The horizons of optical networks are much more than high speed physical layer transport. An intelligent optical network design must include higher network layer considerations. This is the only book currently on the market that addresses optical networks from the physical layer to the network layer and should be valuable for those who try to understand the intricacies of what optical networks can be. —Vincent Chan‚ Professor‚ MIT Department of Electrical Engineering and Computer Science This book

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

Illusion of the American Dream The American Dream has been an idea that everyone has their right to happiness‚ and the utmost standard of living. The dream suggest that everyone should have equal opportunities as long as that individual works hard for what they want. But it seems as if some individuals are more fortunate to gain what they specify as the American Dream‚ while others are not. What is so special about the American dream is that it varies from person to person. Individuals can believe

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

Technology Devices to Overcome the Limitations of Sight and Hearing Humans have sight and hearing limitation. Without any devices‚ our sight and hearing was limited. Most of the limitation of sight can be overcome with the help of certain optical instruments such as magnifying glass‚ microscope‚ binoculars and others. The range of frequency of hearing in human 20 Hz to 20 000 Hz. It was different according to the age of a person. Hearing limitations can be overcome by using devices such as

surrounded by a twisted braid‚ foil or both and bound in a single plastic sheath containing balanced twisted-pair conductors that are individually shielded. Fiber-optic Cable- is a cable made up of optical fibers that can transmit large amounts of information at the speed of light. Dark Fiber- is an unused optical fiber available for use in fiber-optic communication. Coaxial Cable- a cable that consists of a center wire surrounded by insulation and then a grounded shield of braided wire. Plenum- a compartment

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)

considered noise or interference and is expressed in decibels. 2. Waveguides – A structure that guides electromagnetic waves along their length. The core fiber in an optical-fiber cable is an optical waveguide. 3. FTTH – (fiber-to-the-home): Fiber reaches the boundary of the living space‚ such as a box on the outside wall of a home. Passive optical networks and point-to-point Ethernet are architectures that deliver triple-play services over FTTH networks directly from an operator’s central office. 4. Simplex

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
