Fiber optic cables use glass (or plastic) threads (fibers) to transmit data. These threads are capable of transmitting messages modulated onto light waves. Fiber optics is a particularly popular technology for local-area networks and many telephone companies have begun to adopt it in place of traditional telephone lines.
In recent years, network providers and fiber optic companies have taken advantage of expansion opportunities in Africa, building new cables and growing their customer base. Despite this growth, however, Africa remains one of the least connected continents and many wonder if Fiber Optics is the best solution for the continent due to its high cost. The implementation of new cables in coming years will determine the future of the technology on the continent.
