1. List the basic elements of a Fiber-Optic communication system • A fiber optic transmission strand that can carry the signal. • A source of invisible infrared radiation modulated to impress digital data or an analog signal on the light beam. • A photosensitive detector to convert the optical signal back into an electrical signal at the receiver. • Optical connectors at the light source-to-cable interface and at the cable-to-photo detector interface. 2. List Five advantages of an optical

"A carbon fiber is a long‚ thin strand of material about 0.005-0.010 mm in diameter and composed mostly of carbon atoms. The carbon atoms are bonded together in microscopic crystals that are more or less aligned parallel to the long axis of the fiber. The crystal alignment makes the fiber incredibly strong for its size. Several thousand carbon fibers are twisted together to form a yarn‚ which may be used by itself or woven into a fabric. The yarn or fabric is combined with epoxy and wound or molded

Is it ever morally permissible to lie to someone? Describe a circumstance in which it seems that lying might make more people happy than telling the truth. Would lying be the right thing to do in that circumstance‚ or is it our moral duty to tell the truth‚ even then? I believe in some causes it is morally permissible to lie‚ but in only if no one is in danger or if telling a lie could prevent harm to someone. At Christmas time we had an angel tree for the youth of our church‚ my aunt happened

Legal Defenses CJS 220 February 7‚ 2014 Selena Small Legal defenses are the reasons that a convicted individual uses in hopes of not being punished nor being responsible for a crime. According to the text‚ there are ten general legal defenses. The ten legal defenses are infancy‚ insanity‚ self-defense‚ intoxication‚ prevention of a violent felony‚ mistake of fact‚ necessity‚ entrapment‚ coercion‚ and syndromes (Meyer and Grant 2003). Infancy is one of the ten general legal defenses

| Refining Solutions It is essential to refine ideas and solutions to find the highest quality solution to a problem. The creative thinking process is used to produce ideas but the critical thinking process is used to evaluate and refine ideas and solutions. Applying criticism to ideas and solutions reduces the risk for error and makes good ideas even better (Ruggiero‚ 2009). In this paper Arguments will be evaluated and revised resulting in a refined and final solution to the problem. Original

creativity of fiber optic module packaging engineers as they endeavor to develop and mature new active and passive single-mode fiber optic and photonic components for next generation avionics networking applications. Low sales and manufacturing volumes inherent to avionics combined with lack of standard interface specifications for current and next generation fiber optic local area network architectures and sub-systems makes it difficult for avionics suppliers to justify upfront research and development
