Fiber Optics is the Future Tech Talk Advisory: I saw this video and it got my inner tech geek all excited. by Rothalack 6 months ago http://www.gameskinny.com/d3nr8/fiber-optics-is-the-future FDDI stands for Fiber Distributed Data Interface. FDDI uses optical fiber to distribute its data. Standard FDDI will run at 100Mb/s. FDDI is not regularly used because of how expensive it is‚ but offers many advantages that might make you think otherwise. The first and I think most important is the

Refraction and Snell’s Law When an ultrasonic wave passes through an interface between two materials at an oblique angle‚ and the materials have different indices of refraction‚ both reflected and refracted waves are produced. This also occurs with light‚ which is why objects seen across an interface appear to be shifted relative to where they really are. For example‚ if you look straight down at an object at the bottom of a glass of water‚ it looks closer than it really is. A good way

Examining the Refraction of Light in Prisms Questions 1. What is the relationship between the angle of incidence and the angle of refraction? The angle of incidence (formed by the ray of light travelling though air into a slab of rectangular perspex) is not directly proportional to the angle of refraction (angle formed between the ray travelling though perspex and the normal). The graph of the plotted angles of incidence against the angles of refraction is not a straight line and therefore demonstrates

RESUME Units of area = cm2‚ ft2 Units of volume = cm3‚ ft3 Type of wave: heat‚ sound‚ magnetic‚ light. -All waves carry energy from one location to another Sound waves (acoustic waves): Travels through a medium Are mechanical Are longitudinal Generally travels in a straight line Are best described as a series of compressions and rarefactions. Diagnostic ultrasound: uses mechanical

THE LATEST TRENDS IN TELECOMMUNICATIONS Week 5 NTC/360 Network and Telecommunication Concepts May 14‚ 2005 FIBER OPTICS IN OUR SCHOOLS Fiber optic refers to the medium and the technology associated with the transmission of information as light impulses along a glass or plastic wire or fiber‚ about the thickness of a human hair. Fiber optic wire carries much more information than conventional copper wire‚ and is far less subject to electromagnetic interference. A single glass fiber

Advantages and Disadvantages of Fiber Optics An optical fiber is a thin and flexible fiber that carries the light between the two ends of the fiber. Optical fibers are widely used in Fiber Optic Communications‚ which is the transmission over longer distances at higher bandwidths than other communications. A fiber optic communication system consists of three components: an optical transmitter‚ a fiber optic cable‚ and an optical receiver. The optical transmitter converts electrical signal to

Spherical Mirrors A spherical mirror is a mirror which has the shape of a piece cut out of a spherical surface. There are two types of spherical mirrors: concave‚ and convex. These are illustrated in Fig. 68. The most commonly occurring examples of concave mirrors are shaving mirrors and makeup mirrors. As is well-known‚ these types of mirrors magnify objects placed close to them. The most commonly occurring examples of convex mirrors are the passenger-side wing mirrors of cars. These type of mirrors
