> Like you can't model 1 cat5 split into two 100mb terminations Ugh I don't really blame them there, that's really a dirty hack. Sure I've done in a pinch but not for permanent stuff. I wouldn't call that professional network management. If you really wanna do it, just split the pairs over two patch ports IMO.

One of the achievements in my career I’m lowkey proudest of is sneaking in the rewire of about 45,000 ports on a campus that were split pair after an explicit project to do so was shot down.

Of course, but a splitter in a PON network or a WDM device are perhaps better examples of things that are hacky to model. Multi-fibre cables and splices are another. Netbox is great for some simple applications, and it's fantastic OSS, but in practice falls short for many use cases.

  I understand, my cabling OCD got a bit triggered, sorry :)

> Ugh I don't really blame them there, that's really a dirty hack. I certainly wouldn't do it today, but using two pair for a connection designed for two pair isn't a dirty hack, it's as designed. Today, using 4 pair for 1G or more and a small switch on the host side to get more ports is probably a better plan.

  Oh I wasn't aware of this actually being an intended usecase. And yes like the other poster said, pairing it with a phone infrastructure was more common (in the days before these went all IP of course). It was a bit of my OCD being triggered as well. I love neat cabling at work (at home it is chaos funnily enough).

Yeh it's awful, but all of our CCTV was wired like this through patch panels with 24v/48v power injectors. 2 cameras a cable. So that's what I needed to document, because in reality I can't book scaffolding and change rooftop cameras for a documentation tool.
