EXECUTIVE SUMMARY
The aim of the assignment is to allow one to acquire an in-depth
understanding of the technical aspects of the fiber optic-based
communication system.
The theoretical analysis of the communication system is followed up
by the lab experiment which reviews the splitting and combining of
fiber optic signals in the communication system

INTRODUCTION
• A link refers to the signal pathway between two points using some kind of generic
cable.
• A simple intercom, for instance, one that consists of the sending station and the wire
over which the signals are transmitted and the receiving station. There are several
types of links based on different kind of material and operating at different data rates.

FIBER COMMUNICATION SYSTEM
OVERVIEW

LAB EXPERIMENT
1. To identify all the physical quantities that can be measured using fiber optics technology
2. To classify the optical fiber-based sensors based on their technical operating principles.
3. To explain in detail the principles of operation of the fiber optics-based sensors used to measure
such quantities.
4. To discuss the performance, advantages and disadvantages of using the fiber optics-based
sensors in comparison to the traditional sensing techniques.
5. To multiplex and de-multiplex the different light wavelengths for commercial infrared-based
communications systems, specialized components; minimizing the losses.

DISCUSSION
• The fiber-based sensors in the technical operating principles
• These sensors measure the properties of their surroundings. They can measure
anything which changes the way light travels through the fiber or alters the
properties of light. There are a number of physical quantities that can be
measured using the fiber optics technology such as temperature, pressure, strain,
displacement, acceleration, flow rate, vibration, chemical concentrations,
electrical and magnetic fields, and rotation rate.

RECOMMENDATIONS
• Improvement of the micro bending sensor detection to ensure that
less light signals are lost as a result of the FOC bending beyond the
set or standard maximum angle of bending.

CONCLUSION
• The fiber communication system is efficient and effective in the delivery of
information especially over very long distances as well as in hostile environment
where human intervention is least required. The communication system allows
for multiplexing and demultiplexing, such that the data rates and communication
method performance is largely improved.
