Wired connections, which use Ethernet cables, are generally faster and have lower latency than Wi-Fi connections. But, just as modern Wi-Fi hardware has advanced, modern Ethernet cables are capable of communicating at faster speeds. RELATED: Upgrade Your Wireless Router to Get Faster Speeds and More Reliable Wi-Fi For a typical home network, this isn’t a really big deal, since your Internet. Feb 22, 2017 How to Crimp Rj45. RJ-45 connectors are normally used in telephone and network cables. Occasionally they are used for serial network connections. When the RJ-45 connectors first came into use, they were primarily used for telephones.
Is there any easy way to straigten the pairs in a cat 6 cable? I've been making network cables lately, and I was wondering if there was a trick other than just a lot of practice for straigtening out the small wires.
Thank you.
EDIT: I ended up buying some $18 snips. They have the indentations on the back of the blade for just this purpose. It works great.
Not really much of a trick, but I tend to get them in the correct order, and then massage them back and forth between my thumb and forefinger. Alternate directions as you do it, switching from pulling towards your thumb and towards your forefinger. With each pull, run your fingers from the sheath to the tips of the pairs, as though you're warming it up like putty. Usually works to make them nice and straight, for me.
I give myself a little extra wire when stripping the outer sheath. After that, I bend them all outward from each other, at a 45-90 degree angle and untwist the pairs. Then I bend them back, get the wires in the right order, and straighten them out just enough to push them into the RJ45 connector. After that, I push them into the connector a couple times to finish straightening them out. Then I trim them to the right length, push them in one last time, and make sure I can see the shiny ends flush with the plastic when I look through the end of the connector, and finally I crimp the connector.
It doesn't take many cables' worth of untwisting to kill your fingertips! In the past, when I've had to unwind about 10' of twisted pair for hobby projects, I stuck the end of the wire in an electric drill and tightened the chuck. Then I just pulled the drill's trigger until the pair was unwound. If you could figure out a good way to quickly clamp and release the pairs, you could do the same with an electric screwdriver to untwist the small amounts of wire needed for putting an end on.
I use what is called a 'spudger' it's an old phone company tool used to pull twisted pairs out of a bundle or what we called a 'rats nest'. It's made of plastic and looks like a pencil with a small 90 degree metal 'hook' on the end. Greybar has them for less than $5 get the one with a pointed end or file the blunt tip with a small file to make a point. You could also go to the hardware store and get set of 'picks' or probes they look like a dentist's tool. Strip the cable, separate the pairs, trim them off to about 2 inches and stick the 'spudger' between the twisted pair and pull. I have done thousands of RJ-45's. After you've done a couple hundred you'll be doing it in your sleep.

I just wrap my pliers jaws on some thin cloth, clamp the wire somewhat hard and then pull it.
Pinch each individual wire between your thumb and a screwdriver. Starting closest to the sheath, using the thumb of the hand holding the screwdriver bend the wire over the screwdriver and start pulling the screwdriver up the wire. It straightens the wire pretty well. If you need to terminate more than a few conenctors you may want to wear a glove to protect your thumb.

I leave the individual conductors a little long, get them positioned in the correct order, then grab them between my thumb and forefinger and bend them back and forth, uh, horizontally. I think the best way to describe the direction is if you had a flat piece of ribbon that you were holding in the same way, I'm talking about bending it the way the ribbon wouldn't want to bend.
Also, it's much easier to straighten solid wires than stranded wires.
I like to divide the 4 groups of wires into the roughly the right spots first, then unwind and place them between two fingers and pull. It helps if the wires are roughly the right length to begin with, as that makes for less untwisting. I've also found that there is some variation between brands, and of course, no matter what method you use, it's going to need some practice.
If you are making a lot of cables, I recommend that you buy your cables prefabricated. (eg. From Monoprice) It's not that expensive and it can save you a ton of time and headache.
My Fluke punch-down tool has a fold out hook that's perfect for separating the pairs like the spudger above. Then I use the ribbon trick.

Use slightly ling wires and take screw driver in the last loop after that pull it up to the end with low force then you will get the stright wire. Eg:- Hair Comb.

Terminating an Ethernet or CAT5e/CAT6 cable is an easy and useful skill, particularly for those interested in home networking or those in the networking field. When you learn to terminate cables yourself, you can save money, space, and frustration with tangled cables by making them the exact length you need instead of having to use cables manufactured by a company. In about 15 minutes, almost anyone can measure and terminate the ends of a cable.
Step 1: Materials
• Wire Strippers – I recommend the IDEAL Telecomm/Datacomm Wire Strippers • Wire Cutters (Side Cutters will work) • RJ45 Crimping Tool • 2 - RJ45 Modular Data Plug (Ends) • Bulk CAT6 Network Cable • Ruler • 2 Wire Boots (Optional, not pictured)
Step 2: Measure the Cable
Step 1: Using the coil of wire, pull the necessary amount of wire for the connection you need to make. Be sure to include an extra 2 inches on either end of the wire for the data plug. NOTE: Network cables have a maximum length, depending on which type is being used. Although maximum length varies by manufacturer, a common rule of thumb is 650 feet for a CAT6 cable and 250 feet for a CAT5e cable. If the length of the wire between two powered network devices exceeds this length, signal degradation and data loss may occur. TIP: Do your best to run the wire along the path it will follow between the two devices. Do not pull the cable tight between two points and be sure the cable is not kinked or tightly pulled around corners. The cable should have a little wiggle room. TIP: If the location of the wire allows, consider including an extra length in the cable. This prevents having to make another cable if one device needs to move a short distance after the cable is made. One way of adding a short length to the cable is to wrap it around a closed fist 2 or 3 times.
Step 3: Strip the Cable
Step 1: Measure out 1.5 inches from one end of the wire and place the wire in the wire strippers at that location. The cable should be snug in the strippers, but not tight. For the recommended strippers, the second notch inward is appropriate. Step 2: Ensure the blade of the wire stripper is perpendicular to the wire and turn the wire stripper around the cable once, which will score the sheathing of the wire. NOTE: Turn the wire stripper only once. Turning the stripper more than once increases the chance of cutting the sheathing of the inner wires. If the inner sheathing is cut, it can make the next steps more difficult or cause the wires to break. Step 3: Remove the wire stripper and gently bend the cable along the score line. This should break the sheathing which can be pulled off the wire and thrown away. NOTE: Some wires contain a strand of fiber similar to the one shown in the image. Cut the fiber from the cable near the end of sheathing. NOTE: As you become more experienced with making Ethernet cables, you may not need to remove the full 1.5 inches of sheathing. After the sheathing is removed, the bundle of 8 wires will be exposed as shown.
Step 4: Prepare Wires
Step 1: Separate the twisted pairs into an 'x' pattern as shown. When you look down the cable from the end, you should not see any of the twisted pairs crossing over each other. Also, the wires do not have to be in the same configuration as seen in the image as long as the wires are not crossing over each other. Step 2: Separate the wires of the twisted pairs. When the wires are separated, they should not cross over each other. Step 3: Assemble the wires into a fan shape and organize for the data plug. There are two common ways to organize the wires for the data plug. Regardless of which one you use, both ends of the cable MUST use the same configuration otherwise the cable will not work. I use the following configuration moving left to right (Clockwise from the 9 o'clock position) • Orange-White • Orange • Green-White • Blue • Blue-White • Green • Brown-White • Brown TIP: If this is the second end of the wire, look at the end that is already terminated to ensure the cables are the same on both ends. If you made a mistake on your first end, this is your opportunity to fix it by configuring your wires the same way as the terminated end. NOTE: The wire configuration used above is the T-568B configuration, which is the most common configuration. The T-568A configuration works just as well and will not affect the transmission quality of the cable. Both of these configurations use the design of the wires (twisted pairs) to insulate the wires from each other and prevent interference and data loss. It is useful to memorize whichever configuration you prefer. If you are interested in making an Ethernet Crossover cable, just do an image search for 'Ethernet Crossover Cable Diagram' to get a wire configuration diagram. Step 4: Firmly grasp all the wires near the sheathing and slide your fingers up, collecting all the wires into a flat line. Make sure none of the wires jump positions. When looking at the wire colors from left to right, the wires should be in the same configuration as described above. Step 5: Straighten the wires. The wires do not have to be even, just straighten them as best you can. TIP: If you have a table with a sharp (not rounded) edge, pinch the cable between your thumb and the edge of the table. Next, pull the wires between your thumb and the edge. This will straighten the wires and make them easier to manipulate for the next steps. Step 6: Using the wire cutters, trim the tips of the wires so all of the wires are even. Make sure the cut is perpendicular to the wires.
Step 5: Insert Wires and Crimp
If you are using boots, place 2 boots on the cable now with the large ends of the boots facing the ends of the cable (The large ends of the boots should be facing opposite directions). I choose not to use boots because as the plastic ages it become hard which can make unplugging a cable from a jack very difficult. Some people counter this by saying it keeps the tabs from breaking off if you have to pull the cable through a bundle of wires or a tight space, but if the tab breaks off, you can cut the end and terminate it again! Step 1: Ensure the wires are still in the same configuration as the last step. Insert the wires in data plug as shown in the figure. The tab on the data plug should be on the bottom of the plug and the Orange-White wire should be the leftmost wire in the plug. When inserted, the sheathing should be just inside the end of the data plug. If the wires are too long, remove the data plug, cut a very small length of wire from the end, and reinsert the cable into the data plug. NOTE: When viewing the data plug from the side, all of the wires should be as far forward in the plug as possible which is past the spikes at the closed end of the plug. Also examine the plug from the end, ensuring all the wires are completely inserted in the plug. TIP: The the wires do not want to slide into the data plug, moisten them with a drop of water or, if you are comfortable, a small lick will do the trick. Step 2: With the sheathing just inside the plug, pinch the wire about 2 inches below the plug. Using your other hand, pinch the wire just above where you have pinched and slowly slide your second hand up towards the plug, like you are stretching the sheathing. This will move the sheathing farther into the plug. Repeat this step until the sheathing is near the center of the plug. Be sure you are not pulling the wires away from the end of the plug. NOTE: If you push the sheathing too far into the data plug, you will start pulling the wires back into the sheathing. Make sure all the wires are fully inserted in the plug. Step 3: Insert the prepared plug in the crimping tool and squeeze the handle, crimping the wires. NOTE: Typically, I actually squeeze the cable in the crimping tool twice. I know it does not do anything extra, but it also cannot hurt.
Step 6: Terminate the Other End of the Cable
Now the other end must be terminated. Return to the 'Strip the Cable' step and repeat the stripping, preparing, and crimping steps for the other end of the cable. Congratulations! You have terminated an Ethernet cable! Now you are ready to interconnect the world!
