Comment on If you can't buy it, make it: EN25 corner that fits HDMI cables.
Fondots@lemmy.world 4 weeks agoI’m no electrician, I don’t run a lot of cable, I’m just a maybe-slightly-more-competent-than-average DIY homeowner type
Personally though, I like having cables run through conduits when possible for the ease of running them. I’m not particularly worried about water or mice or anything, it’s just a lot easier to just drop a cable down a pipe or suck a string through them with a plastic bag and shop vac than to try to fish them through the walls, especially anything I might want to upgrade at some point down the line when a new standard comes out like Ethernet or HDMI.

Makes sense. I just meant standard conduit, Ethernet cable straight through the conduit. Not into the home network.
I’ve pulled connectors through odd gaps, I know how it is.

Data rates and cost:
2x Display connections = 40 gbs
2x USB 3.0 = 10 gbs
=> 50 gbs through a CAT 7 is difficult
OM4 fibre optic is dirt cheap (under $1/m) but the KVMs are expensive at $800.
Using optical thunderbolt cables is also very expensive with $700 for the cable and dock.

Again, I just mean literally running Ethernet cables into standard conduits, terminating them, and sticking a HDMI over Ethernet box on either side. In order not to modify the conduits. I don’t know what the bandwidth is for that kind of solution. I’m not presenting it as the only and best option.
Your solution is cool. My own conduits are surrounded on four sides by concrete, so pulling connectors through is something that I only have to do very very rarely. And more often than not I find myself having to change one thing to wireless or use something that can make use of multiplexing just so I can free up a bit of space in there to do something else.
My own network is still an absolutely atrocious 200kB/s DSL through decaying, water-damaged copper lines. And those aren’t going through conduits, those have had concrete poured right over them. Over the 2x1mm thick flat two-strand “cable” that was obsolete when the building was built decades ago. RJ11. Plastic sheath that disintegrates into asbestos or some shit when exposed to sunlight. I’m not describing an ideal data transmission environment here.

$300 per connection: 2 display connections and two USB connections would cost $1200.

Does this answer your question?
My solution isn’t cheap either: 10m USB-C 10gbit: 50€ each(b-stock/customer returns, normally expect to pay 100€), 15m DisplayPort & HDMI: 40€ each.
Total is approx. $200-2500 between cables and building materials.
Wireless HDMI is pretty interesting but low quality and high latency. The 60 GHz never took off and wouldn’t work anyway as it can’t pass through walls.
Wireless USB was a thing with USB 2.0 but it is dead. There was also some 60GHz USB for VR but that also failed in the market.
