Fiber Optic Cable Components and How a Fiber Optic System Works The world of fiber optic technology seems to be new. While in reality it dates back to the 1800s. It was primitive but it was a form of fiber optics. In this article I will tell you what a fiber optic cable is made of, how a fiber optic system works, and a history of fiber optics from 1800 to today. Let's look at optical fibers, what these fibers do is carry the light that is transmitted to the destination. Now we will see what a cable is made of. A cable is made up of five different sections. We will start from the center and find our way out. In the center of the cable is the core. The core is the light-transmitting section of the fiber and is made of silica. The next layer of the fiber is the most important for the travel of light along the cable. It's the lining. The coating acts as a guide for light waves. This is important because light moves in waves and escapes from the nucleus. The coating reflects light into the core. The lining is made of pure silica. The middle layer of the cable is called the buffer. The pad is a protective layer made of acrylic polymer and its only function is to protect the coating and core. As for the fourth level, this level is for installation purpose. It is called a member of the force; its function is to add force as the cable is pulled. It needs this section because the core is very small and if the wire breaks it will be unusable. The final section of the cable is the outer sheath, typically made of one or more layers of a polymer that protects the structure from physical or environmental damage. There are also t... middle of paper...... ways to the houses, at least for the services present. Instead, telephone and cable companies run twisted pairs of wires or coaxial cables from optical network units to individual homes. The world of fiber optics is a new technology, but that's only because we didn't have a good medium to send the light wave to. there destinations. That's why the invention of single-mode fibers had a huge impact on the world of fiber optics and communications. Eighty percent of the world's long-distance telephone calls are made via fiber optic cable. Fiber optic bandwidth has also changed the way the telecommunications industry must act. Before fiber optics they would have had to run hundreds of cables. Now all they have to manage is a single line to serve hundreds of people. As we rely more on technology, it is good to know that fiber optics is one of the most reliable forms of communication.
