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.
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
It is five times stronger, yet the same weight as steel. Kevlar Aramid fiber is an improved material, which is an extremely lightweight, man-made organic fiber. Kevlar fiber has a combination of properties, which have made Kevlar a very useful material. These include, high strength, low weight, high chemical resistance and high cut resistance. This material does not corrode or rust and is also unaffected when placed in or under water.
Morse code and the telegraph were ingenious yet simple. Operators used a simple method of dots and dashes for letters and numbers. When the Morse Key was pressed the electric circuit was open and when released the electric circuit was closed. The electrical current traveled through the wire to a printer device that printed a tape of the code message which an operator would translate. This simple solution to communicating long distance has improved and evolved into a newer technology, the packet switch. The single signal wire has evolved into fiber optics. Communicating one at a time has evolved into mass communication.
Fiberglass has been the most recognizable composite material, and is made up of glass fibers inlayed in a resin matrix. Fiberglass got its start when it was first used in the 1950’s for autos and boats. Today most cars have a fiberglass bumper cover that is mounted to a steel frame. Fiberglass was first used on the design of the Boeing 707 airliner in the early 1950’s. The material accounted for about two percent of the planes structure. In the 1960’s, many more composite materials were being made available, in particular graphite and boron fiber, that was then inlayed in epoxy materials. The United States Air Force and United States Navy began their own research into using these types of materials for aircraft surfaces like ailerons, rudders and flaps. The first large scale military implementation of boron fiber was in the horizonta...
As the telephone was a faster and less tedious way of sending information, more people, who formerly used telegraphs, began to use it instead. Telegraph companies were losing business, and fast, to the object you and I can’t live without. The telephone’s gaining popularity was eventually going to end the use of the device that changed the world before, its predecessor, the telegraph.
Fiber optic cables do not carry electricity, which makes them ideal for volatile area's where a spark from a broken copper line could result in explosive consequences. If the fiber optic cable breaks, there is absolutely no risk of electrical shock. Also, the glass fiber will not oxidize like the copper or aluminum wire traditionally used for wiring.
The first Fresnel Lens date back to 1822 when a French physicist by the name of Augustin Fresnel wanted to make our bodies of water safer for sailors throughout the world. The Fresnel Lens originally were a type of compact lens created by Fresnel for lighthouses. A Fresnel lens replaces the curved surface of a conventional lens with a series of concentric grooves, molded into the surface of a thin, lightweight plastic sheet (“Fresnel Lenses”). The Fresnel Lens were beneficial for lighthouses because they have the ability to capture more oblique light which allowed lighthouses that used them to be seen from greater distances. Fresnel’s lens resembles a giant beehive with a complex system of multi-faceted glass prisms mounted in a brass framework.

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.
Heinrich Lamm was the first person to demonstrate image transmission through a bundle of optical fibers.

All forms of commerce will benefit from fibre optic connectivity as it will lower the cost of communication, which is a vital part of any business. New opportunity for the growth of the data market will emerge as cheaper bandwidth should translate to more users.
Coaxial cables may be rigid or flexible. Rigid types have a solid sheath, while flexible types have a braided sheath, both usually of thin copper wire. The inner insulator, also called the dielectric, has a significant effect on the cable's properties, such as its characteristic impedance and its attenuation. The dielectric may be solid or perforated with air spaces. Connections to the ends of coaxial cables are usually made with RF connectors.

Optical computing means performing computations, operations, Storage and transmission of data using light, instead of silicon chips. Optical computers are not completely discover. Optical, computing generally means that the optical manipulation of discrete manipulating data. The hope for optics lies in doing things that are provably impossible for electronics. This paper is consist of different types of optical computing (mainly digital analog and quantum), how the networks has been transported in optics (since 1990, SDH, and SONET specifications have been extended based upon the demand for the transport of new tributary signals and also based on new capabilities provided by the evolution in component technology), architecture of optical computing. Optical computing is safe for human use because of free from electrical short. The basic requirements of an optical computing architecture for information processing are: (i) optical sources (ii) input information for processing (iii) a method of modulating the sources to carry the input information and finally (iv) an information processing or decission making
