RJ45 Connections - Some Basic Hints

  1. The RJ45 connector is the critical connection - always use the highest quality connectors you can afford. The most common cause of connection faults are bad connectors.

    There are different connectors for stranded and solid cable and manufacturers do not always do a good job at differentiating them. Spend the time to make sure you have the right connector type. If you use the wrong type of connector the cable may or may not work initially but it will almost certainly fail very quickly.

  2. Make and test practice cables until you get it right every time - especially before you destroy a cable you just spend 2 hours fitting.
  3. When cutting the exterior cover of the cable be very careful not to cut the insulation cover of the conductors since this can cause shorts - bottom line: the cable won't work.
  4. Expose a maximum of 1 inch of individual conductors when preparing the cable for connection.
  5. Line up all the conductors according to the wiring standard you are using.
  6. Measure the cable and trim the conductor ends so they are are all the same length and no individual conductor wire is visible outside the plastic cover of the RJ45 connector.
  7. Carefully slide the prepared cable into the RJ45 connector making sure the end of the conductors reaches the end of the RJ45 connector.
  8. Using the crimp tool make the connection using one firm squeeze operation.
  9. Test the cable before fitting if possible.
