 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
Fiber Cable parts
 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.
 Increased hacking - Unauthorized attempts to bypass
the security mechanisms of an information system or
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
 More system attacks.
 Faster communication e.g. mobile phone
 High costs of maintenance especially in cases of
 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
