Fiber optics
Thesis:
Some of the important features of the fiber optics that we are interested are discussed below.
Now a days we are using copper wires as they are the most cost effective and reliable interconnect in parallel machines. However as machines grow more powerful, wire density becomes critical making fiber possible alternatives because of their small wire size.
Fiber optics are used mainly to use effectively its high bandwidth. On a single fiber lots of information/data can be transmitted concurrently and in parallel. Over 1000
high bandwidth (100-200 Mb/s) independant channels or busses can be supported on a single optical fiber. Furthermore multiple buses can co-exist on a single
fiber. Fiber links allow a number of high speed serial links to replace a large number of electrical lines. The use of fiber is thus space saving.
The input and output properties of the fiber are very important. They give us an idea about the nature and working of fiber materials. The fiber cables can transport light signals from one place to another place just similar to the way the metallic conductors transport electric signals. The fiber cables guide light around bends and they are able to carry light for very long distances with very little attenuation. But the transmission characteristics of the fiber are not complete and completely efficient. The fiber cables introduce loss of light and smearing of the modulation imposed on the light signals to represent information. These affects of delay distortion and attenuation limit the distances that can be spanned without electro-optic repeaters and thus limit the information rates which can be carried over long distances as well.
Make of fiber optic cables.
Turns out they can be made of just glass, glass plus polymers, or just polymers ("plastic optical fibers" -POF-). The most basic optical fiber consist of:
a) An inner cylinder with high refractive index, called the core.
b) Middle cylinder with a lower refractive index, called the cladding.
c) An outer protective polymer layer (usually polyurethane or PVC) called the jacket.
For glass optical fibers, the diameter of the core ranges between 10-600 microns, the cladding thickness is between 125-630 microns, and that of the jacket varies between 250-1040 microns. For POF all diameters range between 750-2000 microns. As can be seen, one of ...

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:
To begin, the first instance of redemption is found and portrayed through irony. As Amir's mother died giving birth to him, he has always felt guilty. Leading up to the annual kite-fighting tournament, Amir feels as if winning will redeem her death, and solidify his relationship with Baba. When he comes upon Hassan who is cornered by Assef, Amir feels as if his rape might be justified: “Maybe Hassan was the price I had to pay, the lamb I had to slay to win Baba. Or was it a fair price?” (Hosseini, 82) If Amir gains the kite, he wins Baba's heart. Ironically, the sacrifice of Hassan is the catalyst to Amir's need for redemption. Instead of redeemi...
... Kites are symbolic in the novel as it helps to support the themes of guilt, redemption and freedom in the novel. In the beginning of the story, Amir overhears Baba telling Rahim Khan that if Amir could not stand up for himself, he would never be able to stand up to anything when he becomes a man. It takes Amir over twenty years to finally muster up enough courage to stand up for himself in front of Assef. Amir takes the beatings from Assef as his punishment for what happened to Hassan. He rescues Sohrab and bonds with him through kite fighting, similar to when he flew kites with Hassan. Kites represent the freedom from the worries and burdens that Amir, Hassan and Sohrab has. It brings together the two participants in kite fighting. It gets rid of the discrimination of the ethnic caste system, any cultural differences, and also emphasizes unity amongst difference.
In this two part lab we are to build a spectroscope from parts included with our lab kit to visualize and analyze the spectra of several light sources. In the second part of the lab we are to build a pinhole viewer. We are to then take the pinhole viewer and measure the diameter of the sun and moon. After completing both parts of the lab, there are several questions that need addressing. This paper examines and answers those questions.
...a kite for Amir to put a smile on his face, and now that Hassan passed away, Amir is left with Sohrab who he repeats the same action with. In a way Amir did not truly find redemption as he was only trying to free himself from the consequences of sin rather than change for the better. In conclusion, redemption is so important because it frees a person from the sin and suffering they have endured.
In affluent school districts which in most if not all cases are predominantly white students have “the best teachers, most up-to-date textbooks and computers, and superior academic facilities.” School districts made up of mostly wealthy and white students have the money to pay for superior resources and staff. However, struggling schools in equally struggling school districts do not have the money to pay for better resources and staff to improve the education of economically disadvantaged and racial minority students. Students inside of these economically disadvantaged school districts are left at a large disadvantage when it comes to competing for a higher education with wealthy white students with a high quality education. These disadvantaged students are left to fend for themselves without the support system and quality resources that are afforded to wealthy white students when looking for future opportunities such as applying for college. African Americans and other minorities restricted from buying homes and building equity has kept them in a state where they have little to no chance to improve their condition. Even if the people in low-income neighborhoods are very talented and have a large amount of potential they have no way to exercise and build on that potential because they don’t have an opportunity to attain an
Refraction of Light Aim: To find a relationship between the angles of incidence and the angles of refraction by obtaining a set of readings for the angles of incidence and refraction as a light ray passes from air into perspex. Introduction: Refraction is the bending of a wave when it enters a medium where it's speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. The amount of bending depends on the indices of refraction of the two media and is described quantitatively by Snell's Law. (Refer to diagram below)
The exercise completed above emphasized how to appropriately identify communication techniques and phases of interaction. The format for a therapeutic conversation stressed the importance of a therapeutic relationship with the client. Therapeutic relationship is defined as “a professional, interpersonal alliance in which the nurse and client join together for a defined period to achieve health-related treatment goals” (Arnold & Boggs, 2015, p. 181). The appropriate skills acquired to achieve a therapeutic relationship is important as it elicits focused-patient care, and allows the client to be educated and be properly informed of what is happening at the moment. The conversation addressed several things that influenced the communication with
Fiber optics is a new technology that uses rays of light instead of electricity to transmit information over optical fibers at very high speeds. The optical fibers are usually thin strands of glass that are combined into cables and used to send information and computer data in the form of pulses of light. The optical fibers provide much clearer transmission than conventional copper cable and satellite links. The world market for optical fiber continues to grow rapidly, with shipments increasing 14 percent from an estimated 7.0 million kilometers of fiber in 1990 to approximately 8.0 million in 1991. The demand for multimode fiber is predicted to continue to expand through the mid-1990s, with some market analysts indicating that 15 to 20 percent annual growth over the next three years is reasonable. Strong demand is expected for singlemode and multimode fiber to be used in cables for local area networks, telecommunications, cable television (CATV), and transoceanic fiber-optic systems.
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.
The concept of fiber optics is simple, yet it provides so many potentialities in the world of technology. Presently the world relies on fiber optical technology for its data and communications systems. The consumer can converse on the telephone and hear voices with clarity, as well as send and receive information on the Internet with ease. However, there still lay a sea of possibilities in this area of technology that has not yet been discovered.
...MEMs design, I hope to advance my understanding. Through research at the graduate level, it is my hope to become familiar with, and innovate the design of MEMs Optics in hopes of creating a reliable and practical MEMs Electro-Optical Interface for use in consumer electronics. It is my hope, that through my research, optical waveguides for intradevice communication might be realized.
Currently, relatively few urban poor students go past the ninth grade. The graduation rates in large comprehensive inner-city schools are abysmally low. In fourteen such New York City Schools, for example, only 10 percent to 20 percent of ninth graders in 1996 graduated four years later. Despite the fact that low-income individuals desperately need a college degree to find decent employment, only 7 percent obtain a bachelors degree by age twenty-six. So, in relation to ...

Li-Fi may solve issues such as the shortage of radio-frequency bandwidth and is aimed at creating new communication channel with the use of existing equipment. The concept of Li-Fi is currently attracting a great deal of interest, not least because it may offer a genuine and very efficient alternative to radio-based wireless.
