Making Cat5 / Ethernet Cables using Crimp Connectors

    I was doing this and wasn't really paying attention to the cutting of the cable. Each of the 8 wires of this cable were actually stranded, instead of a solid wire.

    Anyway, I got them in order, and shoved them in and crimped it.

    Then I just happened to look at the end of the connector and noticed that the copper wires from one seemed to be touching another.

    Checked it with a VOM, and sure enough they were shorted at the end.

    Now this would have been FUN to diagnose if I hadn't noticed it.......

    SO, when you cut those little wires, use scissors or something and make sure they are all nice and square with no copper sticking out before you shove them into the connector.........z

    Cat 5 cable is braided that just the way its made, and yes you should not have any wire showing other then right at the tip of the wire. Now as far as cable touching, depending on what color it was, it might not have even mattered.

    It would have mattered with my POE setup........lol......besides......touching wires is a BIG no no.......lol...............z


    And I was talking about the individual wires, which consisted of 7 very thin copper wires..........z

    Stranded CAT5 is a total pita to put ends on. Note, for a good connection you also need proper ends for stranded vs solid wire.

    If your having problems working with stranded wire, you can always tin the ends with a little solder and a soldering iron.

    most crimp on connectors do not need to have the wires stripped, the brass contacts go thru the jacket, I use a razor blade to finish cut the stranded wire. this make a very clean end for use in the crimp connector.

    at work I have come across some patch cables that have stranded wire. Luckily the only time I ever chopped into one of those patch cables, I was punching it down onto a keystone, so it wasn't extreme hell. It threw me off by a bit ;)

    Cheap CAT5 Cable

    TIP for those intending to do any serious CAT5 wiring.

    There are 8 wires in CAT5 cable, normally only one set of 4 is used. Some applications require all 8. Many manufacturers of cables are cutting costs (and cheating customers) by using substandard wire in the second set of 4. The cable resistance is about 3 times higher than the first set of 4. It makes it useless for POE or long cable runs.

    All Chinese manufactured cable I have ever tested has been of poor quality, including AMP cable.

    For most people, this doesn't matter. But keep it in mind, and test your cable resistance if in doubt.

    IDC connectors for braided CAT5e

    Normally available crimp-on (IDC) connectors for CAT5 are intended only for solid cored cable. They will not make reliable connections to stranded cored flexible cable (intended for patch connections).

    In my part of the world, nobody has ever seen connectors for stranded cable - they aren't commonly available. Nor is the cable - it's only usually seen in commercially made patch cables.
