Summary Chapter Description Vivek Alwayn discusses in this chapter the increasing demand of optical-fiber and its wide spread applications ranging from global networks to desktop computers. Fiber-optic cables are constructed of three types of materials:
Fiber-optic communication Optical fiber is used as a medium Fiber optic communication telecommunication and computer networking because it is flexible and can be bundled as cables.
It is especially advantageous for long-distance communications, because light propagates through the fiber with much lower attenuation compared to electrical cables. This allows long distances to be spanned with few repeaters.
The net data rate data rate without overhead bytes per fiber is the per-channel data rate reduced by the FEC overhead, multiplied by the number of channels usually up to 80 in commercial dense WDM systems as of [update]. Fiber is also immune to electrical interference; there is no cross-talk between signals in different cables, and no pickup of environmental noise.

Non-armored fiber cables do not conduct electricity, which makes fiber a good solution for protecting communications equipment in high voltage environments, such as power generation facilities, or metal communication structures prone to lightning strikes.
They can also be used in environments where explosive fumes are present, without danger of ignition. Wiretapping in this case, fiber tapping is more difficult compared to electrical connections, and there are concentric dual-core fibers that are said to be tap-proof.
For example, most high-definition televisions offer a digital audio optical connection.

May The advantages of optical fiber communication with respect to copper wire systems are: A single optical fiber can carry over 3, full-duplex voice calls or 90, TV channels.
Immunity to electromagnetic interference: Light transmission through optical fibers is unaffected by other electromagnetic radiation nearby. The optical fiber is electrically non-conductive, so it does not act as an antenna to pick up electromagnetic signals.
Information traveling inside the optical fiber is immune to electromagnetic interferenceeven electromagnetic pulses generated by nuclear devices. Low attenuation loss over long distances: Attenuation loss can be as low as 0.
Optical fibers do not conduct electricity, preventing problems with ground loops and conduction of lightning. Optical fibers can be strung on poles alongside high voltage power cables. Material cost and theft prevention: Conventional cable systems use large amounts of copper. Global copper prices experienced a boom in the s, and copper has been a target of metal theft.
Security of information passed down the cable: Copper can be tapped with very little chance of detection.Fiber-Optic Communication Systems [Govind P. Agrawal] on vetconnexx.com *FREE* shipping on qualifying offers.

This chapter includes the following sections: A Brief History of Fiber-Optic Communications—This section discusses the history of fiber optics, from the optical semaphore telegraph to the invention of the first clad glass fiber invented by Abraham Van vetconnexx.com more than 80 percent of the world's long-distance voice and data traffic is carried over optical-fiber cables.
Fiber Connectors A fiber optic splice establishes an optical connection between two individual optical fibers. It may be required to fix broken fiber connection or to tap the fiber for additionalconnections EE Telecom. Switching & Transmission Prof. Murat Torlak. SONET. For gigabits and beyond gigabits transmission of data, the fiber optic communication is the ideal choice.
This type of communication is used to transmit voice, video, telemetry and data over long distances and local area networks or computer networks.A fiber Optic Communication System uses light wave technology to transmit the data over a fiber by changing electronic signals into light.
