Tools, Parts, Materials, Test Equipment


    [010] RJ45 Connector, Male


    [014] Cutter, Wire 4 In. Diagonal
    [011] Strippers Wire 1187
    [012] Crimper, Paladin 8000 Series

a. Gather all required tools and materials.
b. Clear a workspace.
Note: This is for a standard cable not a crossover cable. A crossover cable is terminated on one end to the T568B standard and the opposite end is T568A.

Step 2: Prep the Cable

Prep the cable
a. Remove the outer jacket using a specialized stripper or carefully with a sharp blade. (blue, yellow, red etc)
  1. Cut the jacket back about one inch.
  2. Remove cut jacket
  3. Place boot on wire (not required)
b. Organize the wires
  1. Untwist the wires (only as far back to the jacket if you go further you could reduce quality).
  2. Arrange according to the T568B standard.
  3. Cut the wires about a half inch in length from the jacket (you can place the connector next to the wires to get a better idea where to cut).

Step 3: Terminate the Cable

Terminate the cable

c. Place male connector on cable
  1. With the male connector tab facing down place the connector on the cable.
  2. Ensure the connector is seated properly.
  3. Ensure the wires are arranged properly and haven't shifted during installation.
d. Crimp the male connector
  1. With cable in the connector place the connector into the crimper.
  2. verify the jacket hasn't moved.
  3. Crimp the connector on the jacket.
  4. Place boot over the connector.

Step 4: Test the Cable

Test the cable

a. Test using a continuity tester if desired (or plug one end to a router and the other to a computer for a simple function test).

    @knife141 - Orange on left, tab down. Ill edit and make it clearer. Thanks for the Q.

    Thanks for posting this. One question: when I look at the arrangement of the wires, is this view from the tabbed side of the connector or the smooth side?

    @mh76dk - I don't understand what you mean by this? I am just trying to pass my knowledge forward. I have used tons of tutorials before but none that explained everything in one place.

    If only you could do it without all the spammy shameless selfpromotion
