Study Notes

Cable Crimping and Tools

Cable crimpers are tools used to add connectors to cables, similar to pliers, but specifically designed for connectors
Different crimpers exist for coaxial, twisted pair, and fiber optic cables
This is a final step, usually performed after running cables
Crimpers for twisted pair cables push prongs through insulation to connect copper wires inside
RJ45 connectors are commonly used with twisted pair cables; they have prongs engaging the wires; the copper connections at the end connect to the device
Crimping creates a solid connection of copper wires to the connector's prongs
Cable crimpers securely fasten the connector to the cable
Good quality cable cutters (electrician's scissors or cable snips) and strippers are also essential
Wire type (Cat 5, Cat 6, Cat 7) affects connector type, use the correct connector for the cable

Wireless Network Troubleshooting

Wireless networks use radio frequencies; a Wi-Fi analyzer is crucial for diagnosing issues
Wi-Fi analyzers are software/hardware devices that identify occupied and available frequencies on a wireless network
Useful for high-density Wi-Fi environments or understanding interference/signal strength
These tools facilitate adjustments of antennas and network configurations

Cable Identification and Testing

Tone generators and inductive probes (toner probes) are used to find cables in large bundles (data centers)
Connect a tone generator to one end of a cable and use the inductive probe to find the cable, its sound indicates its signal
This is effectively used to quickly isolate and find a specific cable.
Cable testers perform continuity checks (if connections are complete)
- Tests if pins 1-8 are properly connected
- Identifies if wires are crossed/missing ensuring correct connections

Punch Down Blocks

Punch-down blocks are used for permanent cable connections, specifically for multiple cables (data center, etc.)
A specialized tool, the punch-down tool, is needed for this operation, cutting and neatly fastening multiple wires to the block
Record-keeping on connections is important when using punch-down blocks
Maintain the twists throughout the cable installation process
Maintain accurate data and records when using these blocks.

Advanced Network Tools

TDR (Time Domain Reflectometer) is a more complex tool for measuring signal loss or cable faults
Loopback plugs send data back to the same interface, used to assess if there is an error with the physical device's interface
Loopback plugs connect a device to itself, helping diagnose device problems.

Network Monitoring

Network taps (passive and active) can capture data traversing a connection.
Physical network taps are used to copy data between devices
Switches also include functions to send data copies to a third-party (port mirror or SPAN)
Use a protocol analyzer or monitor to check traffic between two or multiple devices
Switch port analyzers (SPANS) temporarily copy network data to a separate interface.
