FIBER OPTIC 2 1.0 Introduction 1.1 Definition, Description, and Background Over a period of time aircraft communication have developed a need to create a bandwidth for both aerospace and onboard networking of their aircraft. There are two types of cables used in aircraft communication: standard coaxial cables and fiber optic cables, however, traditional wire cables have been replaced by fiber optic cables. Fiber optic cables use a wave of light in a transmission of the communication. Optic cables are light and produce a wide bandwidth as compared to wire cables. 1.2 The Purpose of the Report, Thesis Question, and Intended Audience The development of optic fibers is expensive. Evidence has shown that to produce aircraft that uses optic fibers is highly costly as compared to standard coaxial cables. However, the significance of optic cables has outweighed that of standard coaxial cables and in that case, there is a need for more development and research on optic fibers for a better tomorrow.What should be done to improve science, study, and development of optics? The objective of this study is to show the use of optic fibers in avionic line maintenance. 1.3 Method of Inquiry – Type of Report It's a semi-technical report that explains the usage and advantages of fiber optics in the avionics industry that is used in the aerospace world 1.4 Limitations of the Study From early source by John, C. (2012). Introduction to Fiber Optics. Amsterdam: Newnes. To the most recent by Caren B. Les, c. (2016). Fiber optics in avionics: Upward bound. Photonics.com.

FIBER OPTIC 3 2 Communication Systems Used in Avionics (Rise, types, and development) 2.1 History of development of communication systems in avionics The invention of telegraphy and telephony is one of the most significance inventions to communication (James, 2013). The communication system using optics date back to the period around 1790.This was the invention of optical semaphore the telegraph by Claude Chappe who was at the time a French inventor. This was made possible by the design of an electric battery by Volta in 1799 which led to the rise of an electric telegraph in 1837 by Morse. Morse developed binary digital communication systems in which English alphabets were encoded into binary elements having corresponding variable length code words (John, 2012). A sequence of dots and dashes represented the English alphabets. This representation was termed as code words. In this code, letters which were occurring in a less frequent manner were represented by long code words and those that occur more frequently were represented by short cord words. This was later developed into fixed code binary words of five. The significant aspect of telephony was the installation of the first transatlantic cable which link Europe and United States (James, 2013).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
