Study Notes

Cable crimpers are specialized tools used to add connectors to the ends of cables.
Different types of crimpers exist for coaxial, twisted pair, and fiber cables.
For twisted pair cables, crimpers push prongs through the wire insulation to make copper-to-copper connections.
RJ45 connectors are commonly used in ethernet cables and have multiple copper contacts.
Crimping process extends copper connections from the cable into the RJ45 connector.
Good crimps ensure all wires reach the top of the connector and have proper connections to the copper contacts.
When working with cable, also use electrician scissors (cable snips) and a wire stripper.
Wi-Fi analyzers help identify and understand frequencies in use to manage wireless networks effectively.
Tone generators and inductive probes help identify cables in large networks by adding a unique tone to the cable and then detecting it with the probe.
Punch down blocks require specialized tools to connect wires permanently and maintain good organization for efficient management.
Ethernet cables maintain twist throughout the cable, and good documentation is important to keep track of cable connections.
Cable testers perform continuity tests and help identify issues, but more advanced tools like TDRs provide more detailed information for troubleshooting.
Loopback plugs and loopback cables help test interfaces on devices and identify issues with the physical interface.
Physical network taps allow observing network traffic by disconnecting a link and connecting a tap to the network for data analysis.
