Fiber Optic Cable
A fiber optic cable is made of glass or plastic and transmits signals in the form of light pulses. An optical fiber is a thin flexible medium conducts pulses of light with each pulse representing a bit. A single optical fiber can support tremendous bit rates up to tens or even hundred of gigabits per second.
A thin glass fiber is encased in a plastic jacket which allows the fiber to bend without breaking. A transmitter at one end uses light emitting diode ( LED) or laser to send pulses of light down the fiber which are detected at the other end by a light sensitive transistor. Fibe optic cabling consists of a canter core surrounded by several layers of protective materials.
It transmits light rather than electronic signals eliminating teh problem of electrical interference. This make it ideal for certain environments that contain a large amount of electrical interference. It has also made it the standard for connecting networks between buildings due to its immunity to the effects of moisture and lighting
Fiber optic cable has the ability to transmit signals over much longer distances than coaxial and twisted pair. It also has the capability to carry information at vastly greater speeds. This capacity broadens communication possibilities to include services such as video conferencing and interactive services. The cost of fiber optic cabling is similar to copper cabling. However it is more difficult to install and modify.
