Type of Cable System: Latest Generation Coherent Optics.  Open Cable System: Yes, and possibly the first for Southeast Asia.  Consortium Members: China Telecom, Singtel, Globe Telecom (Philippines), DITO (Philippines), Singtel, Malaysia Telecom, Global Transit, and UNN (Brunei).  Construction Status: On schedule.  Number of Fibre Pairs: 8.  Estimated RFS: 3Q2025. Day One Aggregate Throughput: 144 Tbps.  Salient Features: Three digit terabit cable between Singapore, China, HK, Malaysia, Vietname, and Philippines.  ALC connects Brunei, Hong Kong, Singapore, Philippines, and China. It is a 8 fibre pair system with minimum throughput per pair of 18 terabits per second. Hauwei Marine is building the system which should be ready for service 3Q2025. The project co-leads are Singtel and China Telecom. Hauwei's involvement will deter many foreign carriers from using the cable's transport services, but there are extensive commercial  ties and strong telecom...

The American carrier Zayo has an extensive European wide area network as well as a highly ranked international Internet backbone. Its relatively new subsea Zeus cable links Amsterdam to London via a double armored 96 fibre pair system buried on average between 2 and 3 meters deep. Although Zayo's press releases nowhere states it, any 96 fibre pair cable is undoubtedly unrepeatered just like Scylla and CrossChannel because a repeatered system would probably require more power than possible. Repeatered 96 pair cables do not exist. And like Scylla, Zeus uses ultra-low loss fibre. Probably the Corning SMF28 product. The cable's current throughput is 2.6 petabits per second with the potential to do up to 4 petabits.  One reason both Scylla and Zeus are buried so deep is that the North Sea sediment layers off the  Netherland's coasts are not stable. They move carried by the North Sea's strong wind and sea currents. This necessitates deeper burial to ensure the cable does no...

My best guess is that this extraordinary project goes fully live by the end of the first quarter of 2025. So far only the Kenya/Tanzania/South Africa segments have been activated and it is not clear whether they passing live traffic at this point. For more details, click on  https://www.datacenterdynamics.com/en/news/2africa-cable-set-live-between-south-africa-and-kenya/.  The 2Africa subsea network is based on the principle of carrier neutrality. So in principle cable landing station ownership or operating licenses should not matter in carrier vendor selection. But until practice proves neutrality is being honored, it is best to request capacity from a provider that operates one or both cable landing stations. This advice does not apply to routes that use carrier neutral data centres to house the CLS. So, for example, the Genoa/South Africa path uses GN1 Equinix to house the CLS in Italy and also Teraco data centres. Opportunistic CLS behavior is far less likely when a carrie...

I have teamed up with a nimble African carrier that can quickly deliver  100G waves on the Equiano   cable between carrier neutral data centres for $25K a month or less on 1 year contracts. Both Lisbon/Lagos and Lagos/South Africa routes. Best of all, the provider has a Lagos metro fibre network so it can extend your network on its own fibre from OADC where the Equiano CLS is housed to MDXI Equinix and other data important centres like Rack Centre. This offers significant cost savings over Bharti Airtel and China Mobile International.  We provide 100G wavelength rings between OADC, MDXI, and Rack Centre at prices far less than the customary market offers which vary from $7K to $11K per 100G span. Most Equiano cable capacity providers including t he Chinese and Indian carriers do not own fibre between the Lagos telecom hotels and hence their end-to-end capacity quote will rise by $5K to $10K once wavelength tails are included. Currently no dark fibre is available in Lago...

Seacom went live two days ago and EIG is now being repaired. The repairs revealed that an anchor damaged the cables and hence vindicate my theory that the Rubymar was responsible. Bloomberg quoted me on this issue shortly after the outages started The Houthis hit this ship with a missile and it dropped anchor so the crew could evacuate in life boats. It then drifted over 20 kilometers scrapping the sea floor with its huge anchor which probably weighs five to ten tons. Although Red Sea cables are usually buried, the sea floor is generally soft silt and a heavy anchor will simply sink through the silt and then plow it as the ship drifts. In general, most subsea outages around the world happen on the shallow continental shelf. That means shallow coastal waters where ships damage them via fishing or anchor dropping. Ships drop anchor to achieve a full stop, to stabilize it in transit during bad weather or steady it during an evacuation like the Rubymar.  The real question surrounding ...

The 2Africa is one of the most ambitious and important subsea cable projects ever undertaken. It spans a record 45,000 kilometers or 28,000 US miles. As the map below shows, it extends from Mumbai to Lisbon, London, Genoa, and Marseille and almost completely encircles Africa. 2Africa has a total of 46 landings which enable it to serve 33 countries across Europe, Asia, and Africa. It is unique in having several landings in several countries including 4 in Egypt, 4 in Saudi Arabia, 4 in South Africa, and finally 2 in Congo as well as Kenya, Mozambique, and Spain. A signature theme of the 2Africa project is to improvie network resiliency through physical diversity in the form of multiple, widely separated landings in key countries. For example, the subsea network brings much needed diversity to Nigeria's telecommunications infrastructure with the first CLS outside Lagos in the country's Southeastern region. Many hundreds of kilometers from Lagos.  The 2Africa cable is a spatial di...
