Fibre Optic cable and impacts in Kenya By Franklin Mutuma D61/71648/2008
Definition • Fiber Optic – refers to technology that uses cables made up of thin glass fibers that can conduct the light generated by lasers for high-speed telecommunications.
Introduction • According to James Obrien (O'brien, 2002) Fiber optic cable has one or more filaments of grass enclosed in a protective jacket. It can achieve transmission speeds of 320 billion bits per second. This translates to about 640 times better than coaxial and 32,000 times better than twisted pair. • Fiber-optic communications is based on the principle that light in a glass medium can carry more information over longer distances than electrical signals can carry in a copper or coaxial medium or radio frequencies through a wireless medium.
Currently Kenya is connected by two fiber cables from the following companies. • TEAMS • SEACOM
Impacts • Increased hacking - Unauthorized attempts to bypass the security mechanisms of an information system or network • Faster connection speeds to the internet • More jobs created. • Closing down of companies due to competition • Uptake of e-commerce activities locally. • Over reliance on one connection cause loss of business
Impacts • More system attacks. • Faster communication e.g. mobile phone • High costs of maintenance especially in cases of sabotage. • Decentralization of government services
Advantages of Fiber • Faster connection • Less prone to vandalism
Disadvantages of fiber • High cost of Installing and maintaining • Prone to sabotage by business competitors e.g. Telkom Kenya spend Shs. 12 Million monthly to repair
