Optical Fibre Cable and the Way It Works

We often hear the term optical fibre cables or fiber-optic cables whenever people are talking about telephone systems, cable TV or the internet. Why is that so? What is optical fibre cable and do they work?
As defined by Wikipedia, optical fibre cable is a cable that contains one or more optical fibres. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment in which the cable will be deployed. Fibre cables are a bundle of thin glass threads that are capable of transmitting any amount of data without any loss of information. These fibres can be grouped together that will result to superior bandwidths in comparison to other kinds of transmitting information media.
In recent times, the use of fibre optics has been a prominent medium for high -speed transmissions of large amounts of data and computerized computer networking systems. This is the reason behind why it is possible to watch a show on TV, talk to a person halfway around the globe and get plenty of data from a computer system.
Despite being expensive, many companies spent large amount of money in order to install optical fibre cables and to have an un-interrupted and speedy transfer of information from different computer devices. How can it be possible? Once a fibre-optic communication system is in place between two places separated by thousands of miles, you can still transmit because of the following components:
Transmitter – this one produces and encodes the light signals.
Optical fiber – Conducts the light signals even from a distance.
Optical regenerator – This is necessary in order to boost the light signal especially for long distance.
Optical receiver – This is an instrument that receives and decodes light signals.
There can be an innumerable uses for fibre optic cables. It is one of the most in demands in the modern world. These cables are very useful not only in telecommunications but also in the medical field in the form of light guides, imaging and diagnostics. It is also used in sensory devices to detect slightest changes in temperature, pressure, vibrations and other parameters that can be measured. Aside from that, fibre optic cables made it possible for highly complicated wiring jobs can be made simple.
With the help of fibre optic technology, transport system can be revolutionized by intelligent traffic lights and automated tollbooths. Even the modern day military can make use of cables to quite a number of uses in the cost of fibre cables is minimized.
