The South Atlantic Inter Link (SAIL) (formerly referred to as Cameroon-Brazil Cable System, CBCS)[2] is a submarine communications cable in the South Atlantic Ocean linking Kribi, Cameroon with Fortaleza, Brazil.
SAIL submarine cable project was jointly invested and constructed by China Unicom and Camtel. The cable landing points are operated by Camtel in Kribi and by China Unicom Brazil in Fortaleza. China Unicom provided project management and business operation support, while the engineering construction was contracted from Huawei Marine Networks. The whole project lasted for 14 months and was completed in August 2018.[1]
The cable measures approximately 6,000 km in length and contain four optical fibre pairs, each capable of transmitting 100 wavelengths with a bandwidth of 100 Gbit/s (gigabits per second), for a design capacity of 32 Tbit/s (terabits per second).[3][4][5] The project was financed through the Concessional Loan and Preferential Export Buyer’s Credit of China Exim Bank.[1]
SAIL is an intercontinental submarine cable across the South Atlantic sea area, connecting the continent of Africa and South America establishing new Internet channels for Africa-South America, Africa-North America and South America-Europe.

Rigging comprises the system of ropes, cables and chains, which support and control a sailing ship or sail boat's masts and sails. Standing rigging is the fixed rigging that supports masts including shrouds and stays. Running rigging is rigging which adjusts the position of the vessel's sails and spars including halyards, braces, sheets and vangs.
Andrew Smith Hallidie (March 16, 1836 – April 24, 1900) was an American entrepreneur who was the promoter of the Clay Street Hill Railroad in San Francisco. This was the world's first practical cable car system, and Hallidie is often therefore regarded as the inventor of the cable car and father of the present day San Francisco cable car system, although both claims are open to dispute. He also introduced the manufacture of wire rope to California, and at an early age was a prolific builder of bridges in the Californian interior.
WASACE was a planned system of submarine communications cables consisting of four sections with a total length of 29,000 km linking four continents. Original proposal: WASACE North, from Spain to the United States WASACE South, from Brazil to Nigeria WASACE America, from Brazil to North America. WASACE Africa, from Nigeria via Angola to South Africa WASACE Africa would potentially be the fifth cable running from South Africa to Nigeria. WASACE South would be the third cable linking Latin America to Africa, and would compete on a direct route from Africa to Brazil with the planned South Atlantic Express (SAEx) cable. The first cable from Latin America to Africa is the Atlantis-2 cable which runs from Brazil to Portugal via Cape Verde and Senegal. The WASACE system will focus on developing new routes from Africa to Latin America and the US. The Company says that it will be offering two of the major international capacity routes and enabling three new underdeveloped direct traffic routes: Africa to the US, Africa to Latin America and Latin America to Europe. The key part of the project however is a link from Africa to the US via Brazil, which offers an alternative routing to North America that does not need to travel via Europe and the North Atlantic. It also has the potential to deliver connectivity from Asia to the US via Africa and Latin America as an alternative to Europe or the Pacific. Further WASACE is planned to be connected to the SEACOM cable system which runs on the East coast of Africa and branches to India and Europe. The project is divided into four sections; WASACE North connecting Europe to North America, WASACE South connecting South America to Africa, WASACE America connecting South America to North America and WASACE Africa connecting Nigeria, Angola and South Africa. The project is headed by WASACE Cable Company Worldwide Holding and project development will be managed by US-based David Ross Group. The company intends to get all four cables built by the end of the first quarter of 2014, prior to the FIFA World Cup that will take place summer 2014 in Brazil. Submarine cable vendors are planned to be selected in Q1 2012 and a supplier contract will be signed Q2 2012. WASCASE Cable Company Worldwide holding was originally formed to meet the increasing needs of the developing markets in the Global South.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
