How to Make Straight Through Cable and Crossover Cable (Step-by-Step Networking Tutorial)

Main ideas / concepts

The video teaches how to make two types of Ethernet cables:

• Straight-through cable
• Crossover cable

It also explains their common use cases in networking:

• Straight-through: connects different device types
• Crossover: connects similar device types

Materials needed

• UTP cable
• RJ45 connectors
• Crimping tool
• Wire stripper

Methodology / step-by-step instructions

A) How to make a straight-through cable

1. Strip the cable jacket on both ends.

2. Arrange the wires using the same color standard on both ends (the video uses T568B):

   • White/Orange
   • Orange
   • White/Green
   • Blue
   • White/Blue
   • Green
   • White/Brown
   • Brown

3. Straighten the wires and insert them into the RJ45 connector.

4. Crimp the RJ45 connector to secure it.
5. Repeat the same process on the other end.

B) How to test

• After creating the straight-through cable, the video states to test if it is working.

C) How to make a crossover cable

1. Strip both ends of the cable.

2. On one side, use T568A ordering:

   • White/Green
   • Green
   • White/Orange
   • Blue
   • White/Blue
   • Orange
   • White/Brown
   • Brown

3. Insert the wires into RJ45 connectors and crimp both ends on this side.

4. On the other side, use T568B ordering:

   • White/Orange
   • Orange
   • White/Green
   • Blue
   • White/Blue
   • Green
   • White/Brown
   • Brown

5. The video emphasizes that in a crossover cable, the two ends have different wire color arrangements (T568A vs T568B).

6. Test if the crossover cable works.

Key takeaway: difference between the two cable types

• Straight-through cable: used to connect different devices, e.g. PC → switch
• Crossover cable: used to connect similar devices, e.g. PC → PC
