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.
Fiber Cable parts
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
