OVER VIEW OF Fiber Optic Cable- More Info ADVANTAGES OVER COPPER:
SPEED: Fiber optic networks operate at high speeds - up into the gigabits
BANDWIDTH: large carrying capacity
DISTANCE: Signals can be transmitted
further without needing to be "refreshed" or strengthened.
RESISTANCE: Greater resistance to electromagnetic noise such as radios, motors
or other nearby cables.
MAINTENANCE: Fiber Optic Cable- More Infos costs much less
recent years it has become apparent that fiber-optics are steadily replacing copper
wire as an appropriate means of communication signal transmission. They span the
long distances between local phone systems as well as providing the backbone for
many network systems. Other system users include cable television services, university
campuses, office buildings, industrial plants, and electric utility companies.
fiber-optic system is similar to the copper wire system that fiber-optics is replacing.
The difference is that fiber-optics use light pulses to transmit information down
fiber lines instead of using electronic pulses to transmit information down copper
lines. Looking at the components in a fiber-optic chain will give a better understanding
of how the system works in conjunction with wire based systems.
one end of the system is a transmitter. This is the place of origin for information
coming on to fiber-optic lines. The transmitter accepts coded electronic pulse
information coming from copper wire. It then processes and translates that information
into equivalently coded light pulses. A light-emitting diode (LED) or an injection-laser
diode (ILD) can be used for generating the light pulses. Using a lens, the light
pulses are funneled into the fiber-optic medium where they transmit themselves
down the line.

If you shine a flashlight in one
you can see light at the far end - even if bent the roll around a corner.
pulses move easily down the fiber-optic line because of a principle known as total
internal reflection. "This principle of total internal reflection states
that when the angle of incidence exceeds a critical value, light cannot get out
of the glass; instead, the light bounces back in. When this principle is applied
to the construction of the fiber-optic strand, it is possible to transmit information
down fiber lines in the form of light pulses.
Multimode cable is made of of
glass fibers, with a common diameters in the 50-to-100 micron range for the light
carry component (the most common size is 62.5). POF is a newer plastic-based cable
which promises performance similar to glass cable on very short runs, but at a
fiber gives you high bandwidth at high speeds over medium distances. Light waves
are dispersed into numerous paths, or modes, as they travel through the cable's
core typically 850 or 1300nm. Typical multimode fiber core diameters are 50, 62.5,
and 100 micrometers. However, in long cable runs (greater than 3000 feet [914.4
ml), multiple paths of light can cause signal distortion at the receiving end,
resulting in an unclear and incomplete data transmission. The use of fiber-optics
was generally not available until 1970 when Corning Glass Works was able to produce
a fiber with a loss of 20 dB/km. It was recognized that optical fiber would be
feasible for telecommunication transmission only if glass could be developed so
pure that attenuation would be 20dB/km or less. That is, 1% of the light would
remain after traveling 1 km. Today's optical fiber attenuation ranges from 0.5dB/km
to 1000dB/km depending on the optical fiber used. Attenuation limits are based
on intended application.
applications of optical fiber communications have increased at a rapid rate, since
the first commercial installation of a fiber-optic system in 1977. Telephone companies
began early on, replacing their old copper wire systems with optical fiber lines.
Today's telephone companies use optical fiber throughout their system as the backbone
architecture and as the long-distance connection between city phone systems.
television companies have also began integrating fiber-optics into their cable
systems. The trunk lines that connect central offices have generally been replaced
with optical fiber. Some providers have begun experimenting with fiber to the
curb using a fiber/coaxial hybrid. Such a hybrid allows for the integration of
fiber and coaxial at a neighborhood location. This location, called a node, would
provide the optical receiver that converts the light impulses back to electronic
signals. The signals could then be fed to individual homes via coaxial cable.
Area Networks (LAN) is a collective group of computers, or computer systems, connected
to each other allowing for shared program software or data bases. Colleges, universities,
office buildings, and industrial plants, just to name a few, all make use of optical
fiber within their LAN systems.
companies are an emerging group that have begun to utilize fiber-optics in their
communication systems. Most power utilities already have fiber-optic communication
systems in use for monitoring their power grid systems.
