NT -1310 Unit 7 Assignments MAX HANEY 11/3/2014 Physical Networking Unit 7 Assignments Exercise 1 – Fiber Optics Definitions 1. Crosstalk – The coupling or transfer of unwanted signals from one pair within a cable to another pair. 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 4. Simplex – a. A link that can only carry a signal in one direction. b. A fiber-optic cable

through the slit. B. Law of reflection Angle of incidence is the angle formed by a ray incident on a surface and a perpendicular to the surface at the point of incidence. Angle of reflection is the angle between the reflected ray and the normal ray. The bean was seen and reflected from 10~40 degrees by 10 degrees interval from left and right. In this case‚ the plane of incidence is made by the incidence ray and reflection ray. The reflected ray is in

NT1310 Unit 7 Exercise 1 1. Crosstalk: A disturbance caused by electromagnetic interference‚ along a circuit or a cable pair. A telecommunication signal disrupts a signal in an adjacent circuit and can cause the signals to become confused and cross over each other 2. Waveguides: A circular‚ elliptical or rectangular metal tube or pipe through which electromagnetic waves are propagated in microwave and RF communications. The wave passing through the medium is forced to follow the path determined

Free Light Refraction Electromagnetic radiation
Refraction of light in water Refraction is the change in direction of a wave due to a change in its transmission medium. Due to change of medium‚ the phase velocity of the wave is changed but its frequency remains constant. This is most commonly observed when a wave passes from one medium to another at any angle other than 90° or 0°. Refraction of light is the most commonly observed phenomenon‚ When light travels from air into water‚ it slows down‚ causing it to change direction slightly. This
