On page 107 the book explains that standards exist for the NIC and the cabling so that all networks and equipment would match up if not then you might buy a computer and it not fit your cabling on your network or vice versa. These standards exist so that all equipment would match up and networks could be simplified.
Shielded copper cable is currently best known for POE equipment. Security ...view middle of the document...
This super expensive cabling is used for these types of applications because the shielding help to prevent the Electro Magnetic Interference to be more specific on a security system this shielding and braiding eliminates the false alarms that would occur if not for the shielding.
Multimeter : The purpose of a multimeter is to measure how much voltage or electrical signal that is currently being transmitted thru a cable or medium. A basic tool for any electrician or IT personnel
Tone Generator: This equipment generates audio pulses to components. In the case of audio equipment testing, frequency response and sound evaluation are recorded.
Pair Scanner: A Pair Scanner is used to find faults on cabling in a network.
Time domain reflector (TDR): Used to locate faults in metallic cables (for example, twisted pair wire or coaxial cable). It can also be used to locate discontinuities in a connector, printed circuit board, or any other electrical path.
Lab 4.2 Review
If no minimum bend radius is specified, one is usually safe in assuming a minimum long-term low-stress radius not less than 15 times the cable diameter. It is important to follow this rule because if you over bend this sensitive cable it will not work and you will have to re run the line.
