How To Terminate CAT 5 Cable With An RJ-45 Connector

Picture of How To Terminate CAT 5 Cable With An RJ-45 Connector
In this Instructable, i will teach you how to Terminate CAT 5 Cable with an RJ-45 Connector. This is easy when you get the hang of it, and becomes second nature after about 15-20 minutes. After you learn to Terminate CAT 5 Cable, you will be well on the road to Terminate 4 & 6 Wire Telephone Cable, and have a slight idea about Coaxial Terminations. I will be VERY shortly be making an Instructable about Terminating Coaxial cable as well.

This is a great skill to know especially if you decide that you want to persue a networking career sometime in life. For those who have NO intentions on becoming a networking specialist, this is a great skill to have that will save you hundreds to pay someone to come out and do these things for you. You may need to shorten cable, change the location of the cable to a more convenient spot, or you might have moved, and now you are having trouble figuring out where you need to route your cables for your network.

Step 1: Materials Needed

Here is what you will need to complete this project:

CAT 5 Cable (Length is custom to your project but its smart to have a few samples ready for practice)
RJ-45 Connectors
Connector/Cable Boots (they make matching color boots for your color of CAT 5)
RJ-45 Crimping tool (found @ lowes or home depot)


A word on your tools:
The crimper i have is a combo tool made by IDEAL that included a RJ-45 die, and a 6 wire Tele. Cable Connector die. it also included connectors for both types of cable and costed me about $50.00 give or take. this will be the most expensive part of your project, but in the long run worth every penny.

I have a 15 year old business card with the diagrams that's becoming quite handy the older I get. What is a crossover cable & what does it accomplish?

Thanks,
Zapp

A crossover cable is an ethernet cable that has two of the four pairs of wires inside it crossed over into each other's respective spot on one end of the cable. in NORMAL x-over cables, its the 1st and 3rd pairs that get crossed over. SEE PICTURES BELOW. IE:

ETHERNET END: 

  1   2    3   4   5    6    7      8
WO O WG B WB G WBR BR


X-Over End:

  1    2   3   4    5   6     7     8
WG G WO B WB O WBR BR

The pictures below show what the cable terminations should look like.
Picture 1 is the crossover end, and picture 2 is the normal end.

The X-over cable's purpose is to like two like devices together to share a network connection (such as two laptops, two desktops, a desktop-laptop, etc.), and to link switches together.

Now this explanation is the simplified version. it does not include the Gigabit crossover cables, and "high performance" type x-over cables where MORE than 2 pairs are crossed over. usually a standard x-over cable can support gigabit connections, it just wont have the performance of gigabit.

Was really hesitant to put it there, but thanks. Remember back when I started doing ends. I was so confused, but now one could almost do it blind folded. Now you can show them how to do a crossover cable.

Whenever i figure out what the issue is, i will takt this comment down...until then it is staying up. Thank you for your patience with this matter and thank you again for reading my instructable!!! i hope it helps you!!
Gosh I have made so many of those and crossover cables also.

Thanks for the comment and better diagram of the termination!!! I actually had to take my camera and snap a picture of my phone's screen to get the diagram i included from my ElecDroid App (so handy to have haha).
