Copper Trunk Cables: Measuring Techniques


JT:    Today we’re going to talk about the uses and measuring techniques for our copper trunking products. To best illustrate this we’re going to help our lab engineer Brittany.

Brittany:    Well JT, what I’m trying to do today is test out some VLANs. So, I have to go from this 24-port switch over to the central patching unit and I guess I’m looking for an easy way to do it.

JT:    Well, that’s perfect. Our copper trunks are going work great. I’ve already taken some time to pre-order you some stuff. First, I picked the 24-port modular copper panel; this will go above the switch. For the central patching location I picked the 72-port 2U panel. That will allow for future growth expansion. And here are our pre-measured copper trunks. We chose CAT6 12-leg riser rating; Brittany, why don’t you tell them how we measured these?

Brittany:    Measuring copper trunks is relatively easy. You only need about four simple measurements to be accurate. The first measurement I took was from the switch to the bottom of the cabinet. The second measurement I took was underneath the floor from the switch cabinet over to the central patching location. The third measurement that I had to take was from the floor all the way up to the central patch location.

JT:    But Brittany you said there was four measurements. What about the last one?

Brittany:    That’s right, JT, don’t forget to add 10 percent for bend radius and extra cable management.

JT:    Pulling the cable is easy, no snags because of this braided mess.

Brittany:    Compared to 110 punch downs these pre-terminated copper trunks are a snap to install. Take a look.

JT:    We also have a nice rear cable management bar to tie down the assemblies. So Brittany what do you think?

Brittany:    Well I’m now ready to test my VLANs in no time at all thanks to the installation of copper trunks. It really cut down on my install time.
