This thesis describes different index profiles and types of dispersion and how these factors contribute to light propagation in an optical fiber. We confront different obstacles and problems, which prevent the implementation of multimode fibers that operate at longer wavelengths. Manufacturing these types of fibers is a key way to improving the communication systems, which we will prove during the course of this paper.
For easier understanding, It is important to familiarize ourselves with the basic concepts of optic communications. To understand light propagation and the effect of attenuation of an optical fiber is key for further comprehension. A big influence on performance and efficiency of an optical fiber is It's manufacturing process, where we need to acquaint ourselves with different types of chemicals procedures and materials. We confront the problems of light propagation, different profile shapes, types of dispersion and the possibility of implementing multimode fibers at longer wavelengths with different equations and detailed descriptions of simulations.
We concur, that the implementation of these fibers is indeed possible with the use of algorithms and different equipment. Implementation of systems that use multimode fibers that work at wavelengths ranging from 1300 to 1550 nm would be a step in the right direction, because they are more efficient and cheaper to install than singlemode fibers.
