What is fiber optics?

Introduction

When it comes to transmission or movement of things from one place to another, this movement is only made possible through the help of some mediums. This can be seen in our everyday life’s as we use cars, buses, and trains to move from our homes to our place of work or schools. It is not too different when it comes to fiber optics it is also a medium used in transmission.

Fiber optics

Fiber optics

Fiber optics refers to a way and technology behind the transmission information or data in form of light pulses through plastic or glass strand or fiber. This transmission of information through light particles or photons is only possible through the help of fiber optic cable and it only made possible by a process called total internal refraction. Although the information in this fiber optic cable travels at very high speeds, it is still not up to the speed of light. This is due to some denser glass layers found in this cables.

Optic fiber is used in computer networking and telecommunication, this is majorly due to its flexible nature and the fact that it could be bundled as cables. Fiber optics are seen to have many advantages when used in long-distance communication due to light being able topropagates through these fibers with a much lower attenuation in comparison with normal electricity cables.

Sensors

Sensors

When it comes to the use of fiber optics in sensors, it is seen that sometimes the sensor itself is actually an optical fiber. In some other cases, optical fiber is used in the connection of a measurement system to a non fiberoptic sensor. most times fiber optics are used as sensor to measuretempreture, pressure, strains and so many other quantities. This is done bymodifying a fiber to make its properties modulates the phase, polarization,wavelength, transit time or intensity of lights in the fiber.

Transmission of power

Transmission of power

Optical fiber are used to transmit power by making use of a photovoltaic cell to convert the light in them into electricity although this methodof transmission of electricity isn’t really as effective as the conventional way of electricity transmission, it is usually deployed when the used of metallicconductor are not really neededTypesThere are primarily two types of fiber optical cable namely single mode fiber and multimode fiber.

Single mode fiber

Single mode fiber

This type of fiber optic is used forlonger distances majorly due to it smaller diameter of its glass fiber core,which reduces the possibility for any attenuation which is the reduction in signal strength, the light areisolated into a single beam through theaid of small openings, this allows the light to travel long distances with thehelp of smaller and direct routes.

Multimode fiber

This type of fiber optic is used for shorter distances travels majoritydue to the larger core openings whichallows light signals to reflect and bounce even more along the way. The increasein diameter allows multiple light pulses to flow through the cable at aparticular time, which aid in more datatransmission.
