Fiber Optic Communication

Fiber Optic Communication Fiber-optic communication is a method of transmitting.1 information from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic carrier wave that is modulatedto carry .information The process of communicating using fiber-optics involves.2 the following basic steps: Creating the optical signal involving the use a transmitter, relaying the signal along the fiber, ensuring that the signal does not become too distorted or weak, receiving the optical signal, and .converting it into an electrical signal Optical fiber can be used as a medium for.3 telecommunication and 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 little attenuation .compared to electrical cables There are more parts to the fiber optic system than the.4 cables. The first thing is the transmitter. It produces the signals that will travel through the cable. The optical regenerator is needed when the light signal is weakened by traveling over a long distance . Finally, there is the optical receiver. It receives the light signals and encodes .them into a readable form for the device at the end :Fiber optics have lots of uses.5 .The Internet uses fiber optic cables* .Telephones were one of the first uses for fiber optics* .Digital television is often transmitted by fiber optic cables * : Three other kinds of uses.6 Surgeons use special scopes using‫ ؛‬One is medical imaging* fiber optics to enlarge areas of patients that are hard to see, .kind of like a very accurate magnifying glass .A very similar use is mechanical inspection* Engineers and mechanics can use a similar scope device to* .see hard to reach places during safety inspections .Another similar use is to inspect plumbing and sewer lines * Fiber optic cables without optical regenerators can be up to.7 about one kilometer in length. With regenerators, they can go on almost forever. They can be placed in buildings, up

on power lines, buried in the ground or even placed in the !ocean Fiber optic cables are not perfect; they can break..8 Sometimes when crews are digging, they accidentally can tear up the cables. They can be repaired using a technique .called splicing There are many advantages of fiber optics over traditional.9 .wire cables Less Expensive. First, fiber optics are less expensive than• copper wire. This is because many miles of optical cable are easier and less expensive to install than the same .amount of copper wire or cable Thinner. Fiber optics are thinner than copper wire cables,• so they will fit in smaller, more crowded places. This is .important for underground cable systems Higher Carrying Capacity.More information can also be• carried over fiber optic systems. This can be especially important for computers, phone lines Many people use the same optical cable for phone conversations at the same .time Less signal degradation.fiber optic cables don’t lose as• much signal (information) as other kinds of wires and .cables Use Light Signals. Because fiber optics use light signals• the signals don’t interfere with each other. This makes the .signals clearer and easier to understand Low Power. Optical fiber signals are created using low-• power transmitters. Lower power use saves money for .users and providers Digital Signals. fiber optic cables send information• digitally, they are the best thing to use for computer .networks Non-flammable. fiber optics are non-flammable. This• means there is not a fire hazard. Fiber optics also do not .cause electric shocks, because they do not carry electricity Light weight. Fiber optics are easier to install and• transport than copper wires. That is good news for technicians Flexible. Since fiber optics are more flexible, they can go• around corners and into tighter places than traditional .cable Fiber optic cables are really amazing. They are used a lot.10 today on computers, cable television, and the most .common use in telephone communication
