Lab #02: Construction and Testing of Ethernet Straight-Through and


Crossover Cable

Objective:

 To build Category 5/5e UTP Ethernet straight-through and crossover


cables.
 To test cable continuity, pin-out correctness, and proper wire placement.
Summary:

In this lab, we learned how to construct and test two essential types of Ethernet
cables: straight-through and crossover cables, using Category 5/5e
Unshielded Twisted Pair (UTP) wires. Straight-through cables are used for
connecting different types of devices (e.g., PC to switch), while crossover cables
are used for connecting similar devices (e.g., PC to PC or switch to switch).

Straight-Through Cable:

 Both ends of the cable use the same color code (TIA/EIA-568B).
 RJ-45 connectors were attached using a crimping tool.
 Cables were tested for pin-to-pin continuity using a cable tester.

Crossover Cable:

 One end uses TIA/EIA-568B, the other end uses TIA/EIA-568A wiring.
 This configuration allows data transmission between similar devices by
crossing the transmit and receive pairs.
 The cables were again crimped, assembled, and tested for correct
configuration.

Throughout the process, special attention was paid to:

 Maintaining wire pair twists as close as possible to the connector to


reduce noise.
 Ensuring proper alignment of wire colors based on the standard.
 Verifying cable function using a continuity tester.

This hands-on activity helped reinforce practical networking skills and


emphasized the importance of precision and standards in cable construction.
