The West Africa Cable System (WACS) is a 14530km submarine cable system connecting 15 countries, starting from South Africa and ending in London. WACS was supplied by ASN, and completed in 2012.
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.
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.
- 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)
- 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 for WACS serves an alternative international submarine gateway othar than the Melkbosstrand CLS for SAT-3/WASC, both in Western Cape Town, South Africa.
