Optical fibers have many good qualities that make it highly useful in different fields of our life. Here we will discuss various advantages (benefits) of Optical Fiber Communication

Advantages of Optical Fiber Communication

1.Low transmission losses

2.Huge potential bandwidth 

3.Small size, low weight and high flexibility.

4.Electrical isolation

5.Security of signal

6.No cross-talk and immunity to interference

7.Potential low cost

8.Reliable system

9.Not attractive for theft

1.Optical Fibers offer Low Transmission Losses

*Total Internal Reflection (TIR) phenomenon takes place in optical fibers, which offer very low losses.

*Large spacing between repeaters is possible due to low losses

*Optical fibres can be used for long distance communication

*Transmission Losses are very low (0.2 decible/kilometre)

*Negligible transmission Losses in optical fibers are due to the following reasons-

 #Material absorption

 #Linear and nonlinear scattering

 #Fibre bend losses

2.Optical Fibers Provide Huge Potential Bandwidth

*Light rays are used as the carrier waves. The light rays have very high frequency.

*The optical fibers provide very large bandwidth due to this high frequency carrier, since as the carrier frequency increases, the bandwidth increases.

*Bandwidth of optical fibers is around 10^14 Hertz.

3.Optical Fibers are of Small Size, Low Weight and have High Flexibility

*Diameter of Optical Fibers is very small (slightly more than that of human hair)

*Optical fibers occupy less space

*These are very light weight

*Highly flexible

*Easy to transport and Store

*Optical fibers can be very useful at highly populated places to reduce congestion as these occupy less space

4.Electrical Isolation is provided by Optical Fibers 

*Optical fibers are made of glass (silica) or plastic, these are nothing but the insulators.

*So the light rays travel inside the insulating material

*Therefore there is no chance of electrical shock, short circuit or sparking hazards etc.

5.Signal Security is also an advantage of using Optical Fibers 

*Light rays propagate inside the core of the optical fiber

*Hacking of the signal is not possible

*If someone tries to steal the signals, then it can be easily detected.

*This feature of optical fibers is useful especially for military, banking and sending secret messages.

6.Optical Fibers help in No Crosstalk and are Immune to Interference

*In optical fibers, there is no interference in electrically noisy environment.

*There is no effect of EMI or RFI.

*Fibers can be cabled together without any cross-talk 

7.Optical Fibers have Potentially Low Cost

*Optical fibers are made of glass (silica/sand) or plastic, available in plenty, so the cost of optical fibers is very low.

*Repeaters and other electronics is required in less amount

*Low cost of transportation, handling, storage and installation etc.

*LASER and photodiode, fiber connectors and couplers are expensive (Disadvantage)

8.Optical Fiber Communication System is very reliable

*Repeaters, amplifiers and other electronics is required in less amount, which makes it more reliable.

*Optical fibers can easily serve for 20-30 years

*High reliability reduces the maintenance and maintenance cost.

9.Optical Fibers are Not Attractive for Theft

*As we know, that optical fibers are made of glass or plastic. since these materials are very cheap, therefore there is no risk of any theft.
