Components of Fiber Optic Cable and How a Fiber Optic System Works The world of fiber optic technology seems to be new. While in actuality it dates back to the 1800's. It was primitive but it was a form of fiber optic. In this paper I will be telling you what a fiber optic cable is made of, how a fiber optic system works and a history of fiber optics from the 1800's to today. Lets take a look at the optical fibers, what these fiber do is carry the light which is transmitted to the destination. Now we will look at what a cable is made of. A cable is made up of five different sections. We will start in the middle and work our way out. At the middle of the cable is the core. The core is the light transmitting section of the fiber, and it is made of silica. The next layer of the fiber is the most important for the travel of light down the cable. It is the cladding. The cladding acts like a guide for the light waves. This is important because light moves in waves and will shoot out of the core. The cladding reflects the light back into the core. The cladding is made of pure silica. The middle layer of the cable is called the buffer. The buffer is a protective layer that is made of acrylic polymer and its only function is to protect the cladding and the core. As for the fourth layer, this layer is for installation purposes. It is called the strength member; its function is to add strength while the cable is being pulled. It needs this section because the core is very small and if it is broken the wire will be useless. The final section of the cable is the outer jacket typically consists of one or more layers of a polymer that protects against physical or environmental damage to the structure. There are also t... ... middle of paper ... ...way to homes, at least for present services. Instead, cable and phone companies run twisted wire pairs or coaxial cables from optical network units to individual homes. The world of fiber optics is a new technology but that is just because we didn't have a good medium which to send the light wave to there destinations. That's why the invention of single-mode fibers was huge in the world of fiber optics and communications. Eighty percent of the world's long distance telephone calls go over a fiber optic cable. The bandwidth of fiber optics has also changed how the telecommunications industry has to do things. Before fiber optics they would need to run hundreds of wires. Now all they have to run is a single line to serve hundreds of people. As we depend more on technology it is good to know that fiber optics are one of the most reliable forms of communication.
A third method is to program all cable boxes from the headend to display a

“Bulletproof vests are modern light armor specifically designed to protect the wearer's vital organs from injury caused by firearm projectiles” (“How Bulletproof Vest is Made”). Many people prefer calling them “bullet-resistant vests” because the person who wears the vest is not completely safe from a bullet. There are many components that go into making a vest. A vest-shaped sheet of advanced plastic polymers, called a panel, is composed of many layers of Kevlar or Spectra Shield. While, the layers of woven Kevlar are sewn together using Kevlar thread, the non-woven Spectra Shield is coated and bonded with resins. An example of a possible resin is Kraton. It is then sealed between two sheets of Polyethylene film. The panel is placed inside of a fabric shell that is made from nylon or a blend of cotton and polyester. Some bulletproof vests add nylon padding for extra protection. Many bulletproof vests contain built-in pouches that are used to hold plates. These plates are made from either ceramic bonded to fiberglass or metal. In order to keep the vest on, the sides are connected with elastic webbing, cloth, metallic buckles, or velcro closure...
In the development of expanding, Southern Light a private cable company plans on extending its fiber-optic services from the Gulf Coast to Huntsville, Alabama. Southern Light is the Gulf Coast’s leading provider of fiber optic networks and high-volume transport solutions. Southern Light markets affordable, high-bandwidth services over their own fiber optic network. In this research, I will discuss the history and main operates of this private business, then I will identify and analyze the four factors of production of Southern Light fiber. Next, I will identify and analyze the business environments that are affecting this business. The expanding of Southern Light affects the community and businesses

Being a government research project, the concept was introduced to the public, and companies were encouraged to compete for the right to develop the fibre. The in fact that multiple companies were competing for the development rights not only meant that it was cheap for the government to fund, but also that the final product would be high quality. Corning Ultimately won the developmental rights, and developed fibre optic cable into what we use today. The development of Fiber Optics has given us many benefits such as:

The new technology expanded words per minute. The words transferred per minute were up to a 1,000. It usually ranged to 25-40. Even when Thomas Edison was improving the telegraph he made new ones. People during the wars used the telegraph. This telegraph changed the world for people with hearing problems because he had them. He tried to work around his disadvantage. When trying to make the telegraph better, he managed to make another based on his perforated pen, that needed no one to tap out the message at the receiving end. Thomas Edison helped a lot of people. During World War 2 people used telegraphs to send messages to each other. Overall, Thomas Edison made the world more advanced and better for people who had disadvantages with
Most companies actually leased lines, but in either case both solutions are very expensive. As the Internet became more widely available people started creating VPN solutions that took advantage of the cheap network access. The idea was to use the Internet's existing links to create a virtual circuit.
By 1950, 70 cable systems served 14,000 subscribers nationwide. In late 1950s, when cable operators began to take advantage of their ability to pick up broadcast signals from hundreds of miles access to these "distant signals" changed the focus of cable's role from one of transmitting local broadcast signals to one of providing new programming choices.

A communications network can provide many types of service. The most basic type of service is known as simplex. This service provides one-way communication. Examples of this type of service are TV distribution, and the transmission of burglar alarm messages.

The disadvantage would be that it’s slow and it can interfere with emergency services communications [1].In the states to provide customers with broadband access several electric companies created this kind of connectivity so that their customers can connect to the internet, also this gave the companies a better way to manage and control the reliability of their electric grids [3].
The history of engineering goes back into the 19th century when Alexander Volta (1745-1827) made a remarkable discover regarding the nature of electricity (Cosgrove 749). He discovered that electrical current could be controlled and could flow from one point to another. By the time the mid-19th century came about the rules for electricity were being established. During this time electromagnetic induction was discovered by Michael Faraday who lived from 1791 to 1867 (749). Also during this time Samuel Morris invented the telegraph in 1837 which relies on the principles of electromagnetic induction (749). Alexander Graham Bell, who lived from 1847 to 1922, created the telephone which also uses electricity in order to operate (749). Through the success of the telephone, Bell Telephone Company was established. In 1878, the light bulb was finally invented by Thomas Edison who lived from 1847 to 1931 (749). Off the principles of Faraday’s electric motor from 1821, Nicholas Tesla invented a more efficient and powerful electric motor in 1888 (749). To make these inventions be more significant, effort was expended to make better motors and transformers and to enhance the power needed to make them function. Through these inventions during the middle 19th century, it led to the capability of lighting homes and cities through the use of electricity, and it also led to the creation of the telephone communication system (750).
