Making Your Own Ethernet Extenders
Mr. Shoemaker, the electrician
This may not work for everyone. If you waste an ethernet cord or
cause any sort of problem by doing this, I'm not liable, and I'm
not buying you a new whatever-you-broke.
Hey guys, I was recently job-shadowing an electrician, and with his
retaining information, some research, and a tiny bit of brainpower,
I've realized how to make Cat5 Ethernet network cable extensions.
I figure it's a good bit of knowledge to know, and with a quick search
of the site, didn't see anything like it, so I guess I'll share to you.
Bear with me however, that I am no electrician, and don't work much
with hardware, so it won't be too in-depth or necessarily have the
perfect terminology. Also, it should work, but I don't know if it
will work for everyone.
Before making your Ethernet extension, you will need a few basic
supplies, outlined below.
1. A cat5 Ethernet cord
2. Some scissors, or wire cutters.
3. A cat5-compliant modulator
FINDING "A OR B"
You could do this after a few more steps, but I prefer to do it before
I start so I can attach everything quickly without having to stop and
look at this. Basically, what you want to do is locate a port in your
wall where you can plug Ethernet in. After finding one, unscrew the
screw(s) holding it to the wall and use the screwdriver to carefully
pry the current modulator from the plate you just unscrewed. Set the
plate aside and look at the modulator that should be free. Some of
them are different than others, but you should see two rows the sides
Code: Select all
_______________________ | A O OW B BW | A/B - 'A'/'B' row | B G GW B BW | O/OW - Orange/Orange-White |_______________________| B/BW - Brown/Brown-White _______________________ | A G GW L LW | A/B - 'A'/'B' row | B L LW O OW | G/GW - Green/Green-White |_______________________| L/LW - Blue/Blue-White
Once you see this, what you want to do is take off the small plastic blocks
that hold the wires in the modulator in place. Be careful and not break
them, because you'll need to put them back on in a second. When you get
them off, look at what color cords are going into the modulator and
determine if they are using the A or B rows of the modulator. Remember which
it was, and pop the plastic boxes back into place. Now pop the modulator
back into place in the plastic wallplate and head back to your supplies.
MAKING THE EXTENDER
Take your scissors and chop off one end of the Cat5 Ethernet cord. It
doesn't matter which end, since they're the same. Now take your wire
strippers and strip the (usually blue) plastic wire coat down about an
inch, exposing the raw wiring underneath. Seperate all the wires from
each other. There should be 4 pairs of 2, totalling 8 different wires.
Now open the new modulator you bought. It should have come with the
modulator and 2 plastic boxes to keep the wires in place. Now, just
place each colored wire in it's correct position according to A or B
(what you found out earlier) and snip the ends off so they aren't hanging
out. Place the boxes over the cords, as tight as you can get. Wrap
whatever raw wires you have showing in electrical tape, and take a
look at your work.
