Merits of Optical Fiber

The advantage of optical fiber is a lot. Some of the advantage of optical fiber is as follows, like small size and weight, electrical isolation, immunity to interference and crosstalk, ruggedness and flexibility, system reliability and ease of maintenance.

Small Size and weight:

Optical fiber have very small diameters which are often no greater than the diameter of a human hair. Hence, even when such fibers are covered with protective coatings they are far smaller and much lighter than corresponding copper cables. This is a tremendous boon towards the alleviation of duet congestion in cities, as well as allowing for an expansion of signal transmission within mobiles such as aircraft, satellites and even ships.

Electrical isolation:

Optical fibers which are fabricated from glass, or sometimes a plastic polymer, are electrical insulators and therefore, unlike their metallic counterparts, they do not exhibit earth loop and interface problems.

Immunity to interference and crosstalk:

Optical fibers from a dielectric waveguide and are therefore free from electromagnetic interference, radio frequency interference, or switching transients giving electromagnetic signals.

Ruggedness and flexibility:

 Although protective coatings are essential, optical fibers may be manufactured with very tensile strengths. Perhaps surprisingly for a glassy substance, the fibers may also be bent to quite small radii or twisted without damage.
