times. Communication plays an important role in human beings life. Optical fiber has modernized the way the world communicates. Optical fiber is a combination of light and glass, build in a strand of glass thinner than human hair. This astonishing medium allows us to broadcast data, voice and video at the speed of light. Researchers who were working for American Glass maker Corning Incorporated invented the first low - loss optical fiber with crucial attenuation limit of 20 db/km for use in telecommunications
Optical Fiber Corporation SWOT ANALYSIS Environment Fiber optics is a new technology that uses rays of light instead of electricity to transmit information over optical fibers at very high speeds. The optical fibers are usually thin strands of glass that are combined into cables and used to send information and computer data in the form of pulses of light. The optical fibers provide much clearer transmission than conventional copper cable and satellite links. The world market for optical fiber
Optical Communication Optical communication is defined as a communication in which light carries signal from one end to another. Optical communication depends on optical fibers to carry out the signals to the other end or to the destination. Optical communication has three building blocks transmitter, receiver and medium. Optical fibers are used as transmission medium. Advantages of Optical communication/Optical fiber: • Optical Fiber Cables can run long distance like 40KM, without repeating. For
computing today is limited less by the computer’s performance than by the rate at which data can travel between the processor and the outside world. Fiber-optic solutions are replacing copper-based solutions, which can no longer meet the bandwidth and distance requirements needed for worldwide data communications [3]. Over the last decade, optical communication technologies have migrated steadily from long-haul backbones to the network edge, invading metropolitan area networks (MANs) and campus-level
send signals from point to point, however, given that glass was a brittle substance, any fibres that he could produce would break easily. In September 1959 DiVita asked 2nd Lt. Richard Sturzebecher if he knew of a way to produce a strong glass fiber that would be capable of carrying a light signal. Sturzebecher had melted 3 triaxil glass systems together for his senior exam at Alfred University. In his exam, Sturzebecher had used SiO2, a glass powder produced by Corning. Whenever he had tried
Surface plasmon resonance sensor is a promising optical sensor. In 1902, Wood discovered that there are loss of small area in the spectrum after the light beam passed through a grating[4]. This discovery has been intensified by many researchers. Until 1971, Kretschmann used a prism as a substrate and covered its bottom with thick metal film to achieve SPR detection [5]. Thereafter, SPR technology achieved great development. According to Liu and his colleagues in 2013, this prism based SPR sensor
The Nature and Propagation of Light In order to understand how the light propagates across the optical fiber, it is important to understand the nature of light and how it propagates. The Nature of Light The scientists were confused about what light really is. Three main theories were evolved to understand what is light. 1- Light as rays "In the classical physics that many of us learned at school, light consisted of "rays” that could be reflected and refracted through mirrors and prisms etc. This
Fiber optic communication has become necessary have to most of the big multinational companies and government agencies. Heavy investments have taken place in regards to this particular type of communication. Form the developed countries to the developing countries fiber optic communication has become the preferred means of data transmission. The following report will look at Fiber optics and fiber optic communications critically. The history of the fiber optics will be liked into as well as the basic
Introduction There are the two main approaches used in optical multiplexing. One is optical wavelength division (frequency division) other is optical time division Multiplexing. This paper deals with optical time division Multiplexing. In optical time division Multiplexing (OTDM), a high bit rate streams constructed directly by time multiplexing several lower bit rate. At the receiver end of the system very high bit rate data streams demultiplexed into the lower bit streams before detection and
life of people. The aim has become to control the optical properties of materials. A massive range of technological developments become possible by engineering of such materials that respond to light waves over a desired range of frequencies. They can perfectly reflect the light waves, or allow them to propagate only in certain directions, or can also confine them within a specified volume [1]. The introduction of components such as optical fibers or integrated ridge waveguides which were based on
Introduction: Scientists and engineers have been able to enhance our lifestyles by understanding and using the Laws, Concepts and Principles of Optics and how they are applied in Optical Instruments. The key concepts are: a. Lights as a form of electromagnetic radiation Electromagnetic radiation is a term used to describe a pair of electric and magnetic fields that promulgate together at the speed of light. This means that light holds electric and magnetic components. The accelerated movement of
Internet: The Internet is made up of thousands of computers from around the world, these computers are linked up together though cables and satellites. Often people think the Internet is a “cloud,” but it’s a physical object. It is made up of servers and clients, which are usually made out of plastic and metal, containing a series of electronic circuits, for example; wires, glass, fibre optics, chips and other simular parts to used make a circuit. The Internet is used for a wide range of activities;

Some of the tasks that someone working as an optics or photonics specialist might conduct include assembling, measuring, testing and repairing optical components; such as lenses, lasers, and light-emitting diodes (LEDs). Other tasks involve product development, as well as research and development. The jobs of optics and photonics specialists are becoming increasingly more important today, as
Fiber analysis has been used by law enforcement for many years in order to obtain evidence during investigations and also to place suspects at the scene of the crime. There is no set procedure for employing the use of fiber analysis however, it usually involves the examination of cross sections of a fiber under microscope. Additionally other tests such as the burn test and solubility test may be used to identify a fiber. Fiber transfers occur between people, people and objects, and objects and other
In this part of the assignment I am firstly going to explain the effectiveness of Wireless Communication, its advantages and disadvantages. This will include the different types of Wireless technologies and how they will make transmitting data easier or harder than ever. Also I will talk about Wired communication which is one of the older technologies but now we have several different types of media forms on wired communications and they all do a different job. Wireless Technologies could be satellite
What is Telecommunications? Telecommunications enables people around the world to contact one another, to access information instantly, and to communicate from remote areas. It usually involves a sender and one or more recipients linked by a technology, such as a telephone system, or computer network (LANs or WANs), that transmits information from one place to another. Devices used for telecommunications can convert different types of information, such as sound and video, into electronic signals
The Speed of Light Through Perspex Planning Light travels at different speeds through different mediums. The speed of light in air is 300,000,000m/s. When light enters an optically denser medium, it bends towards the normal (refracts). You can work out the refractive index of by dividing the sine of the incidence angle by the sine of the angle of refraction and then working out the ratio of the two. Sine i Sine r From this refractive index you can work out the speed of light through
Sphere Sphere is an interesting story about a group of scientists from different disciplines who are brought to a super-secret underwater site where the U. S. Navy has discovered a mysterious, glowing sphere. Although the movie was very interesting, a lot of scientific facts, it was just too long and there were parts of the film where I found myself yawning. I give the movie a thumb up for being the movie my teacher chose to show the class. Although the movie was directed by Barry Levinson and
