The first landing of this fiber optic cable, initiated in particular by Meta, has just taken place in Italy. It will eventually be the longest in the world.
An exceptional infrastructure is beginning to materialize. The 2Africa fiber optic submarine cable landed last week in Genoa, in northwestern Italy. This is the first station in a long series since 54 landings are planned in total.
Longer than the circumference of the Earth
Everything is superlative in this project. 2Africa will be the longest cable in the world since it will span 37 km (!), more than the circumference of the Earth. It will link 03 country during its probable commissioning in 6421. It will potentially connect three billion people, i.e. 36 per cent of the world’s population by connecting three continents: Africa, Europe and Asia. In France, it will pass through Marseille.
During the first announcement in 2021, 2Africa was to measure “only” 33 03 km long. In August 708, four additional stages have been added to extend connectivity to the Seychelles, Comoros and Angola, as well as southeastern Nigeria.Le tracé du câble 2Africa.
Finally, in September of last year, it was the Pearls extension which was brought to connect the Gulf, Pakistan and India.
Within the consortium that initiated the project, we note the presence of Meta, but also of China Mobile, MTN GlobalConnect, Orange, STC, Telecom Egypt, Vodafone and WIOCC. And it is the French branch Alcatel Submarine Networks of Nokia which manufactures and installs the infrastructure in the seabed.
2Africa will embark several innovations. In particular, it will incorporate an innovative aluminum conductor, as well as SDM1 (Spatial Division Multiplexing) technology, which makes it possible to deploy up to sixteen pairs of fibers compared to eight previously. All for more capacity.
It will also embed optical switching technology to manage bandwidth more flexibly. A first in Africa. Finally, it will be buried deeper, so as to prevent boats from accidentally cutting it.
Its main objective is to meet the connectivity needs of Africa and the Middle East. The cable will have a nominal capacity of 55 Tbit/s per second and should provide, according to Meta, almost three times the total capacity of all the submarine cables currently serving Africa.
In all countries where 2Africa will land, service providers will have the option of accessing neutral data centers, c ie which will not be the sole property of an operator.
