5.0 Network+ Certification Cram Notes : Network Troubleshooting

5.2 Explain how to troubleshoot common cable connectivity issues using appropriate tools:

Explain the Common tools

1. Cable crimper: A cable crimper is a tool used to crimp or attach a connector to the end of a cable. The crimper tool applies pressure to the connector to make a secure connection between the cable and the connector.

2. Punchdown tool: A punchdown tool is used to connect wires to a terminal block or patch panel. The tool is used to terminate the wires by punching them into the designated slots or holes.

3. Tone generator: A tone generator is a tool used for tracing or locating cables. The tone generator produces an audible tone on a cable, which can then be detected by a tone probe to help identify the location of the cable.

4. Loopback adapter: A loopback adapter is a device that connects the output of a device back to its input, effectively creating a loop. It is used to test the functionality of network interfaces and to diagnose problems.

5. Optical time-domain reflectometer (OTDR): An optical time-domain reflectometer is a testing tool used to measure the quality and length of optical fiber cables. The OTDR sends a light pulse down the fiber and measures the reflections to determine the length, attenuation, and other parameters of the fiber.

6. Multimeter: A multimeter is an electronic testing device that can measure multiple electrical properties such as voltage, current, and resistance. Multimeters are commonly used in network troubleshooting to test cables and electrical components.

7. Cable tester: A cable tester is a device that tests the connectivity and quality of a cable. Cable testers can test the cable for correct wiring, correct pinouts, and continuity.

8. Wire map: A wire map is a diagram that shows the physical layout of a cable and its connections. Wire maps are used to help diagnose and resolve problems with cable connections.

9. Tap: A tap is a device that is used to monitor network traffic. Taps are inserted into a network cable and allow the user to monitor the data passing through the cable without disrupting the flow of data.

10. Fusion splicers: Fusion splicers are tools used to join two optical fibers together to form a continuous length of fiber. Fusion splicing is used to repair broken fibers or to extend the length of a fiber.

11. Spectrum analyzers: Spectrum analyzers are tools used to analyze the frequency spectrum of a signal. They can be used to diagnose and resolve problems with wireless networks, such as interference from other devices.

12. Snips/cutters: Snips or cutters are cutting tools used to cut cables. They are used in network installations to cut cables to the appropriate length.

13. Cable stripper: A cable stripper is a tool used to remove the outer jacket of a cable to expose the individual wires inside. Cable strippers are commonly used in network installations to prepare cables for termination.

14. Fiber light meter: A fiber light meter is a device used to measure the light transmission of optical fibers. Fiber light meters are used to determine the quality and continuity of optical fibers in a network.
