...Elite Core website. I'm going to call them this week but not today.
Just talked to Elite Core about their 4 in 1 cable, and they do not test their terminations to confirm that the completed cable is performing at CAT6 (or any other speed), so that is distressing.
There is also no longitudinal spacer between the pairs in each wire to isolate the pairs capacitatively (if that's a word). Since AES50 is in all my mixers and has shown itself to be sensitive to disruption from certain types of handling, that is important to me since the spacer might reduce that problem, although it also seems like the problem would be reduced if the cable is bulky enough to not move pairs individually when significantly jostled.
It sounded like the four internal cables were not isolated much from each other, only by the foil and by some cloth or something. The spaghetti on each end has to have jacket added, he did tell me that part. (The Gepco UTP seems to have a molded jacket around each internal cable.)
They are sending a data sheet with a cross section of the cable to confirm, but I am suspicious that this is not a product for AES50 users, despite the rep's repeated assertion that these cables are "used by the largest production houses in America and they have no problems with it."
This is disappointing, because I am hoping to get another 250' snake and a 4-in-1 cable would be better than the 3 twisted individuals I'm now using on that cable, for a couple of reasons.
Also FYI: I started by doing the Chat on the website, and mistakenly sent only the word "Hi" by hitting the return key.
While still typing a follow up that was more complete and suggesting that it would be simpler to talk instead of type and including my phone number, the phone rang and it was "X from Elite Core! How are you doing?"
!!
I asked how this was possible before I sent the Chat note; he said they can see as you type.
So that was interesting, too.
No email yet in the time it took me to type this, but I'll report when it comes.
Man, I wish Gepco made an STP version of their Quad cable! (I did ask the Elite Core guy if Gepco OEM'd their cable, and he vigorously said no, and that he would be fired if he told me who did. I said I didn't need to know.)
FWIW Belden owns Gepco now, and it's not cheap to build a custom cable factory, so the former Belden guy, Steve Lampen, who was one of the presenters at my Ethernet cable workshop a few years ago, talked often about how they made cable for people all over the world to the customer's specs, no matter what they wanted. Including directional cable in which the signal flowed better one way than the other. The guys in the warehouse were happy to put an arrow on it to indicate the correct direction.
It seems like a non-zero chance that if this cable isn't being made in China it's being made to order by Belden.
Fake edit: Had to leave before posting this, so in the meantime the data sheet came (attached below) and they're also going to send a 2' chunk to see its construction. The drawing seems to show a jacket around each internal cable. Hmmm. Dissecting the sample will confirm this or not.
Elite Core seems pretty responsive and is trying to be helpful; hope it works out that I can buy something from them. That kind of responsiveness deserves support.
