FIBER TO THE HOME: THE NEW EMPOWERMENT abstract: In order to offer future higher bandwidth applications‚ the choice for a fiber to the home (FTTH) network seems to be the best candidate. Still‚ as the full deployment of a new FTTH network involves tremendous civil works and costs‚ only the highly profitable areas‚ e.g. city centers‚ are currently being installed. With the installation of such FTTH networks‚ all involved parties stay with many questions. What will the future bring on demands from

HISTORY OF FIBER OPTICS * In 1840‚ Daniel Colladon and Jacques Babinet demonstrated the principle of guiding light by refraction. * It was followed by a public demonstration by John Tyndal in 1852. In 1870‚ Tyndal wrote about the property of total internal reflection in his book about the nature of light. * In 1880‚ Alexander Graham Bell and Sumner Tainter invented the Photophone‚ a device capable of transmitting sound waves over beam of light. This is considered as mankind’s first attempt

Fiber optic communication ABSTRACT FIBRE-OPTICS COMMUNICATION Most reference materials that discuss the historical perspective mention about Indian smoke signals. None of these primitive systems was secure due to the spreading of the unguided light. Ideally‚ a communication system should be secure and should not require installation of a cumbersome physical media. Fiber optics satisfied these desires‚ and as early as 1958‚ fiber-optic equipment was being focused for use in the factory. The fiber-optic

Cri Du Chat is a genetic disorder that is also known as chromosome deletion 5p syndrome and also monosomy 5p syndrome. When first discovered in 1963 it was recognized as a defective B group chromosome‚ and was then later recognized as the fifth chromosome‚ or 5p. Its name is French‚ and means “Cry of the Cat” referring to the distinctive cry of children with this disorder. This cry can help doctors make an informed guess as to whether the baby has the disease. Cri du chat is one of the most common

FIBER-OPTIC COMMUNICATION Introduction Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic waves that is modulated to carry information. First developed in the 1970s‚ fiber-optic communication system have revolutionized the telecommunication industry and have played a major role in the advent of the information over age. Because of its advantages over electrical

Copper vs Fiber Some advantages of Copper Cabling are Power over Ethernet this gives you the ability to power phones‚ surveillance cameras‚ Wireless Access Points‚ and many other devices right through the networking cable itself. That means that you don’t have to schedule an electrician in to run power to your surveillance cameras to power them. Another advantage is the ability to have an emergency power supply that will continue powering mission critical devices even if your electricity goes

Copper vs Fiber They are two major types of cables used in networking‚ copper and fiber. Each cable are used in different application regarding to its usage. They also have different strengths cause of the material they are made of. Copper is the most common out of the two cables. Not as powerful as Fiber‚ but are ideal for buildings up to 100m. Fiber is mostly used for longer distances that copper can’t reach. For example‚ Fiber is ideal for high-rise buildings. Both cables do have their weakness

And now‚ we have one more remarkable material – Coffee Fiber. Description Coffee fiber is a composite technical fiber from waste coffee grounds. This fiber is made into a yarn that can be knitted or woven fabric. The fabric‚ called “S.Cafe” is a result of over 3 years dedication and efforts of a Taiwanese company.
