How to Terminate with an RJ45 Connector

 

If you'll be installing or maintaining a Local Area Network (LAN), one of the most important things for you to know is how to terminate Cat5, Cat5e or Cat6 network cables with RJ45 connectors. Rely on our step-by-step guide to take you through your project.

 

PROJECT CHECKLIST

Experience Level: Advanced

Time Required: 5-10 minutes

Steps: 9

Supplies: EZ RJ45 connectors (2 per cable), Modular Crimping/Cable Cutting tool, UTP cable stripping tool

Budget Estimate: $40 (excluding cables)

 

STEP 1

 

trim cable with crimp toolUsing a Crimping Tool, trim the end of the cable you're terminating, to ensure that the ends of the conducting wires are even.

STEP 2

 

stripping cable jacketBeing careful not to damage the inner conducting wires, strip off approximately 1 inch of the cable's jacket, using a modular crimping tool or a UTP cable stripper.

STEP 3

 

separating the twisted pair and individual wiresSeparate the 4 twisted wire pairs from each other, and then unwind each pair, so that you end up with 8 individual wires. Flatten the wires out as much as possible, since they'll need to be very straight for proper insertion into the connector.

STEP 4

 

the individual wires flattened and orderedHolding the cable with the wire ends facing away from you. Moving from left to right, arrange the wires in a flat, side-by-side ribbon formation, placing them in the following order: white/orange, solid orange, white/green, solid blue, white/blue, solid green, white/brown, solid brown.

STEP 5

 

threading the wires through a RJ-45 connectorHolding the RJ45 connector so that its pins are facing away from you and the plug-clip side is facing down, carefully insert the flattened, arranged wires into the connector, pushing through until the wire ends emerge from the pins. For strength of connection, also push as much of the cable jacket as possible into the connector.

STEP 6

 

checking the order of the wires through the connectorCheck to make sure that the wire ends coming out of the connector's pin side are in the correct order; if not, remove them from the connector, rearrange into proper formation, and re-insert. Remember, once the connector is crimped onto the cable, it's permanent. If you realize that a mistake has been made in wire order after termination, you'll have to cut the connector off and start all over again!

STEP 7

 

crimping the connectorInsert the prepared connector/cable assembly into the RJ45 slot in your crimping tool. Firmly squeeze the crimper's handles together until you can't go any further. Release the handles and repeat this step to ensure a proper crimp.

STEP 8

 

trim the excess wiresIf your crimper doesn't automatically trim the wire ends upon termination, carefully cut wire ends to make them as flush with the connector's surface as possible. The closer the wire ends are trimmed, the better your final plug-in connection will be.

STEP 9

 

terminated RJ-45 connectorAfter the first termination is complete, repeat process on the opposite end of your cable

        Many kinds of mod tips (RJ-45) can also utilize a strain relief, a little piece of plastic that is crimped onto the wire directly behind/underneath the rear (cable-side) of the tip. Look at a commercial, machine-made patch cord for an example.

        Strain reliefs may not be necessary in static, immovable, install-once cables, but if you are making a custom-length patch cord, it can't hurt.

          Comments about How to Terminate with an RJ45 Connector:

          Most RJ45 connectors have wire stops, you don't have to cut the wire ends. I rarely see the color wires shown in the photo, normally they're faded or some variation. Correct information though- passed reflectometer test using Fluke Networks Microscanner 2

            This was a good refresher. I had not Terminated a jack in several years.

            Thanks!

              The instructions are adaptable and I shall use them with the crimper that I bought.
