Here is the advantages of Optical Fiber Communications
Wide bandwidth
The light wave occupies the frequency range between 2 x 1012 Hz to 7 x 1012 Hz. Thus the information carrying capability of fiber optic cables is much higher.
Low losses
Fiber optic cables offers bery less signal attenuation over long distances. Typically it is less than 1 dB/km. This enables longer distance between repeaters.
Immune to cross talk
Fiber optic cables has very high immunity to electricaland magnetic field. Since fiber optic cables are non-conductors of electricity hence they do not produce magnetic field. Thus fiber optic cables are immune to cross talk between cables cause dby magnetic
Interference immune
Fiber optic cable sar eimmune to conductive and radiative interferences caused by electrical noise sources such as lighting, electric motors, fluorescent lights.
Light weight
As fiber cables are made of silica glass or plastic which is much lighter than copper or aluminium Light weight fiber cables are cheaper to transport.
Small size
The diameter of fiber is much smaller compared to other cables, therefore fiber calbe is small in size, requires less storage
More strength
Fiber cables are stronger and rugged hence can support more
Security
Fiber cables are more secure than other cables. It is almost impossible to tap into a fiber cable as they do n ot radiate signals.
No ground loops exist between optical fibers hence they are more secure.
Long distance transmission
Becaujse of less attenuation transmission at a longer distance is
Environment immune
Fiber calbes are more immune to environmental extremes. They can operate over a large temperature Also they are not affected by corrosive liquids and gases.
Sage and easy installation
Fiber cables are safer and easier to install and maintain. They are non-conductors hence there is no shock hazards as no current or voltage is associated with Their small size and light weight feature makes installation easier.
Less cost
Cost of fiber optic system is less compated to any other
