In this research paper, I will discuss the history of fiber optics, who used it, who came up
with it, and why is was used then. I will also discuss the design of fiber optics, what is it
Q1. Explain the concepts of amplification and regeneration
Amplification multiplies the amplitude of a weak input signal but doesnt clean it up or reshape it.
Regeneration processes a weak input signal to regenerate the original input. It also amplifies t
Q1. Analyze the function of basic optical attenuators, an optical transmitter, optical fibers,
connector/coupler to make a single fiber communication link.
An optical attenuator, or fiber optic attenuator, is a device used to reduce the power level of an
Unit 6 assignment 1: noise calculations in fiber optics
Q1: Explain the concept of random noise in photo detector and electronic circuits
Q2: Explain the significance of thermal and shot-noise currents
Noise- unwanted random process; random fluctuations i
Q1: Explain the concept of signal coding and quality.
See page 263
Q2: Explain the design and operation of a sample receiver circuit.
Is an analog device that samples (captures, grabs) the voltage of a continuously varying analog signal and
Q1. Identify and compute different types of losses in fiber optics.
Differences between the fibers being spliced cause intrinsic losses. Extrinsic losses arise from the nature
of the splice itself. They depend on alignment of the fiber ends, quality of en

Unit 3 assignment 1: Fiber optics properties
Q1. Describe and compute fiber attenuation, absorption and scattering.
Attenuation (in some contexts also called extinction) is the gradual loss in intensity of any kind of flux
through a medium. For instance,

What is the need for fiber-optic communications?
Because of its advantages over electrical transmission, optical fibers have largely replaced
copper wire communications in core networks in the developed world. Optical fiber is used by
