There are many types of communication systems in this world. Among all these, the optical fiber communication system has a place of its own. An optical fiber communication system has a number of attractive features that make it more convenient to use. To many, the advantages of this system have helped it to gain so much popularity. Let's have a look at the advantages of this communication system:
Enormous Potential Bandwidth
The optical carrier frequency is within the range of 1013 to 1016 Hz. Due to this large frequency range, it provides a far greater transmission bandwidth compared toi the normal cable systems.
Small Weight And Size
Optical fibers have very small diameters. These diameters are often no greater than a human hair. As a result, despite being covered with protective coatings, they are far smaller and much lighter than the corresponding copper cables.
Optical fibers are electrical insulators. Because of this, they do not exhibit earth loop and interface problems like their metal counterparts. Moreover, this property makes the transmission more suitable even in electrically hazardous environments.
Interference And Crosstalk Immunity
Optical fibers form a dielectric waveguide and hence they are free from electromagnetic interference (EMI), radio frequency interference (RFI) etc. As a result, the transmission in such a system is totally unaffected by a electrically noisy environment.
Security Of the Signal
The light from optical fibers does not radiate significantly and as a result they provide a high degree of signal security.
Low Transmission Loss
Due to the development in the technology over the last 20 years or so, modern optical fibers exhibit very low attenuation or transmission loss compared to the best copper conductors. The losses in cases of fibers are as low as 0.15 decibel per kilometer.
Flexibility And Ruggedness
With the development of technology, modern fibers are very much flexible and extremely rugged. Taking the weight and size advantage into account, these cables are normally superior in terms of transportation, storage, handling, installation etc. to the corresponding copper cables.
Easy Maintenance And System Reliability
Due to the low loss property of optical fibers, their system reliability is generally enhanced in comparison with the conventional electrical conductor systems. Also these systems are easy to maintain in this world of modern technology. The maintenance costs are also low.
Potential Low Cost
The glass that is normally used in the making of the fibers is made from sand, not any scarce resource. As a result, in comparison with the copper conductors, these systems offer the potential for low-cost line communication.
