The West Africa Cable System (WACS) is a 14530km submarine cable system connecting 15 countries, starting from South Africa and ending in London.

The WACS consists of four fibre pairs. It was initially designed with 128 wavelengths per fiber pair, running at 10 Gbps per wavelength, and initial design capacity of 5.12 Tbps. The initial investment of WACS is about US$650million.

WACS Initial Configuration:

  • 4 fibre pairs linking South Africa (SA) to Portugal, with landings in several intermediate countries and an extension Segment to the United Kingdom (UK) and London Point of Presence (Global Switch)
  • 40Gbps wavelengths deployment on the segment between Portugal and United Kingdom from first day of operation.
  • Express fibre pair – interconnect SA, Portugal, and UK through to London PoP  (Global Switch).
  • Semi-express 1 fibre pair – interconnect SA, Nigeria, and UK through to London.
  • Semi-express 2 fibre pair – interconnect SA, Angola, Democratic Repubblic of Congo, Ivory Coast and UK through to London.
  • Omnibus Fibre pair – interconnect SA, Namibia, Democratic Republic of Congo (DRC), Republic of Congo, Cameroon, Nigeria, Togo, Ghana, Côte d’Ivoire, Cape Verde, Canary Islands, Portugal, UK through to London.

WACS system delivers a round trip delay (RTD) of 138.5 ms between Yzerfontein CLS in South Africa to Highbridge CLS in the UK.  

The Yzerfontein CLS in Western Cape Town serves an alternative international submarine gateway othar than the Melkbosstrand CLS in Western Cape Town, South Africa. Telkom South Africa is the landing party and owner of the  Yzerfontein CLS.

WACS Cable System Connectivity

The WACS landing Parties are: Telkom (South Africa), Telecom Namibia (Namibia), Angola cables (Angola), OCPT (Democratic Republic of Congo), Congo Telecom (Congo), Camtel (Cameroon, acquired from MTN Cameroon), MTN (Nigeria), Togo Telecom (Togo), MTN (Ghana), MTN (Ivory Coast), PTC (Cape Verde), Vodacom Group (Canary Islands), Tata Communications (Portugal), Tata Communications (UK), Cable and Wireless (London PoP).

WACS was supplied by ASN, and completed in 2012. The total cost of WACS is approximately US$650 million. It is reported that MTN owns 11% of the initial capacity of the WACS with an investment of US$90 million.

In May 2015, Huawei Marine completed an upgrade of WACS (Upgrade I) using 100Gbps technology, increasing the WACS system design capacity to 14.5Tbit/s.

In Feb 2019, the WACS Upgrade II was completed with Huawei Marine's solutions to support 32*100Gbps from South Africa to Portugal.

MainOne cable system is a 7,000km submarine cable with landing stations in Nigeria, Ghana and Portugal, with reserved branching units Morocco, Canary Islands, Senegal and Ivory Coast.

MainOne cable system is the first private subsea cable along the West African coastline, owned by MainOne Cable Company based in Nigeria. MainOne began the construction project in February 2008 and launched for commercial service in 2010. MainOne cable system was supplied by TE SubCom.

MainOne cable system has been proven to provide capacity of at least 4.96 Tbps.

MainOne cable is able to interconnect with SEACOM and other international cables from Seixal in Portugal, and extend to MainOne PoP at Telehouse North, London, via Tata Communications’ European and Transatlantic networks.

In September 2018, Orange announced to invest in the MainOne cable system, constructing two new branches and stations connecting the MainOne cable to Dakar in Senegal and Abidjan in the Côte d’Ivoire.

 

The Nigeria-Cameroon Submarine Cable System (NCSCS) is a 1100km submarine cable connecting Kribi in Cameroon with Lagos in Nigeria.

The NCSCS cable system consists of two fiber pair, delivering 12.8 Tbps.

The NCSCS cable system forms part of Cameroon’s strategic plan for building a National Broadband Network. The NCSCS cable system is owned and operated by Cameroon Telecommunications Corporation (CAMTEL), the monopoly international and backbone network operator in Cameroon.

CAMTEL partners with MainOne of Nigeria to land the NCSCS cable at Lagos Cable Landing Station which also houses the MainOne Cable System. Through the MainOne Cable System, the NCSCS cable system can be extended to Europe and other coutries in West Africa.

The NCSCS cable system was supplied by Huawei Marine, completed in September 2015.

The Globacom-1 (Glo-1) submarine cable system is a 9800km submarine cable connecting Bude in UK to Lagos in Nigeria and the rest of West Africa. It has landing points in Nigeria, London, Lisbon in Portugal, Accra in Ghana, etc. 

The Glo-1 cable system consists of 2 fibre pairs, with an initial design capacity of 320 (32*STM-64), and upgraded to 2.5Tbps. 

The Glo-1 cable system is owned and operated by Globacom Limited of Nigeria, supplied by ASN with a total cost of about $250 million.

The Glo-1 cable landed in Alfa Beach, Lagos in Nigeria in September 2009, the whole project completed in July 2010. Globacom activated the Glo-1 cable system for service in October 2010.
