Answer: A fiber optic cable is about as big around as a human hair but can carry more information than a much larger electrical wire. The first fiber optic semi-flexible gastroscope was patented by Basil Hirschowitz, C. Wilbur Peters, and Lawrence E. Curtiss, researchers at the University of Michigan, in 1956. (B) the loss of power due to defective components. History of Fiber Optics. As a pulse of light propagates through a fiber, elements such wavelength, and laser line width cause the pulse to broaden. You have to select the right answer to the question. With regard to the radar, if the pulse width (PW) is increased (with no change in the PRF), the meteorological target will likewise receive more energy over a given period of time. PART 1: MCQ from Number 1 – 50 Answer key: PART 1. ans: b. reliability 26. It is said to be the fastest among the other kinds of cables like STP cables and co-axial cables. In addition, sections on data communication and the internet, high-definition television, and fiber optics have been updated in this edition to enable readers to keep pace with the latest technological advancements. The macroscopic bending losses show an exponential increase due to _____ in radius of curvature. These changes were taken up and added to the newer fiber optic link specifications found in the 10BASE-F standard (described later in this section). Optical fibers are usually used in telecommunication services like internet, telephone, and television. Fiber optic systems are superior to … 50. A. The AFM was invented by Binning, Quate and Wang in 1986. Optical fibers are made from either glass or plastic.
