Fibre Optics Technology over the past century has advanced greatly. Fibre optics however is being utilized since more than a hundred years. Optical fibre is a model that has evolved greatly over time. From guided transmission lights experiments to lasers and light emitting diodes (LED)‚ and to dense wavelength-division multiplexing (DWDM)‚ the area under which optical fibre can be used has expanded. One of the modern and commonly used applications

PC TO PC FIBER OPTIC COMMUNICATION [pic] Submitted By: lex INTRODUCTION DEFINITION The project PC to PC fiber optic communication deals with data transfer from one computer to another. It uses C programming and the serial ports of the PCs. The ports are programmed in C. We use MAX 232 to convert RS 232 logic to TTL logic and then an optical transmitter circuit to transmit data via fiber optic cable. The optical transmitter circuit has a LED which is matched as far the cable

The Impact of Internet on Our Society Wong Yiu Cheung The emergence of the Internet allows people in all over the world to share the information by connecting computers together. Its development has reached to carry the large numbers of data that we have not imagined before. It also brings impact on the real life by creating brand new tools‚ platforms‚ and attempts to satisfy people’s wants only when they are holding a device that can access to the Internet. The impacts are both positive and

Impact of Computers On Society 2010 The concept of a computing device was there since the 19th century but the actual device was not invented until the 1930s. The computers invented at that time served as a project to simplify scientific calculations and they fulfilled that task quite perfectly. Later on these were used to store data such as the process and calculations. At that time‚ people knew that this device was something which will never die like every important invention does for eg

The impacts of hooliganism on our society Firstly‚ we started discussing the topic of hooliganism throughout the world and also in our country. We have watched many videos on the Internet‚ investigated further and interviewed many people all around the world with many different perspectives. Furthermore we paid attention to the problems that hooligans make and imposed different solutions to this problem. But first of all we answered questions we had primarily stated in project plan so we can understand

Fiber Optics Assignment Many modern medical materials and equipment work on a principle which is beyond the capacity of human transducers. Comment and discuss the working principles of an endoscope‚ uteroscope or a rectoscope showing the illuminating path‚ the image path‚ transmission path and the liquid transfer or operating instrument ducts‚ showing the position of suitable valves. This will therefore explain how light travels through an optical fibre and show how such

1 Unit – 4 Engineering Physics OPTICS Dr. V.P.N. Padmanaban M.Sc.‚ Ph.D.‚ Associate Professor 1. Interference Interference of light waves is a superposition phenomenon. This phenomenon was first described by Thomas Young in 1801. It provided strong evidence for the wave theory of light. In Young’s interference experiment‚ an incident monochromatic light is diffracted by a slit in the first screen‚ which then acts as a point source of light that emits semicircular wavefronts. It is
