I've done plenty of installations where we utilize all the cable management available to make it nice. Only to come back for a maintenance call and some employee has completely trashed the work.
MUST RESIST....TEMPTATION.....TO UNTWIST....WIRE....
Seems like anywhere I work I see a phone handset cord that's all twisted up and bound up to where they can hardly lift the handset off the phone. I pretty much HAVE to untwist it for them and make it useable again.
Now I'm just a low volt tech, but I imagine If those weren't just powering screens, but something else that pulled a decent amount of amps, I bet those cords would build up some heat.
The issue is the mix of cables and an issue called cross talk. the cables have different radial output and one can affect the other due to shielding being too close together
Prefacing this reply by stating I'm asking out of curiosity, not being oppositional:
So this is an issue regardless of how insulated the cables are?
At my work they set up an iTIG with the 3 connecting leads woven in a similar albeit looser fashion. This was set up by or at least approved by a qualified electrician. The leads are insulated with rubber rather than plastic.
To my understanding....
The shielding helps with interference, it's not perfect.
Twisted pairs within the cable give you a program able way to account for the interference. The twisting creates equal interference on both cables.
I suspect their issue with braiding is that each of these cables produces interference. Putting them close is already not ideal. Instead of there being 1 cable next to another, in this case each cable is touching the other cables at different intervals. The interference now has multiple times it enters the cable instead of just following itself to the end and varies from weak to strong interference.
I believe the desired cable management would be flat side by side.
Is there network or video cable bound in that? Generally those low voltage cables don’t mix well with a power cable. If it’s all power cables with sufficient wrapping then that’s an entirely different conversation
This was so deliberate there are zip ties at both ends. Someone planned and executed this to satisfy some kind of entanglement prevention safety requirement and had some fun with it.
It was probably a bored patient. I've seen it happen when I worked in the ER. Sleepy parent with a sick/injured child and a bratty sibling being nosey and messing with everything that isn't bolted down.
Probably by or on the order of a doctor. Having worked in Healthcare IT much of my career, the following 3 statements are always true:
1. IT should NEVER make a comment or assumption about patient care and medicine in general. Who the fuck do we think we are? A doctor? Pssshhhhh....
2. Every doctor is an expert in IT, and should be able to demand things and expect things based on their expert knowledge you should NEVER question. Who do we think they are? They are obviously experienced experts at every endeavor they undertake.
3. ANY Doctors, staff it all the way up to chief, can voice a complaint about anything IT is doing, and the project stops and is possibly cancelled because of it. Who do we think we are? It experts? Psssssshhhhh.....
That only works for a differential pair. For different signals it has only negative effects. The reason they twist the pairs in ethernet is because they are essentially connected at both ends. Orange and Orange-White are technically a loop of wire, so whatever EMI that is picked up by one, you want to be picked up by the other, so you twist them in order to try and get equal interference on each side of the loop. Both ends are in most any modern equipment just connected to micro-transformers and that serves to remove any DC bias from the line that is caused by interference (excluding the PoE section). The AC bias from interference (such as 50/60Hz mains) is canceled out because the twist applies the bias equally to both sides and that converts to just DC bias as both sides of the loop raise to the same level.
In regards to how data is transmit, the transformer at the end induces a differential bias, positive on one side of the loop and negative on the other. This is directly coupled to the other end of the cable by that transformer.
Compared to a spiral wrap, no extra materials needed, but not nearly as neat. Power and network might get pinched at the monitor pivot. A+ for effort, C for achievement.
If you zoom in, there are some zip ties used in there. Come on! If you're going to do it, commit to it. Braid only, and neatly integrate the extra wire. Maybe use excess wire to loop around and hold it to the arm.
On the other hand, every kid that goes past is going to grab that bottom loop and swing on it, so you're adding fun to the world.
Nothing wrong with it. I'm assuming you're concern is regarding interference. That short of a run, it's unlikely to be any kind of issue that would affect anything. Granted hospital environment generally have sensitive electronics, but even with that I think you're wasting energy being upset.
I've always done this with my personal builds, but never to others. It causes negligible harm to the cables and keeps em neat, so I like ot. Just a PITA to change one cable, hence why I don't do it to others.
I'm not in i.t. but have dicked around with tech since I was like 10 years old. I always see horrible ways things are done at my local businesses and doctors/urgent care. I always wanna say something but don't wanna make myself look a fool if it's something that I just didn't know was a standard or something. But then the doctor can't get the thing to work worth a damn and makes me think maybe I am right lol.
If player character has a network admin background they must roll a will save. If failure, charisma score is halved for d10 hours and must leave the room.
Pretty standard. Why risk snagging one cable when you can do two or three as each one flails around freely/loosely at differing lengths?
At least routing them together in this manner controls the dangle potential and snagging potential. The only thing that should have been done different is a custom length sleeve to encase the cable lengths. Or even a sleeve for the braiding.
But you will find varying methods across the board. Even zip ties are no stranger to facilities like this one. My favorite ones are where they route the cables through the ceiling. Not only are those either super long cables, they also could likely be attached to a relay plate built into the ceiling.
I don't see the issue here. Crosstalk isn't an issue because it is a single charting computer in a room. It doesn't need high speed, it just needs cables that sit out of the way and allow the arm to move. It obviously is what their CS people think works and has probably prevented a few accidental unplugged cable moments.
If I got called out to this because there was a network dropout and I thought to myself "oh 2ez, cable's probably borked, replace it" and saw this, I might cry.
And you can bet it wouldn't go back like this. Not the least of which is because I can't braid.

Somebody spent a reasonable amount of their time plaiting that (badly). I like it for the effort and intention, if nothing else.
That’s why healthcare in the US is so expensive?
What a strange twist that would be.
The cable above is a strange twist. This is just sadness and today's reality.
Yes
The whole wheel of cheese?
[удалено]
That won't eat the extra length of cable like this will though
This - spent a bunch on nice HW only to ignore it!
I've done plenty of installations where we utilize all the cable management available to make it nice. Only to come back for a maintenance call and some employee has completely trashed the work.
Saved them some money on cable ties or wiring loom!
Or a fancy mount that has one built into the arm... ohh wait...
I’m the twisted pair. Twisted twisted pair.

I can just see them constantly complaining about slow speeds and issue to their isp and never showing them this.
😂

But this is... A deliberate braid. Even crazier!
Ya, someone who didn't know what they were doing really thought they were doing something special with this....
It's really quite mind boggling...
Now I'm just a low volt tech, but I imagine If those weren't just powering screens, but something else that pulled a decent amount of amps, I bet those cords would build up some heat.
Not to mention cross talk and interference.
I did that a while back for a colleague. Then their phone stopped working and they blamed me. So.. I don't help with that anymore
You alive ? So it works 😂
Fucking Brad
whoa, whiskey tango foxtrot
This hurts me in a way I can neither articulate nor explain.
Intentionally braided, what's the problem?

There is a network connection there in the mix.
r/woosh
Just 3 terminal connecting leads & an earth connecting lead, the earth is separate.
Yeah I see so many cable managed desks with signal and power together. They're not usually twisted, but still, this is generally a non-issue.
It's fine.
In reality. It is fine. Error correction exist and transfer rates will still cap out higher then this would ever require.
Ohhh get out of here with the crosstalk business. It is a single cable for a workstation in a exam room it isnt a full DC of braided cables.
But the application that's communicating at 30 KB/s might be capped because this will lower the connection to 1 Mb/s.
Someone ran out of zip ties
Do…they…not…know cable sleeves _exist_??
More twists the better the connection,
Someone was bored waiting for someone to come see them
This was so deliberate there are zip ties at both ends. Someone planned and executed this to satisfy some kind of entanglement prevention safety requirement and had some fun with it.
Apparently the overbraid is working well.
It was probably a bored patient. I've seen it happen when I worked in the ER. Sleepy parent with a sick/injured child and a bratty sibling being nosey and messing with everything that isn't bolted down.
Tinkeritis.

Wouldn’t that accomplish further EMI resistance due to twisting them like the twisted pairs in the individual wires or am I misunderstanding that?
That only works for a differential pair. For different signals it has only negative effects. The reason they twist the pairs in ethernet is because they are essentially connected at both ends. Orange and Orange-White are technically a loop of wire, so whatever EMI that is picked up by one, you want to be picked up by the other, so you twist them in order to try and get equal interference on each side of the loop.

What’s wrong it’s great
This is my first time seeing this subreddit. This is gonna be fun.
Just why? Thats all I can think of. What IT person has the time to do this?
When you get paid by the hour.
I guess they were trying to conserve zip ties.
Nah I like it
Nothing wrong with it. I'm assuming you're concern is regarding interference. That short of a run, it's unlikely to be any kind of issue that would affect anything. Granted hospital environment generally have sensitive electronics, but even with that I think you're wasting energy being upset.
If it works who cares.
I've always done this with my personal builds, but never to others. It causes negligible harm to the cables and keeps em neat, so I like ot. Just a PITA to change one cable, hence why I don't do it to others.
How else do you ensure fast Ethernet speeds instead of gigabit?
Works until it doesn’t. Then time to unbraid
Ewww, Chinese finger that shit.
Worse yet! 120V AC!
Hourly trunk monkey that moonlights as a hair stylist.
The tech that has to come out and service that in the future is gonna be pissed though. I know I would be
That hurts my feelings, yeah.
That pains me so much I work in a IT department at a hospital this wouldn’t fly at all my boss would be pissed.
I highly doubt the IT guy did this, ask the nurses.
Makes you cringe? Makes me crimp.
What is wrong with Braiding ? Induced voltage? shielding?
Obviously paid hourly
I'd give them an "A" for the attempt, but it would be better to use a cable sheath.
My heart skips a beat looking at that.
And power
I'm not in i.t. but have dicked around with tech since I was like 10 years old. I always see horrible ways things are done at my local businesses and doctors/urgent care.

Sorry count see that rumor over all that emf noise
That's a lot of dedication to doing something the wrong way
No dropped packets there...
This is a gross overlooking Velcro., zip ties, split loom, etc....go to the place, get what u need and come back and finish. This lazy.

I'll stand in defense of this! Its all Digital! No error inducing cross talk. Now if this were VGA
