Subsea Cables & Internet Infrastructure

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

Funke Opeke, the CEO and founder of MainOne, resigned after selling her firm to Equinix for $320 million. MainOne was one of the first carrier neutral data centre companies in Nigeria and its MDXI facility is almost a must-have for ISPs. MainOne began life as a subsea cable company. At some point Opeke realized that carrier neutral data centers was an attractive business due to high occupancy rates and significant customer switching costs. Moreover, since African data centers often lack good connectivity, the MainOne cable was an excellent complement to any data center facility. MainOne just opened a new facility in Ghana, one of Africa's bright spots in terms of political culture, economic development, and pluralism.

I guess I am too woke for the old telecom guard who have often expressed me to the idea that appointing women as senior managers is '

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 internationl network is old), university research consortiums, governments including their national militaries, NATO, and banks. In particular, hyperscalers are ex

Most subsea cables connect countries, but increasingly we are seeing cables that serve only a single country for a variety of reasons.Either the country is not contiguous like Indonesia or the Philippines or the country is exceptionally large with isolated densely populated cities like Australia. Or it is sparsely settled like Alaska's coast which has no significant land infrastructure like roads or gas pipes to serve as telecom rights of way.  Unitirreno belongs to the former category. This SDM (spatial division multiplexing) 24 fibre pair cable will link Italy's principal territories, the Boot, Sicily, and Sardinia. The design throughput per fibre pair is 20 terabits or 480 terabits per second for the cable. Unitirreno, if built, will be a very high capacity system. Nearly half a petabit.  Here is the company's key sales pitch and commercial justifications: 1. Unitirreno cuts the latency in half between Sicily and Genoa and provides a completely diverse path to the terre
