Where are submarine cables connected

African coast to Europe (cable system) - Africa Coast to Europe (cable system)

Fiber optic submarine cable system

Africa Coast to Europe ( ACE ) is a fiber optic submarine cable system for 24 countries on the west coast of Africa and Europe, managed by a consortium of 19 members.

The ACE cable connects more than 400 million people, either directly for coastal countries or via land links for landlocked countries such as Mali and Niger. ACE is also the first international submarine cable to land in Equatorial Guinea, Gambia, Guinea, Liberia, Mauritania, São Tomé, Príncipe and Sierra Leone.

Arrangements are being made to allow other operators to arrive in countries along the ACE cable route. Guinea-Bissau is the next country to be hooked up on the submarine cable.

The ACE consortium consists of telecom operators and member countries who have invested $ 700 million in the overall project, sometimes with financial support from the World Bank. The consortium agreement was signed on June 5, 2010 and on December 15, 2012 this 17,000 km long cable was put into operation for the first time. The official inauguration ceremony took place on December 19, 2012 in Banjul, Gambia.

The 4 to 5 cm diameter cable has a potential capacity of 12.8 Tbit / s and runs about 6,000 m below sea level.

It was manufactured by Alcatel Submarine Networks (ASN) and relocated by ASN and Orange Marine ships.

Segment 3

Segment 4 (under construction)

Technical characteristics

This 17,000-kilometer cable is the only one that connects 24 West African and European countries. The members of the ACE consortium are organized according to a global access concept: Several investors in one landing station. ACE sea routes have a low error history and time-reliable technology. The cable can use a newer transponder technology.

Technical characteristics are as follows:

  • PoP to PoP connection for access to major cities in Europe and Africa (Paris , Lisbon , Cape Town)
  • 100G technology proof
  • Design capacity = 12.8 terabytes per second
  • Lighting capacity = 1.6 terabytes per second
  • Initial capacity 200 Gbit / s in segment 1, 160 Gbit / s in segment 2 and 3
  • Maximum capacity of 12.8 Tbps in design
  • Longest DLS = 4400 kilometers (Penmarch - Dakar)
  • Low latency (express and bus fibers)
  • Uses wavelength division multiplexing (the most advanced for submarine cables)

The online search has not returned any significant failures due to cable damage since 2012 until March 30, 2019.
