Broad, thin strands of carefully drawn glass about the diameter of a human hair are fibers optics, or optical fibers. In bundles called optical cables, these strands are arranged. To relay light signals over long distances, we rely on them.
The light signals are encoded at the transmitting source with data the same data you see on a computer’s screen. Thus, the optical fiber transmits “information” to the receiving end by light, where the light signal is decoded as information. Fiber optics is thus essentially a transmitting medium, a “pipe” to carry signals at extremely high speeds over long distances.
For endoscopes, fiber optic cables were originally developed in the 1950s. The aim was to help doctors without major surgery view the inside of a human patient.
- How Do Fiber Optics Work?
Light passes down a fiber optic cable by continuously bouncing off the cable’s walls. With continued internal mirror-like reflection, each light particle (photon) bounces down the pipe.
The beam of light travels down the cable core the middle of the cable and the glass framework are the heart. Another layer of glass wrapped around the heart is the cladding. To keep the light signals within the heart, cladding is there.
Advances in communication technology have led to the introduction of a new communication method that not only makes the environment faster, but also more efficient and lighter. Known as fiber optics, this technology has significantly improved the speed at which people can now communicate.
Let’s look at some of the benefits of fiber optic technology more closely and what makes it the perfect form of communication.
- Immunity: Fiber optics, for example, is resistant to electromagnetic interference. This implies that the signal sent from one end is exactly the same signal received at the other end. Other factors such as wave-emitting lightning and heavy industries have little effect on fiber optic signals, making the device a very beneficial means of communication. Fiber cable signals cannot be interfered with by outside signals, making them excellent for sensitive data.
- Secure communication: Given the fact that fiber optic cables use light for communication instead of electric currents, when used in communication, they are more reliable. A fiber optic version of a wiretap is very difficult to do because there is a great deal of knowledge flowing through these cables. Fiber optics are much more secure, and the information passed is shielded from tapping by malicious users when it is used for communication.
- Easily to be installed: Given that fiber optic cables are just a fraction of the weight of conventional copper cables, they are extremely easy to transport and often easy to install from one place to another. To install, they require less manpower, which means lower construction costs. The ease of implementation also makes it easy and much quicker to deploy fiber optic networks. Since fiber optics is smaller, it is very easy during the installation process to bring them around. Leaving them out at night in the open does not expose them to corrosion and other environmental variables that conventional copper cables face.
