Abstract
This work establishes computational analysis of relative refractive index property for light transmission via fiber optics using MATLAB simulation. Optical fiber is a dielectric wave guide which transmits signal with a low attenuation and dispersion at higher bandwidth or data rate. Recent advances in fiber optics introduced a largely new dimension into optical technology with the effect of improving transmission through the application of cladding system. Cladding in fiber communication is importantly applied to ease light transmission in the fiber-core interface by total internal reflection at the boundary between two light propagation region of a typical fiber. Optical fiber communication is a well recognized aspect of optical light transmission where clad fibers of different refractive indices recount for a measurable Numerical aperture and Acceptance angle in fiber networking and communication technology. This has lead to the efficient and effective optical transmission due to the adequate emergence and utilization of optical properties and parameters in optical fiber applications. A double cladding was set for the fiber and a maximum relative refractive index of 2.000% is obtained for an acceptance angle and numerical aperture range of 59°-64° and 0.859-0.900 respectively. This implies fast light transmission, high bandwidth and small bending sensitivity for fiber networking with applications in medicine and telecommunication compared to single cladding fiber.

For signal transmission via optical fiber, modeling of refractive index profile is a strong and useful tool, for which its significant effects establish pronounced and suitable applications such as optical diagnostics, laser surgery, and signal networking
Relative refractive index has a maximum value of 2.000% between the two claddings at a minimum value of 0.859 numerical aperture
Relative refractive index has a maximum value of 2.000% between the two claddings at a minimum value of 64° acceptance angle
Summary
For signal transmission via optical fiber, modeling of refractive index profile is a strong and useful tool, for which its significant effects establish pronounced and suitable applications such as optical diagnostics, laser surgery, and signal networking. Since cladding optical fibers is vital to the finishing model of refractive index for fiber technology and its applications, this count for some varying optical parameters. Arbitrary refractive index profiling has been used to model optical fiber [8], refractive index and dispersion was determined for optical wave guides [6]. A lot of dispersion free and dispersion fibers is available in the market. This made optical fiber communication more advantages than conventional system.
