Africa is well served with a number of submarine optical fiber cables that connect the continent to the rest of the world. Most of these cables have been put up in the last 10 years, leading to a ten time growth in African traffic and an annual growth of about 20%. Previously, Africa was connected through expensive satellite links that could not meet the market demands and also drove costs of connection through the roof.
There are 44 active cables and 11 planned cables as of 2017. These cables have a landing in 79 points across 33 countries. As seen in the map below, all but 3 countries that are not landlocked have at least one landing point, with some having multiple nodes. The existence of several cables has helped to improve on redundancy and avoid disruptions caused by cable cuts.
The terrestrial cable network further connects hundreds of other cities, thus making Africa a widely connected continent. Some of the companies with a vast terrestrial cable network include Liquid Telecom Group, and also utilities services companies such as Kenya Power.
