Essays on Optical Fiber

Raman spectroscopy is dependent on scattering of light. When light interacts with matter, energy exchange can take place through absorption, simulated emission, Raman scattering or spontaneous emission. In Raman scattering, the emitted photons have less energy and lower frequency in comparison with the absorbed photons. Some energy of the emitted photons is transferred to the molecules. Raman spectroscopy is a method which collects the chemical fingerprints associated with molecules. Every molecule has different levels of vibrational energy and the emitted photons experience shift in their wavelengths. The wavelength shifts are collected,examined and analyzed for sample identification. Raman spectroscopy ...

PURPOSE: APPARATUS: Fiber optics of various lengths Trainer boards Function generator and LED Circuits Radio Wood board and tape Reflective Material Paper Ac voltmeter Cables INTRODUCTION: Fiber optics refers to a field of study under both engineering and applied sciences. It deals with the designing and usage of optical fibers. The fibers are flexible and transparent manufactured through the drawing of plastic or silica (glass) to diameters slightly greater than those of human hairs. Most often, optical fibers serve in the transmission of light between the two fiber’s ends. They find a wide use communications since they can ...

Introduction

The fiber optic systems are systems which use light as a mode of communication. The system includes fiber cables which allow for the transmission of light through them. Inside the cable are special coatings for protection and also to enable the transmission of light through total internal reflection (Hoss and Lacy). The light is then converted into electrical signals through the use of light detectors having in mind that the signal was produced by a light emitting diode. The use of optics is very wide since the use of light is much more efficient and also flexible being that ...

Introduction

21st century is the age of connectivity, a fast, smooth and convenient internet and other means such s 3G and 4G to address the ever-increasing connectivity demands. To cope with such demands, various operators have shifted from the age-old copper made wires to the sophisticated optic fiber based cables. The reason is that optic fiber allows more data to travel in a single pass, and it is easy to deploy. Furthermore, optic fiber allows much hedger speeds to cope with ever-increasing challenges in connectivity and entertainment sources. It is however; however, shifting from vintage copper wire to an optic fiber is ...

What do accountants mean by a Business Model, and how does this definition differ, if at all, from that of Teece (2010)? Katherine Schipper, talks about business model from an accountant´s point of view, saying that the business model is the use of several transactions of goods and financial resources looking after a profit motive. In ...

INTRODUCTION

The internet is termed as a revolutionary change in every society because of the technological and societal changes it brings about. The ease of access and exchange of information has become a phenomenon that is replacing old concepts. Companies are outsourcing their services to companies located overseas through the internet. The place and time of working has been greatly impacted by the internet. People work from the comfort of their homes at any time of the day and night possible through improved internet connectivity thanks to technologies such as fiber optics. The paper will review some of the current fiber optic ...
