Making Ethernet cables

Old No Comments on Making Ethernet cables 45

Can you make an Ethernet cable ? Most of you reading this are going to laugh at the question and say of course you know how to make an Ethernet cable. But in all seriousness, you’re the minority.

As you know, my company provides 3rd party IT support services to clients. I see many clients and many locations, and therefore, I see a lot of wiring jobs. And let me tell you, most of the wiring jobs I see aren’t done correctly. Here’s an example of one client’s BRAND NEW wiring:



They had an IP desktop phone connected to this jack and it kept dropping calls and going offline. I fixed this wiring (and got it to less than ½” of untwisting of the pairs), and the IP phone never had another issue.

There are some really basic rules regarding Ethernet wiring, whether it be Cat5, Cat5e or Cat6. These rules need to be followed correctly, otherwise you’ll get weird problems (like the IP desktop phone above). The bigger issue with these problems is that they’re not guaranteed to always point to a wiring fault. Most people would have assumed the IP phone was defective, and replaced it, just to have the same problem. For desktops, Murphy’s law has dictated that the most prevalent issue is random printing errors. Again, these can be hard to track down, because wiring isn’t one of the first things we technologists think of. We assume that if the device is showing connectivity to the network, then it’s working as it should be.

Remember, never assume that someone else’s work has been done correctly. Always verify it yourself before making any conclusions.
