Optical Fiber Thesis: Some of the important characteristics of optical fiber that interest us are discussed below. Today we use copper wires as they are the cheapest and most reliable interconnection in parallel machines. However, as machines become more powerful, cable density becomes critical making alternatives to fiber possible due to the smaller size of the cables. Optical fiber is mainly used to effectively utilize its high bandwidth. On a single fiber it is possible to transmit numerous information/data simultaneously and in parallel. Over 1000 independent high bandwidth (100-200 Mb/s) channels or buses can be supported on a single optical fiber. Furthermore, multiple buses can coexist on a single fiber. Fiber links allow a series of high-speed serial links to replace large numbers of power lines. The use of fiber therefore saves space. The input and output properties of the fiber are very important. They give us an idea about the nature and functioning of fiber materials. Fiber cables can carry light signals from one place to another much like the way metal conductors carry electrical signals. Fiber cables guide light around bends and are capable of carrying light very long distances with minimal attenuation. But the transmission characteristics of fiber are not complete and completely efficient. Fiber cables introduce light loss and alteration of the modulation imposed on light signals to represent information. These distortion and delay attenuation effects limit the distances that can be covered without electro-optical repeaters and therefore limit the speed of information that can be transported even over long distances. Make fiber optic cables. It turns out that they can be made of just glass, glass plus polymers, or just polymers ("plastic optical fibers" -POF-). The most basic optical fiber consists of:a) An inner cylinder with a high refractive index, called a core.b) A central cylinder with a lower refractive index, called a cladding.c) An outer protective polymer layer (usually polyurethane or PVC) called the jacket. For glass optical fibers, the core diameter varies between 10-600 microns, the cladding thickness is between 125-630 microns, and the jacket thickness varies between 250-1040 microns. For POF all diameters vary between 750-2000 microns. As you can see, one of the......middle of paper......fiber cable fads.Saleim, M. (2000). Single-mode fiber cables. Optics Letters, 25(19), 1430-2. This source provides details regarding single-mode fiber optic cables. Here we study the details of single-mode fiber cables such as their brand, light path inside the core etc. Samuel, R. (1994). Fundamentals of fiber optics. New York: Wiley. This source provides details on fiber optic cable basics. We study the basic parts that make up optical fiber such as transmitters, receivers, fiber cable design etc. This gives me a good understanding of fiber optics, which will be important in my research work.

This source provides details about coaxial cables, their properties, their uses, etc. This study helps determine the types of cables suitable for a particular application. We can choose between fiber cable and coaxial cable. Wiseman, C. (2000). Fiber sheds light on many industries. Laser Focus World, 36(8),197-200.
