Optical Fiber Seminar Report
The first communication of fiber optic start off by Alexander Graham Bell in 1880 called as The Photophone. The Photophone is a device that permitted for the transmission of sound on a beam of light. Based on the Photophone capabilities which can use of an atmospheric transmission medium, Bell creates the first wireless telephone transmission within two buildings with 213 meters apart. However, the Photophone was more practical and took tangible shape. It does not show any practical prove until the enhancement has been made and secured the transport of light was permitted in the technologies of laser and optical fiber.
The mode of optical fiber was first discovered by Harold Hopkins and Narinder Singh Kapany in 1954. They showed that light can be transmitted through the rolled fiber glass and since that it was considered that the light can traverse in only straight medium. In early year single-mode fibers had cores several micrometers in diameter, and after that its bothered developers. They were thought it would be possible to achieve the micrometer-scale

This is important to recognizing the weakness of optical fiber to avoid a user requirement meets the weakness. All the weakness of each type of optical fiber will be discussed as it will help in keeping user have a clear explanation. Firstly, not affordable by some people. Cost is the main weakness of optical fiber. It is more costly than copper even though consist of plentiful and low in price raw substance which is sand. The optical fibers are more costly to buy, they are more costly to install and need to fixed by the experts. They are not as vigorous as the wires, they have special trial equipment is frequently indispensable to the optical fiber and the installation costs are still high. Although, one fiber can bring numerous more signals than a single copper cable and the big transmission distances mean that less costly repeaters is

404 Words | 2 PagesIn half-duplex networks, the node transmitting must make sure that the network is quiet prior to transmitting, and in addition there is usually some mechanism for transmitting nodes to detect overlapping transmissions. 10BASE5 coaxial cable is the transmission technology used in the classic Ethernet protocol which was a stiff enough cable which was hard to install in buildings etc. as it was hard to bend. As it was hard to install along with other issues, 10BASE2 cable was made which was a skinnier coaxial cable which had obvious improvements in terms of installation.

804 Words | 4 PagesThe experiment used a light of a single color, or monochromatic light, and two closely spaced slits or pinholes. He realized that the bright fringes of light resulted from light waves from both holes arriving crest to crest, creating a constructive interference. He also realized that the dark areas resulted from light waves coming from trough to crest, creating a destructive interference. The interference fringes made were straight lines. This interference experiment demonstrated the wave nature of light idea generated by Huygens 200 years earlier.

831 Words | 4 PagesUnit D Summary: Light and Geometric Optics 10.1 : Light and The Electromagnetic Spectrum Chapter 10.1 covers light and the electromagnetic spectrum. This chapter starts off by describing how light is a form of energy that travels in waves. The properties of said waves include a crest (the highest point of the wave), the trough (the lowest point of the wave), and the rest position (the level of a wave without energy).

How Did The Market Revolution Change America
527 Words | 3 PagesThe telegraph improved American life and made it easier to communicate across long distances. This was very useful in business. It allowed loved ones to also assure their families that they were all right. Of course only a few words were allowed to be sent, but it was still useful. Telegraphs weren't nearly as useful as the telephone but that came in later on.
Compare And Contrast The French Revolution And The American Civil War
861 Words | 4 PagesAmerican civil war and Napoleonic conflicts Introduction There are questions as to whether the American civil war was the first modern conflict or it was similar to Napoleonic conflicts. The American civil war occurred between 1860 and 1865 and therefore, some scholars have argued that it was both the last ancient war and the first modern conflict. While the Napoleonic conflicts employed ancient tactics and strategies, the American civil war was the first conflict to employ the efficiencies of production occasioned by the industrial revolution. The war also involved the entire population of either side of the conflict .

1920's Inventions
807 Words | 4 PagesThese inventions changed the way that people interacted with one another. An example of this is the battery-less radio, created in 1925 by Edward Samuel Rogers. This invention was extremely helpful, as the radio could be plugged into a household electrical socket, opposed to requiring cumbersome batteries. The radio was so well regarded that it was considered “…The set that marks a new era in radio” (Freeman-Shaw, Haskings-Winner 47). This invention not only secured Rogers’ place in the history of communication technology, but also allowed more Canadians to have access to a radio, as anyone with household electricity could use it.

An analogue repeater can only amplify a signal, while a digital repeater can repair a signal to close to its original quality. The Software components which enable the internet access are: Operating systems – so that the PC is able to function with internet protocols and the ISP service. Browsers – so that the PC can reach and display HTTP links NON-essential internet access software: FTP software –File Transfer Protocol software is used to exchange files over the internet.

Newton's Rings Lab Report
1516 Words | 7 PagesThe plano-convex lens is replaced with another glass plate and a section of optical fibre was placed between them at one end. Light falling normally on the plates will be reflected back out with a phase difference. Figure 3: Apparatus set up for finding the thickness of an optical fibre, showing the optical fibre between the two glass plates This is due to the fact that some of the coherent light waves were reflected from the top plate and others from the bottom, this path difference resulted in the interference of these waves with one another. This caused an interference pattern similar to the below image: Figure 4: Image similar to the observed interference pattern.
