anjana and Firmina on schedule because neither cable is a consortium. Consortiums are too slow and make mediocre decisions.  Bay of Bengal Gateway capacity is low and prices rising.  2Africa 100G pr...

Firmina: The Other Atlantic Leviathan

Image
 Like Anjana , Firmina is a content provider project. Google is the owner and bank for the 16 fibre pair (main trunk) spatial division multiplexing cable. The subsea network will connect the Myrtle Beach, South Carolina cable landing station to a Telxius CLS in Praia Grande (near Sao Paulo) and two other landings in Uruguay and Argentina. I think Google picked South Carolina because it represents a good latency compromise as some of the traffic is destined for Miami and some for Ashburn Equinix. It also improves the Google network's overall resiliency and its cloud infrastructure. I have noticed that Google has a tendency to run its fibre pairs at lower transmission speeds than Facebook. The design transmission rate for this system is 15 Tbps per pair whereas Facebook's Anjana is 20 terabits. So Firmina's design aggregate transmission rate day one is 240 Tbps. A quarter of a petabit.  Telxius has purchased a fibre pair on life-of-system IRU. I expect others will be looking ...

Asia Direct Cable (ADC) Update

Image
The wholesale telecom community eagerly anticipates the lighting of the ADC system. This 8 fibre pair cable has an intitial design capacity of 180 Tbps. It will serve China, Japan, Singapore, Philippines, Thailand, and Vietnam. NEC is building the cable. Consortium members include China Unicom, China Telecom, Singtel, Softbank, Tata, and one of the two Vietnam operator incumbents.  My sources tell me the current RFS estimate is January, 2025.  Good Singapore/Tokyo pricing available. Figure as low as $15K per monthon long term contracts.  SJC and SJC2 are relatively good complements as they do not share cable landing stations with ADC.  HK-SG 35.5 ms RTD. SG-TOKYO 66.5 ms RTD.  TOKYO-HK 44.5 ms RTD.  Singapore Landing Station: Tuas. Tokyo Landing Station: Maruyama. 

SEA-H2X: The Mystery Player Among Southeast Asian Subsea Cables

Image
SEA-H2X: A Mystery Player Among Subsea Cables This cable is very under the radar. Very few industry insiders ever mention it. Yet, it is not an insignificant project. The main 8 fibre pair trunk directly connects Singapore and Hong Kong. It uses branching units to extend the cable to Malaysia, Thailand, Philippines, and a free trade Chinese port city known as Hainan. Hauwei Marine built it with advanced branching units that include optical switching as well as flexible power distribution. The cable's design capacity is 180 Tbps. At 20 Tbps a pair, I suspect there is upside throughput potential.  Interestingly enough, it is an open cable system so each consortium member selects and buys their own submarine line termination gear which I assume includes the DWDM kit. This helps to some extent alleviate the concern that Chinese security agencies have compromised the system. But there are other ways of eavesdropping other than infiltrating the terminal gear even though that is the best ...
