Can this be used for 3 independent Ethernet connections (so using 12 pairs)?

Looking to run 30m of 3x Ethernet in a single armoured cable if I can’t do it as 3 separate cables.

My alternative is to use conduit, but this brings other issues.
 
I'm fairly sure the amount of crosstalk may be an issue with the 25pr cable, as it was generally just designed for analog phone / ADSL connections.

You'd likely be better with some of the cable that is essentially just a bundle of normal cat5e / cat5, like the below, but I haven't found any that is armoured.

Is it 25 individual Cat5e pairs, or are they arranged as six bundles of four with the proper twist in, plus one random additional pair? If they are individual pairs then as above, I think it will only really be suitable for voice.

It’s individual twisted pairs, it’s definitely used for Ethernet as I’ve found diagrams showing it used for backbone connections between switches. But can I find anything that describes what the actual signalling is, not a jot. The colour coding is per 5pairs so it’s not even 4pairs.

Considering getting one of those multi-Ethernet cables made up with armour as a solution.

Use fiber to ethernet media converters.

TPLink MC220L, they are bomb proof. We use about 15 of them in work, never had one break or drop a connection. They take any SFP you can throw at them (1gb or 100m only)

I can’t put anything else into the box due to ATEX regs, so stuck with copper.
 
I've done my fair share of data cabling, never heard of the stuff you've found, so wouldn't want to vouch for it working etc
