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 of fibre optics is high resolution visuals (HDTV) which

------------------------------------------------- ABSTRACT The race for unprecedented bandwidth is on - and DWDM(Dense Wave-length Division Multiplexing) is opening the way. DWDM is the technology that allows multiple streams of data to flow in one optical fiber of optical communication network. DWDM is the key technology at the heart of new systems and networks that offers more bandwidth at less cost. Soon‚ DWDM promises to change bandwidth from a premium to a commodity item. DWDM: Networks‚ Devices‚ and

predates optical fiber and has its roots in wartime efforts to develop secure communication systems that did not require cable and could withstand radio jamming. FSO has been around for more than a decade‚ but it is only recently that interest in this technology has started to grow. Free Space Optics (FSO) communications‚ also called Free Space Photonics (FSP) or Optical Wireless‚ refers to the transmission of modulated visible or infrared (IR) beams through the atmosphere to obtain optical communications

Chapter 1 Introduction 1.1 History of Free Space Optics Even though fibre-optic communications gained worldwide acceptance in the telecommunication industry‚ FSO communications is still considered relatively new. But optical communication‚ in various forms‚ has been used for thousands of years. The Ancient Greeks polished their shields to send signals during battle. In the modern era‚ semaphores and wireless solar telegraphs called heliographs were developed‚ using coded signals to communicate

RAM RAM is an acronym for Random Access Memory that is also known as volatile memory‚ because the data it holds is lost when the desktop PC or laptop/notebook computer using it is switched off. Briefly‚ RAM memory is used by the system to store data in the form of files for processing by a computer’s central processing unit (CPU)‚ also known as the processor. The amount of RAM memory used in modern desktop and laptop computers is expressed in megabytes (MB) and gigabytes(GB). A gigabyte (1GB)

Backbone Cable: Backbone Cabling is the inter-building and intra-building cable connections in structured cabling between entrances. 3. Patch Cords: Insulated cord with a plug at each end‚ for use with a patch panel. 4. Connectors: Cable connectors are devices for keeping two parts of an electric circuit in contact. 5

Optical Distortion‚ Inc (ODI) is a company that has developed special contact lenses to harmful impact the eyesight of egg-laying chickens. The reduced vision from the contact lenses helps preserve the life of chickens‚ increase the productivity of egg laying and reduce costs for farmers using the lenses for their flocks. At the end of 1974‚ ODI’s owners and management were finalizing a strategic marketing plan to introduce the lenses commercially early in 1975 and work towards nationwide penetration
