Optical FiberThesis:Some of the important features of optical fiber that interest us are discussed below. Nowadays, we use copper wires because they are the most cost-effective and reliable interconnection in parallel machines. . However, as machines become more powerful, yarn density becomes critical, making fibers possible as alternatives due to their small yarn sizes. Optical fibers are mainly used to efficiently utilize their high bandwidth. On a single fiber, a lot of information/data can be transmitted simultaneously and in parallel. More than 1,000 independent high-bandwidth (100-200 Mbps) channels or buses can be supported on a single optical fiber. Additionally, multiple buses can coexist on a single fiber. Fiber links allow a number of high-speed serial links to replace a large number 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 of ​​the nature and functioning of fibrous materials. Fiber cables can carry light signals from one location to another, in the same way that metal conductors carry electrical signals. Fiber cables guide light around bends and are capable of carrying light very long distances with very little attenuation. But the transmission characteristics of fiber are not complete and completely efficient. Fiber cables introduce loss of light and smearing of the modulation imposed on light signals to represent information. These distortion and delay attenuation effects limit the distances that can be traveled without electro-optical repeaters and thus limit the information rates that can also be carried over long distances. Made from fiber optic cables. It turns out that they can be made of only glass. , glass plus polymers, or simply 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 layer of polymer (usually polyurethane or PVC) called the cladding. For glass optical fibers, the core diameter is between 10 and 600 microns, the cladding thickness is between 125 and 630 microns and that of the sheath varies between 250 and 1,040 microns. For POF, all diameters vary between 750 and 2000 microns. As can be seen, one of the ......middle of paper ......the fiber cable mode.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 like their brand, light path inside the core, etc. Samuel, R. (1994). Fundamentals of fiber optics. New York: Wiley. This source provides details on the basics of fiber optic cables. We study the basic elements that make up optical fiber like transmitters, receivers, fiber cable design, etc. This gives me good knowledge about fiber optics, which will be important in my research work. Tom, N.H. (1995). Theory and practice of optical fiber. New York: McGraw-Hill. This source gives details about coaxial cables, their properties, uses, etc. This study helps determine which cable types are suitable for a particular application. We have the choice between fiber cable and coaxial cable. Wiseman,..
