Ewww T568B.
Category 5 is even easier to make than 5E.
Please dont bend and pinch your cables. Make a loop as shown in the bottom middle.
Add a piece of string to tie it.
And no zip ties. Zip ties are for attaching cables to other things, and should never be tightened fully.
Velcro ties ftw.
tie the cable into a knot, it's the fastest and least damaging way to store cables
If we are taking a gentle loop, sure. But if you mean (and I've seen this BTW) tying like a pair of shoes and pulling it tight, I'd kick you out of my IDF.
Not saying thats what you were thinking, just had to share my memory of that pain.
I still prefer a bit of waxed thread though. Great for any cable, be it utp, f/utp, armored, fiber, coax, whatever. But that's also how I started, so it probably plays a role in why I like it.
Edit: plus a string makes a nice and neat way to hang it on a hook.
Ugh this takes me back to my electrician days: trying to splice these fuckers in a dark, hot attic, with only a blue-hued headlamp to help you piece out what color everything actually was. Good times.
I mean they make HDMI over CAT extenders, just get a pair
HD baseT
HDBaseT is cool, except in my experience the transmit/receive units get WAY hotter than I think make any sense. We used then at my last job for AV solutions, both 'high end' Crestron units and cheap Amazon.com randos - they all got HOT to the touch!
If only this had taken off in the consumer market.
Imagine a future where video was just ethernet and we didn't have to worry about crappy cables or DRM
AV over IP is the latest trend in the commercial world actually.
Interesting! Is that usually like HDbaseT or SDVoE? Would you recommend it for menus and screens in a bar?
I could see a lot of uses for a product like this for bars and offices I work in, but I would imagine the could might be prohibitive if it's more than a few hundred dollars per unit.

It's been mostly called AVoIP, I don't know if I'd recommend for menus at a bar, it's more of an easy way to change inputs to multiple displays, before with hdbt tx/rx pairs, you had to have either a switcher that had hdbt inputs/outputs (usually limited ports) or all your tx/rx pairs in the rack feeding into a switcher and a control unit telling the switcher to switch. With the avoip, it's just a control unit and arranger connected to the network switch. It's a little slow but it's still developing.
After reading that I thought the 'HDMI Forum' was a literal internet forum of nerds who invented HDMI and didn't want to make it open source for anyone. lol.
tbh high bandwidth cables over copper are a bit of an anti pattern.
Would be a lot cheaper and compact if ethernet and video over fiber were more popular already
Having professionally terminated fiber, that shit is nasty and hazardous in a way copper will never be.
The little fiber bits can be razor sharp, you have to be careful of the naked fiber end, because it can get into your skin like a splinter, only it is clear, nearly invisible, can shatter if grabbed too hard, and is invisible to MRI and X-RAY scans...
I mean, if it weren't more dangerous, it would be really unbalanced. You want the player to have to make active choices with upsides and downsides.
The equipment required to fuse glass fiber to connectors is still slightly more expensive than a set of crimp tools. Really cool machine though
You don't need to fuse every fiber connection unless you're doing really long distance fiber.
For runs inside a building, single pulls with mechanical splices would work just fine. You shouldn't get much loss as long as there aren't more than two or so mechanical splices.
Source: worked as a technician for a fiber optic ISP.
Oh, I've never heard of mechanical splices, only the ones that heat and melt the fibers together. Can you do custom lengths? Is there a machine that does it?
I would genuinely love any info you have
It's basically just an end you attach to the fiber:

You'll use a cleaver to break the fiber at a 90 degree angle to reduce attenuation, and slide it into the connector. Once it bottoms out, you press something down and it grabs the fiber, holding it in place.
I know it's Youtube, but here's a video of the process:
https://www.youtube.com/watch?v=WuKm7t87SJU
The idea is you would pull a fiber cable through a building and terminate it with ends like these. Then install them into a bulkhead to make them similar to solid-core CAT5/5e/6 cable into a patch panel. You can then use premade jumpers to connect from the building wiring to the devices you're using.
The fusion machines are generally used for long distance links because of the significantly lower attenuation per splice. A fiber line that goes 40 miles is likely to have tens if not hundreds of splices in it depending on the number of spans of cable, and industry standard for fusion splices is 0.00-0.05 db attenuation per fusion splice.
That is super cool! Thanks for taking the time to reply!
That's mostly because too few people use them.
The engineering requirements are also a lot higher. It's the difference between a nut, bolt and spanner, compared to a welding machine.
Yeah, probably wont be possible for people to make their own data cables for much longer. Fiber cables are much cheaper and thinner than copper at least, so not as much of an issue to buy different sizes instead of making them yourself.
Just be careful unspooling it, it loves to kink up and any bend with a radius tighter than like 2 inches ruins the cable.
I once helped my brother run about 15 strands through his house and only around half of them actually worked when we were done. Wish we knew that when we started.
Back-coiling is a game changer. Every other coil is reversed, leaving a net zero in coils. It just pulls out straight.
It was a leftover spool from a contractor friend of his that would have just been thrown away otherwise.
