Fiber Communication System
EXECUTIVE SUMMARY
The main focus of this report is on the fiber communication system. The optical fiber is
the backbone of the modern communication network. It carries all long distances voice data and
other multimedia forms of communication. Fiber communication systems are used in many
fields such as the power engineering, biomedical, optical sensing for structural monitoring and
VLSI in intra-chip communications. The device detects events or changes in the physical
quantities and provide a corresponding optical output. The sensor will modulate an optical signal
which when demodulated yields precise quantitative information. The economic perspective of
multiplexing benefits the organization hosting the FOC as the transmission costs less in terms of
physical resources such as cables and time. A corresponding multiplexer, or demultiplexer, is on
the end of the high-speed line and it is used to separate the multiplexed signals

INTRODUCTION
Fiber communication systems
The optical fiber is the backbone of the modern communication network. It carries all long
distances voice data and other multimedia forms of communication. The information revolution
can be attributed to the evolution of optical fiber in data communications. It is preferred because
of the low attenuation, very high bandwidth in the communication channel especially in the
single mode fiber, its enormous capacity, and the system adds an optical layer that guarantees
flexibility. Fiber communication systems are used in many fields such as the power engineering,
biomedical, optical sensing for structural monitoring and VLSI in intra-chip communications.
