INTRODUCTION
The light is contained within the glass core
and cladding by careful design of their
refractive indices. The loss along the fiber is
low and the signal is not subject to
electromagnetic interference which plagues
other methods of signal transmission, such as
radio or copper wire links.

1.During 1930, other ideas were developed with this fiber optic such as
transmitting images through a fiber.
During the 1960s, Lasers were introduced as efficient light sources
In 1970s All glass fibers experienced excessive optical loss, the loss of the light
signal as it traveled the fiber limiting transmission distance.
2. This motivated the scientists to develop glass fibers that include a separating
glass coating. The innermost region was used to transmit the light, while the
glass coating prevented the light from leaking out of the core by reflecting the
light within the boundaries of the core.
3. Today, you can find fiber optics used in variety of applications such as medical
environment to the broadcasting industry. It is used to transmit voice, television,
images and data signals through small flexible threads of glass or plastic.

9. Optical hen sending information by an fiber, the
information must be encoded or transformed
somehow into information that capable of being
transmitted through a fiber. The signal needs to be
modulated. There are two types of modulation
Analog and digital.

The advantages of optical fiber over wire cable

11. Disadvantage of optical fiber over copper wire cable
11
 Optical fiber is more expensive per meter than copper
 Optical fiber can not be join together as easily as copper
cable. It requires training and expensive splicing and
measurement equipment.
