Basic network cat-5-wiring-diagram

A simple cat-5-wiring-diagram can help us avoid a lot of troubleshooting when it comes to home network wiring. It's a good idea to test each rj-45 circuit after you terminate the connection ends.


The testers will test each wire channel in the cable. There will be eight channels and all need to be working. The light will scan through each channel, if the channel doesn't illuminate, you'll need to do over the connections.

To start out, you'll need to first run the cat5 cable. Then to terminate the ends, you'll need to cut or lightly scribe a ring about 1-inch from the end of the cable.

I use a utility knife, then I bend the cable casing so it breaks apart at the cut. There will be a nylon string inside the cable that will get in the way so you need to cut it off.

Now, the cables will be exposed, so put them in order starting with white-orange. See the picture.

OK, so maybe the picture below will show it a little better. Sometimes we have to see it in real life to better understand.

Whoa, the closeup shot looks like a pile of venomous, spitting, cobras!

Sometimes the long wires are unruly, so you need to cut them down to about 1/2-inch. The rj-45 crimper has a special cutter that cuts the wires evenly and straight across.

Push the wires into the rj-45 termination end making sure each wire goes in the order it is supposed to be in.

Next, you can crimp the termination end with the crimper. Squeeze it hard to get a good connection.
