1ENGINEERING PROJECT PREPARATIONExecutive SummaryIn a communication system, the optical fiber is considered as the most critical media forcommunication. It is used for transmitting high-speed data as it is versatile and there is negligibleloss during transmission. The optical fiber is widely used for the development oftelecommunication as it supports communication over long distance. However, there is anexistence of dispersion. Hence, it is essential to understand the types of dispersion and test theexistence of dispersion in the optical fiber. In multimode fiber, a noteworthy part is played bymode dispersion though, in single mode fiber, the fundamental system is chromatic dispersion orintramodal dispersion. In this paper, another estimation technique for chromatic dispersion hasbeen proposed for the higher-arrange methods of an optical fiber with the assistance ofFrequency Modulated Continuous Wave (FMCW) interferometry. In single mode fiber,dispersion occurs as bottleneck in optical communication systems where transmission of dataoccurs for long term. This results into limitation on bit rate as well as repeater-less distance.

3ENGINEERING PROJECT PREPARATION1. IntroductionAn optical fiber is only a variable fiber of clear glass powerful at conveying informationas light. Optical materials are hair-thin structures made by framing pre-shapes, which are glasspoles. Few-mode optical fibers (FMFs) which are also referred to as higher order mode fibers,have already been versatilely used in several purposes for dispersal settlement in long-haultransmission systems (Leo et al. 2013). It is important to conduct mode analysis along withmeasurement of chromatic dispersion in context to FMF such that the performance of the opticaldevices and sensors can be upgraded.Hence, this study will be conducted to propose anestimation procedure to measure the chromatic dispersions existing in optical fibers. It will beaccomplished with the help of a Frequency Modulated Continuous Wave (FMCW)interferometry by using a tunable laser and a straightforward interferometer.2. Literature Review2.1 Overview of dispersionDispersion is depicted as heartbeat disseminating in an optical fiber. As a beat of gentlespreads through a fiber, segments, for example, numerical gap, the essential distance across,refractive list page, wavelength, and laser point width make the beat expand. Dispersionincrements over the fiber length. The general effectuation of dissemination on the execution of afiber optic process is known as Intersymbol Disturbance (ISI) (Temprana et al. 2015).Intersymbol impedance happens when the beat disseminating caused by conveyance triggers theprofitability beats of a framework to cover, rendering them imperceptible. Dispersion is typicallydivided into three types: modal distribution, chromatic distribution and polarization functiondispersion.
