Metal Foil AND Braided Shielding

Most shielded STP Cat5e will feature either foil or braided shielding, our pure copper STP Cat5e cable features both aluminimum foil and braided shielding to drastically reduce EMI (Electromagnetic interference) and optimize the signal strength of your network. We also include a thin cellophane wrapper that is common in STP cable to preserve the consistency and shape of the twisted pairs and its shielding.

Pure Copper

PureRun Cat5e cable is made with Pure Copper for the cleanest connection and most reliable quality. If you want your system to perform, get Pure Run cable. This SolidRun cable is rated to the highest specs for Cat5e passing fluke tests at 350MHz (compared to 100Mhz for common CCA cables). Pure Copper better combats interference, packet loss, and other things that might slow down a network.

Easy Pull and no Tangles

With help from our customer's feedback we've managed to perfect the pull-box so that you can grab one end and sprint to the end of your cable run without snags or tangles. We've also beefed up the jacket from past models to ensure its integrity no matter what your install style is.

Solved Interference Problem - 4/5/2013 6:54:36 AM

Pros: Good Price Fast Delivery Pulls Well

Cons: Jacket could be more flexible

Other: We use this in an industrial setting, where regular cat5 has too much interference from 3 phase electricity and motors. We are using this for PLC and remote I/O connections, also for data acquisition and smart card readers. Since we started using this double shielded cable, we have had no issues. Highly recommended for factories and industrial environments.

Pros: Heavy Jacket Good Shielding Good pair twisting

Cons: Heavier than UTP Not as flexible as UTP

Other: Both con's are common sense, and nit-picky. Good product so far!

Great for an STP

Pros: great and flexable! which most STP are not! wires are clearly marked with whites. Does what STP is supposed to do very little interference. I like it cause it's easily ran, took less time to run this cable than the UTP.

Cons: Terminating the ENDS are horrible! trying to cut through the woven shield does not work with traditional methods. You can't actually grab one end and run with it, and the cable pulls easily, the box will just fallow you. gets caught every so often

Other: The weaved wires are definitely worth the trouble.

I am looking at cat 5e cable part #SW-9421, It looks to me like the "shielding" is made from plastic. Is this STP shielding copper or aluminum, foil or braid ?


This cable uses both foil and braided aluminimum metal shielding whereas many other cables use one or the other. In the image you can also see a thin cellophane wrapper that is common in cables to aid in preserving the shape and consistancy of the twisted pairs and its shielding.

Does this product support POE, and is it UV rated?


The SW-9421 does support POE. Unfortunately it is not UV rated but you can run it outside if you use a conduit and have no issues.
