Shielded, Solid core Cat 5e (Cable maker vs. online post)
« on: September 02, 2014, 05:46:15 pm »

I'm confused.

I've been trying to track down a F/UTP (foil outer shield) Cat 5e solid core for my SiExpression, but I've been running into variations of this a lot:

Good Afternoon Steven,

I have spoken with my Technician and he advises me that most networking
cable should be stranded.
I believe all our pre-wired cables are stranded and not solid.

Note: this is a 150' cable being discussed

However, then I read this, from Mac Kerr:

The standard spec of 100m (328') for Ethernet based runs is with solid conductors. Stranded conductors are often called "patch cables" because they are intended for shorter runs.

Does digital audio travel differently from other network data? Why is it so hard to find long, shielded, solid-core cable? Where do you guys get yours?

ProCo.  http://www.sweetwater.com/store/detail/EtherShld200 there are other vendors including Markertek, TMB, Neutrik, and a couple more in the EU.

The difference between stranded and solid is seen is the capacitance of the wire, which will act as a low-pass filter as the capacitance increases.  The higher the capacitance the shorter the run can be and still meet bandwidth spec.

Network cables are SOLID conductor; Mac rightly points out the typical use of stranded twisted pair.  I've not seen shielded, stranded TP but it's probably because I'm not looking for it...

Yes.

Thank you.

I've always figured the capacitance acting as a low-pass filter was just an analog audio issue. I expected to find mostly solid-core cable in my search, but was surprised to find a lot of stranded instead. I also wasn't expecting a difference between digital audio and network data requirements, which meant I eliminated a bunch of potential sources from my search list.
