In the world of cabling there are two types of cables and they are Copper and Fiber Optics. Some companies chose fiber over copper but those companies have the money to use Fiber Optics and some just go with copper because it is cheaper to use. Each of these two cables has its own strengths and weaknesses. Copper: Conductivity and Heat Resistant Copper wires are second only to silver when it comes to electrical conductivity. Compared with other non-precious metals, copper wires can handle a

Plenum The air-handling space between the walls, under structural floors, and above drop ceilings when used to circulate and otherwise handle air in a building. Plenum-grade cable can be run through these spaces if local building codes permit it. Decibel (dB) A standard unit used to express a relative measurement of signal strength or to express gain or loss in optical or electrical power. A unit of measure of signal strength, usually the relation between a received signal and a standard signal

processing requests and switches and routers will have to analyze and forward data packets at a higher speed to keep up with the evolution of Ethernet. Cat5e, Cat5 and CAT6 are the most recent Ethernet Evolution; they are the standard and most easily affordable for companies to use. The ease of installment is also a big factor when using CAT cables, twisting and lining up the end connectors is all that is required. The biggest issue with using CAT is that in starts to lose signal after 100 meters, it

Renee Montaque 1.2 M2 Why copper is used in electrical cables Mobiles have lots of different metals in them for example, Copper is used for electrical circuits and they are good conductors. Silver is used for switches on a circuit board and phone buttons because it's a really great conductor. Gold is used for the surface of the circuit board and a connector. Tantalum is used in electronic components and it allows scientists to make small mobiles and phones have palladium, aluminium and

Assignment 1: Cable Testers Wire-Map Testers A wire-map tester transmits signals through each wire in a copper twisted-pair cable to determine if it is connected to the correct pin at each end. Wire-map testers detect transposed wires, opens, and shorts which are all problems that can render a cable useless. A wire-map tester consists of a remote unit that you attach to the far end of a connection and the battery-operated, handheld main unit that displays the results. Typically, the tester displays

over to this new system. The company was working on a low budget and did not have enough money to install the CAT 5E cables that are necessary for this type of phone system or so they thought they were necessary. This company had very old wiring system throughout the buildings and would have to spend a lot of money to update the wiring. They started out using the original Cat 3 cable that was already in the building. After six months of converting over to the new phone system with the old wiring they

and removing data cables from the hard drive. The second step is to extract all of the PCI adapters and the video card. Keep in mind that each of the adapters attached to the motherboard are secured by a single screw on the back rail of the case. Place these screws in a container to prevent loss of the screws. Handle the adapters by the metal brackets while removing them. Now it is time to begin removing the data cables. While using both hands to disconnect the data cables, hold it as close
