Unit 4 Assignment 1 Copper vs. Fiber Pape
The two most common and widely used cabling types today for the means of communication all over the world are copper and fiber. They both do the same thing, transmit information from point A to point B but both have their strengths and weaknesses and therefore, a person installing cabling may be reluctant to choose one over the other.
Copper cabling is less expensive to install. Copper wiring is flexible when installing so incase a technician has to bend it around a wall or at a certain angle to reach it to an end point, the cable can handle it. Also equipment to support copper wiring is relatively inexpensive to run. The weaknesses to copper ...view middle of the document...
Unit 4. Exercise 1: Cabling Definition
1. Horizontal Cable-A type of inside cable designed for horizontal use in non-plenum areas.
2. Backbone cable-A cable connection between telecommunication or wiring closet, floor distribution terminals, entrance facilities, and equipment rooms either within or between buildings.
3. Patch cords-Short, manufactured cables offered in various length and colors for patching from permanent cable installations to workstations or switch points.
4. Connectors-The thing copper wires go into that allows them to connect to jacks.
5. Conduit- Is a tube or trough for protection electric wiring.
6. Racks-A fixture for mounting various hardware components providing ease of access, better ventilation, and more flexibility than cases.
7. Punch-Down Blocks- Connection bits which cut the insulation of copper wires and forces the copper itself into contact with a circuit.
8. Consolidation Points- A convergence point for the horizontal cabling of section or floor.
9. Crimpers-used to connect connectors to the connection end of wires.
10. Fish tape- Is a tool used by electricians to route new wiring through walls and electrical conduit.
11. Continuity Tester- Is an item of electrical test equipment used to determine if an electrical path can be established between two points that is if an electrical circuit can be made.
12. Category 5e/6 cable-Is a standardized cable for gigabit Ethernet and other network physical layers that is backwards compatible with the cat 5/5e and cat 3 cable standards.
13. Binder Groups-A Group of wire pairs bound together, usually by some sort of color-coded plastic tape or thread.
14. Hybrid/composite cable- is a telecommunications industry term for a broadband network that combines optical fiber and coaxial cable.
15. Pulling cable-A phrase used to describe the act of running network cable from one location to another.
16. Wavelengths of light- The distance between two successive wave crests or troughs.
17. EMI-Is the disruption of operation of an electronic device when it is in the vicinity of an electromagnetic field.
18. Optical-fiber strand- A thin glass strand designed for light transmission.
19. Index of refraction-Is the speed of light in vacuum divided by the speed of light in the medium.
20. Cable jacket- Is a protective outer covering for a cable.
21. Cladding size- A metal coating bonded onto another metal under high pressure and temperature.
22. Multifiber cable- Is a fiber-optic cable having two or more fibers, each of which is capable of serving as an independent optical transmission channel.
23. Differential Mode Delay- Is difference in the time delays amongst the fiber’s propagating modes caused by imperfections of fiber refractive index profile.
24. Chromatic Dispersion-In fiber optic transmissions, is a term used to describe the spreading of a light pulse as it...
