1.1 Why Fiber Optic Solutions?

The fiber-optic communications permits transmission over longer distances than other
forms of communications because of the signals travel along them with less loss and no
crosstalk. It has following important features: Immunity to electromagnetic interference
(EMI) — Motors, relays, welders and other industrial equipment generate a tremendous
amount of electrical noise that can cause major problems with copper cabling.

High electrical resistance, making it safe to use near high-voltage equipment or
between areas with different earth potentials.
No sparks — important in flammable or explosive gas environments.

Not electromagnetically radiating, and difficult to tap without disrupting the signal —

important in high-security environments.

Because of these reasons, optical fibers have largely replaced copper wire
communications in core networks in the developed world.
