About This Book
This pioneering, course-tested text is the first to combine communications theory with the physics of optical communications. Comprehensive and rigorous, it brings together an in-depth treatment of the physical characteristics of the guided lightwave channel with the study of modern methods of algorithmic-based communication in time and space. The many different levels at which a lightwave communication signal can be described are integrated to provide a unified explanation of how a commonplace bit stream is transformed into a physical lightwave, how that lightwave travels through an optical fiber, and how it is then transformed back into the bit stream. Background fundamentals such as linear systems and electromagnetics are explained in relation to modern topics such as channel models, encoding, modulation and interference, and end-of-chapter problems are provided throughout. This is an essential text for students taking courses on optical communications, as well as researchers and professionals working in the area.

Introduction
A
vast
network
of
optical
fiber
continues
to
expand
beneath
the
surface
of
our
planet.
This
fiber
network
forms
the
communications
infrastructure
upon
which
sit
the
omnipresent
mobile
devices
that
now
bind
society
in
new
ways,
never
seen
before.
At
the
heart
of
this
network
is
the
seemingly
simple
and
passive
optical
fiber
made
of
glass
or
plastic
that
is
about
the
width
of
a
human
hair
yet
over
hundreds
of
kilo-
meters
long
when
used
in
wide-area
networks.
This
revolutionary
component,
though
largely
passive,
will
require
the
length
of
this
book
to
describe
how
it
is
used
to
convey
information.
This
introductory
chapter
presents
an
overview
of
digital
guided-lightwave
communication
systems,
emphasizing
the
differences
between
lightwave
and
other
types
of
communication
systems.
Communication
systems
convey
information
(voices,
images,
video,
or
data)
from
a
source
to
a
destination.
For
the
purpose
of
transmission,
modern
communication
systems
first
map
information
into
electronic
signals
that
can
be
either
analog
or
digital.
Analog
systems
map
information
into
a
continuous
physical
quantity.
A
digital
system
maps
or
encodes
information
into
a
sequence
of
discrete
logical
symbols
or
letters.
If
the
original
information
source
is
analog
(such
as
voice),
it
can
be
transmitted
digitally
by
first
digitizing
the
continuous
waveform
into
a
sequence
of
digital
symbols
by
sampling
and
quantizing
1
the
continuous
waveform
to
produce
a
sequence
of
sample
values.
The
combination
of
sampling
and
quantization
produces
a
sequence
of
digital
values.
The
set
of
logical
values
for
each
transmitted
symbol
is
called
the
channel
input
alphabet
,
with
each
discrete
value
being
a
letter
from
that
alphabet.
The
most
com-
mon
digital
symbol
has
two
possible
letter
values
and
is
called
a
bit
.
One
letter
is
called
one
or
high
or
mark
,
and
the
other
letter
is
called
zero
or
low
or
space
.
Symbols
in
other
alphabets
can
have
more
than
two
letter
values
and
can
be
represented
by
a
group
of
bits.
As
an
example,
the
keyboard
character
“$”
is
commonly
mapped
into
an
eight-bit
symbol.
This
keyboard
character
could
be
sent
as
eight
separate
two-state
letters
(bits)
or
it
could
be
sent
as
a
single
letter
drawn
from
an
alphabet
of
256
letters.
Every
point-to-point
digital
communication
system
conveys
data
between
a
source
and
a
destination.
Starting
with
the
source,
this
information
is
typically
handled
at
mul-
tiple
conceptual
layers
of
functionality
before
being
transmitted
over
a
communication
channel.
The
most
basic
of
these
hierarchical
communication
layers
is
known
as
the
physical
layer
or
the
modulation
layer
,
with
each
higher
layer
providing
additional
1
The
word
quantization
is
also
used
to
describe
the
discrete
nature
of
lightwave
signals.
