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 or cord carrying a single fiber. Simplex cordage is mainly used for

performance issues because of dirty fiber end faces‚ excessive gaps between fibers or improperly installed connector offsets of fiber cores when mated. Modal Dispersion also known as angle acceptance is another factor that can cause splicing performance issues. This is caused with a differential delay between the modes‚ which can cause a lower bandwidth. Lastly‚ you have chromatic dispersion which is the limited bandwidth of certain single mode optical fibers. This affects due to the length of the

ASSIGNMENT 4 WEEK 1 - STORAGE DEVICES Describe the main working features of ONE of the following storage devices. Hard disk drive Optical storage Flash memory Include any relevant diagrams that help explain your answer. Optical Storage The optical storage device that most of us are familiar with is the compact disc (CD). A CD can store huge amounts of digital information (783 MB) on a very small surface that is incredibly inexpensive to manufacture. The design that makes this possible is

predates optical fiber and has its roots in wartime efforts to develop secure communication systems that did not require cable and could withstand radio jamming. FSO has been around for more than a decade‚ but it is only recently that interest in this technology has started to grow. Free Space Optics (FSO) communications‚ also called Free Space Photonics (FSP) or Optical Wireless‚ refers to the transmission of modulated visible or infrared (IR) beams through the atmosphere to obtain optical communications

OCCUPATIONAL LENSES What is an Occupational Lens? An Occupational Lens (or Enhanced Reader) is a reading lens that has a Degression zone to incorporate the Intermediate prescription (and sometimes‚ depending on prescription‚ a good DV portion) Why dispense an Occupational Lens‚ instead of a Reading pair of glasses? With more and more people using Computers‚ Laptops and Smartphones‚ we demand more from the Intermediate zone than ever before. So by dispensing a pair of Reading glasses to a

The horizons of optical networks are much more than high speed physical layer transport. An intelligent optical network design must include higher network layer considerations. This is the only book currently on the market that addresses optical networks from the physical layer to the network layer and should be valuable for those who try to understand the intricacies of what optical networks can be. —Vincent Chan‚ Professor‚ MIT Department of Electrical Engineering and Computer Science This book
