Equatorial Guinea plans to extend the fibre-optic cable from its capital Malabo to Ilha do Principe in Sao Tome and Principe, according to the president of the Regional Government of Principe, Jose Cassandra. He said that he discussed the issue with the president of Equatorial Guinea, Teodoro Obiang Ngema Mbasogo, who expressed his readiness to support the proposal to connect with the cable that arrives from Cameroon and goes via Malabo.
An optical fiber cable is a cable containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. Different types of cable are used for different applications, for example long distance telecommunication, or providing a high-speed data connection between different parts of a building. Optical cables transfer data at the speed of light in glass. This is the speed of light in vacuum divided by the refractive index of the glass used, typically around 180,000 to 200,000 km/s, resulting in 5.0 to 5.5 microseconds of latency per km. Thus the round-trip delay time for 1000 km is around 11 milliseconds.
Príncipe is the smaller, northern major island of the country of São Tomé and Príncipe lying off the west coast of Africa. It has an area of 136 sq km (53 sq mi) and a population of approximately 5,000. The island is a heavily eroded volcano speculated to be over three million years old, surrounded by smaller islands including Ilheu Bom Bom, Ilhéu Caroço, Tinhosa Grande and Tinhosa Pequena. Part of the Cameroon Line archipelago, Príncipe rises in the south to 948 metres at Pico de Príncipe, in a thickly forested area forming part of the Obo National Park.
