Cutaway diagram of a shielded multicore cable with four cores each with three individual conductors. A multicore cable is a type of electrical cable that combines multiple signals or power feeds into a single jacketed cable. [1] The term is normally only used in relation to a cable that has more cores than commonly encountered. [2]
The GLO-1 submarine communications cable is a cable system along the west coast of Africa between Nigeria and the UK, owned by Nigerian telecoms operator Globacom.. The submarine cable system is 9,800 km long, and became operational in 2011 with a minimum capacity of 640 Gbit/s.
The Main One Cable is a submarine communications cable stretching from Portugal to South Africa with landings along the route in various west African countries. On April 28, 2008, it was announced that Main Street Technologies has awarded a turnkey supply contract for the Main One Cable System to Tyco Telecommunications .
GLO-1 is the first successful submarine cable from the United Kingdom to Nigeria, and GLO is the first individual African company to embark on such a project. [11] [12]GLO-1 has the potential to provide high speed internet services, faster, more reliable and cheaper telecom services. [13]

In 2015, her company started operations of what is reputed to be Nigeria's largest Tier III Data Center, also extending a submarine cable from Lagos into Cameroon. [13] Her achievements are a source of inspiration to many. [14] Funke is the inventor of Mainstreet Technologies, the developer of MainOne cable, a leading provider in West Africa. [15]
If the MI cable jacket has been damaged, the magnesium oxide will wick moisture into the cable, and it will lose its insulating properties, causing shorts to the copper cladding and thence to earth. It is often necessary to remove 0.5 to 2 metres (1.6 to 6.6 ft) of the MI cable and splice in a new section to accomplish the repair.
Comparison of SWG (red), AWG (blue) and IEC 60228 (black) wire gauge sizes from 0.03 to 200 mm² to scale on a 1 mm grid – in the SVG file, hover over a size to highlight it. In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameter, because the cross section is directly proportional to its strength and weight ...
