Principle of Operation

An optical fiber basically consists of a dielectric waveguide (nonconducting waveguide) which is cylindrical in shape which transmits the ray of light through a process known as total internal reflection. The optical fiber basically contains a core at the center which is surrounded or covered with a layer of cladding, and the core and cladding layer is made up of a dielectric medium. In order to make sure that the confinement of the optical signal in the core, the refractive index of the core is kept or maintain greater than the refractive index of the cladding. They interfere or boundary line between the core and the cladding may be either gradual in gradual-index fiber or abrupt in step-index fiber. Light can be fed into optical fibers with the help of LEDs or lasers. Precision optics manufacturers and custom optical prism manufacturer are selected from the best optical lenses manufacturer to design and manufacture custom prisms which are then used for a specific purpose.

Optical Fiber Ability

Optical fiber has the ability to withstand electrical interference; there is the total absence of any kind of cross-talk between signals in different cables and no pickup of environmental noise. The information which travels through the optical fiber is also immune to electromagnetic pulses generated by nuclear devices. Fiber cables are resistant to electricity and do not allow the flow of electricity which makes fiber useful for protecting communication equipment in high voltage environments such as applications prone to lightning strikes or power generation facilities. The electrical isolation prevents any kind of problem to happen with ground loops. Because of the fact that optical cables do not allow the flow of electricity through them that could potentially generate sparks, they can be used in environments where explosive fumes are present. Wiretapping is more difficult than electrical connections.

Fiber cables are not a victim of metal theft. On the other hand, manufacturing of copper cables requires copper in huge amounts and they have been in the bright spot for theft since the 2000s commodities born.

We can also use the optical fiber for the purpose of power transmission using a photovoltaic cell which converts the light energy into electrical energy. While this method of power transmission is not as efficient as conventional methods, it is particularly useful in situations where it is desirable not to have metal conductors in the use case near MRI machines, which generate strong magnetic fields. There are some examples that are used to power electrons with the help of high-powered antenna elements and devices which are used for the measurement purpose in high-voltage transmission equipment.
