BackgroundIn this new era, we need a technology to improve our life

style. We have come out with a new idea than can make ourlife more efficient that is fiber optics.

Fiber optic is the overlap of applied science andengineering concerned with the design and application ofoptical fibers. The introduction of fiber optic technology hashad a dramatic effect on the Communications industry.

Generally, this fiber optic is used for transfer datatransmitted on a beam of light which is more effective than

before.

Objective The objectives of this research was to

discuss more on the process of fibre optic, theuses conventional information transfer system,the application of the optical fiber, the

manufactured of the optical fibre and theadvantages of fibre optic.


5/27

Scope Our research project will focus more on the

application of the optical fibre, the usesconventional information transfer system, how

fibre optic operate (the process), and themanufactured of the optical fibre and theadvantages of fibre optic. The investigationincludes laboratory model tests on fibre optic

that are conducted by previous scientist.


6/27

Organization The first part of this report is an outline of the

process of fibre optic which includes how it works andoperates. We will insert the laboratory model test that isconducted by previous scientist. This is followed by the

uses of the conventional information transfer systemthat are closely related to fibre optic since it is used intelecommunication. Then, we will discuss on theapplication and manufactured of fibre optic intelecommunication system. Finally, we will discussabout the important topic which are the advantages offibre optic.

Process of fiber opticFiber-optic communication is a method of

transmitting information from one place toanother by sending light through an opticalfiber.

The light forms an electromagnetic carrierwave that is modulated to carryinformation. Standard optical fibers are

made by first constructing a large-diameterperform, with a carefully controlledrefractive index profile, and then pulling theperform to form the long, thin optical fiber.


9/27

The process of communicating using

fiber-optics involves the following basicsteps:

Creating the optical signal using a

transmitter.Relaying the signal along the fiber.Ensuring that the signal does not

become too distorted or weak.Receiving the optical signal andconverting it into an electrical signal.


10/27

The application of the optical fiber Fibre optic was able to use for a long-distance communication

because of its ability to propagate through the fibre with littleattenuation.

This fibre has been used as a data transmission whereas it wasinvolve with the transmission of voice, data, or video over a

distance of less than a meter to hundred kilometers by using only afew standard fibre designs. Besides that, fibre optics is also used widely for transmission of

data signal. Private networks such as used in banks, university, ora big firms used fibre optic in order need for secure in

transmission data or private information between building to thecomputer, and around the world. In addition, fibre optic is also useful for video services. The high

information-carrying capacity or bandwidth of fibre makes it theperfect choice for transmitting signals to subscribers.


11/27

The advantages of fiber opticThere are several advantages over traditional

metal communication lines which are fiber opticcables have a much greater bandwidth thanmetal cables. This means that they can carry

more data.Furthermore, fiber optic cables are much thinner

and lighter than metal wires and also there areless susceptible than metal cables tointerference. Means, data can be transmitteddigitally (the natural form for computer data)rather than analogically.

In addition, telephone companies are steadilyreplacing traditional telephone lines with fiber

optic cables. Others advantages of optical fiber


12/27

Next, optical fiber has long lengths which iscontinuous lengths also provide

advantages for installers and end-users.Small diameters make it practical tomanufacture and install much longerlengths than for metallic cables.

Another advantage of fiber optic is relatedto its security which is unlike metallic-based systems, the dielectric nature ofoptical fiber makes it impossible to

remotely detect the signal beingtransmitted within the cable.

A fiber optic has easy installation andupgrades. Long lengths make optical cable

installation much easier and less

4.1 JUSTIFICATION THE

OBJCTIVE

The intent of this research is to discuss moreabout fiber optics in communication systems.Our research has revealed the process of fiber

optic with its manufactured and also uses of itin conventional information transfer system.We also discover out the application and itsadvantages. The study gives an insight the

significance of fiber optics in that system.


21/27

The objectives were achieved with the method ofarchival collection which we use the informationresources from internet, from the electrical book

to do more research about the process, uses, itsmanufactured, application and its advantages. Wealso do the questionnaire and a little observation

from the internet sources through out of elementsequipment.

4.2 REVIEWING THE SCOPE /

METHOD


22/27

As an electronic students, the most significant finding inthis researched was about the important uses of fiberoptic in helping the communication system especially intelecommunication system that use widely fiber optic.in

this findings, we apply the uses of fibre optic as fiber-optic communication systems have revolutionized thetelecommunications industry and played a major role inthe advent of the Information Age. Because of itsadvantages over electrical transmission, the use of opticalfiber has largely replaced copper wire communications incore networks in the developed world.

4.3 REVIEWING SIGNIFICANT

FINDINGS


23/27

This research can be explained by uses of fiber optic inthe communication systems that related in by manytelecommunications companies to transmit telephonesignals, Internet communication, and cable television

signals. This might due to information transmitted istypically digital information generated by computers,telephone systems and cable television companies.Generally, fiber-optic communication systems

include an optical transmitter to convert an electricalsignal into an optical signal to send into the opticalfiber.

4.4 EXPLANATION OF FINDINGS


24/27

Due to this research, this study was limited by someaspects of uses like fiber optics as sensor which otherapplication of fiber optics that extensively usednowadays. We also does not mention the fiber optic cable

splicing, a method joining two optical fiber, itcomparison with electrical transmission and also a fiberoptic connector which has many types.

4.5 LIMITATION OF STUDIES

25/27

This finding of the study implies that fiber optic veryimportant in the communication system because withoutit in that system, we still use the metal wire which has alot disadvantages. More over, in local area networks,

telephone companies are steadily replacing traditionaltelephone lines with fiber optic cables. In the future,almost all communications will employ fiber optics.

26/27

We recommend that, in further studies, we couldinclude the application of fiber optics in differentfield that using this fiber optics. Furthermore, uses infiber optics give a lot convenience in our technology

systems. We also hope that fiber optics will replacedall the metal cable in future and we will make thefiber optics is one of necessary in future technologies

by keep on increase the application of this fiber

optics.
