Step 2 - Damaged Internet Cables: How to Setup & Troubleshoot Computer Networks

"Hi! I’m Mike with expertvillage.com today we’re going to be taking this boring piece of network cable that doesn’t actually work because we had an accident, and we’re going to be putting a new end on it. This is what we’re going to look like when we’re done and I’m going to show you how to get there. First thing you’re going to need is a replacement end, obviously, for this to go in, but it doesn’t just stick in there’s a couple of minutes of work involved. What you’ll need is a cable crimper to be able to crimp all of the individual wires, and there are eight of them, to go into this piece, more on that later. The first thing you need to do is rather carefully cut a good inch to two inch section of the network cable she thing off. So you want to gently cut the pieces off. You can finish pulling it off if necessary. You want to make sure you want to pull the wires out just a little bit and make sure that you didn’t get any nicks on these because they’re very, very, very fine and any nicks can translate into the nonworking cable. It’s pretty frustrating to end up that way so you don’t want it. Okay, now that we’ve got this span out and we’ve checked to make sure that we got no nicks, you’ll see a little cooper sheen there from the light. We want to go ahead and separate these out into the correct pair orders. There’s a specific order that it needs to go into. What you’ll notice is that there are four color pairsl there’s orange, blue, green and brown. There is a solid color and then a white with dot. For example, we got our solid orange and then our white with orange. What we’re going to do these are four pairs they’re often called a twisted pair for obvious reasons they are twisted together as a bundle and these four bundles are twisted together in the cable. What that does is helps reject picking up any noise or line interference or if it’s running next to any electrical currents; it helps reject the noise, sometimes know as RFI or radio frequency interference. What we’re going to do is we have to separate these out into a very specific order, and it’s not quiet this order but we’ll go ahead and pull them out. Our order as we’re going from left to right will start as this. We’re going to a white orange and then our orange what we have to do is move our white brown and brown are going to be our last two so we’ll pull them off to the right hand side. Then we just got two colors in the middle to worry with, which are blue and green. What’s going to happen is that the green moves to the pulled apart."
