Using light instead of electricity, Optical fibers have advanced
the speed of communications to the point where billions of bits
of information can be transmitted over a single glass strand in
a fraction of a second. Some 10 billion digital bits can be transmitted
per second along an optical fiber link in a commercial network,
enough to carry tens of thousands of telephone calls.
Fiber-optic cable also has a wider signal frequency bandwidth than
coaxial cable. This means more available channels of communication.
For example, metallic coaxial cable has an effective bandwidth of
10 MHz. By comparison, fiber-optic cable has an effective bandwidth
of 44.6 MHz. This means an effective potential of more than 670
simultaneous telephone conversations over one glass fiber.
Installers are using more fiber-optic cable than ever before. One
reason is, there are more channels of communication over which to
transmit video images, audio and other data. This means more images
on a single cable than is possible with metallic coaxial cable.
Longer signal transmission distances are also possible with less
signal attenuation using fiber-optic cable.
Fiber-optic cable is also unaffected by electromagnetic interference
(EMI), like coaxial. It's also generally smaller in diameter than
metallic coaxial cable when it comes to the number of communication
channels that's available. Signal transmissions are also more secure
using fiber-optic cable. This is because the signals traveling on
a fiber-optic cable do not emit electromagnetic radiation that someone
can pickup with a EM-sensitive device and use. This makes it more
difficult to tap with the intent of eavesdropping. To do so in an
unauthorized manner will also introduce extreme signal loss or even
total signal disruption.
