Optical
fiber is glass or plastic thread.
So this is the technology which
uses glass (or plastic) threads
(fibers) to transmit data. A fiber
optic cable consists of a bundle
of glass threads, each of which
is capable of transmitting messages
modulated onto light waves.
Optical
fiber is safer, faster and have
several advantages over traditional
metal communications lines:
-
Fiber optic
cables have a much greater bandwidth
than metal cables. So they can
carry more data.
-
Fiber optic
cables are less susceptible
than metal cables to interference.
-
Fiber optic
cables are much thinner and
lighter than metal wires.
-
Data can
be transmitted digitally (the
natural form for computer data)
rather than analogically.
-
Long Distance
Signal Transmission
-
The optical
fiber cable in the foreground
has the equivalent information-carrying
capacity of the copper cable
in the background.
-
Long Lengths
-
Long, continuous
lengths also provide advantages
for installers and end-users.
-
Easy Installation
and Upgrades
-
Long lengths
make optical cable installation
much easier and less expensive.
-
Non-Conductivity
-
Security
-
Designed
for Future Applications Needs
Fiber
optics is a particularly popular
technology for local-area networks.
In addition, telephone companies
are steadily replacing traditional
telephone lines with fiber optic
cables. In the future, almost all
communications will employ fiber
optics. |
