Cable Building(3.1.9) and Testing (4.2.9)

• As specified in the 568 standards, your cable may
  have a maximum length of 3m.
• Cut a length of cable.
• Strip off the jacket.
• Separate out the 4 pairs of wires.
• Untwist the wires.
• Organize the wires according to the proper colour
  code and flatten the wires.
• Maintain the colour order and flatness of the
  wires, then clip their length so that a maximum
  of 1.2 cm of untwisted wire is present.

Cable Building and Testing

• Insert ordered wires into RJ-45 plug make sure
  jackets are inserted into plug.
• Push the wires in firmly enough to make sure the
  conductors are all visible when you look at the
  plug from the end.
• Inspect the colour code and jacket location to be
  sure they are correct.
• Insert the plug firmly into the crimp tool and
  crimp down completely.
• Inspect both ends visually and mechanically.
• Use a cable tester to verify the quality of the
  cable.
