Reply to comment by VanillianArt in can you run an ethernet cable through an empty conduit in your house on your own? by VanillianArt

In general, I don't run pre-terminated Ethernet. I find it far far easier to pull it and then terminate it myself. You can find spools of it on Amazon, and then you'd need to buy the proper tools to terminate (about $100-150 investment including a bigger spool). You can try buying a premade cable and pulling it with a fish tape and line, but depending on the size of the conduit you may get stuck.

Do make sure that you don't make your cable TOO long, especially if you care about fast links (10Gbps, though 1Gbps and 100Mbps can be affected too).

It's pretty tough to make an ethernet run TOO long in a normal residential application. Even Cat5e max recommendation is 100 meters with about 5ns propagation loss per meter. Even in a very large home, 30m or so is about as long as you would typically see.

Yeah you probably need some sort of yard and connecting buildings for that to matter.

The max for 10Gbps is probably shorter.

Its actually the same 100m recommendation, just with Cat6a.

Although when you are talking "too long" here you mean WAY too long. Like an extra unnecessary 40 feet. Having an extra 4 feet is no issue.

A good quality cable can carry 1Gbps over some 80-100 meters. Splice it and you reduce the maximum significantly (as low as 20 meters before it slows down and maybe 40-50 meters before it fails completely)

I didn't even realize you could splice cat6

In my house everything is twisted pair (up to the GPON). I've seen some splicing done because we wouldn't redo the wiring, and it was fine (15 meters or so, 100Mbps). Now I have proper unspliced Gigabit links.

You can splice basically any cable. The splice WILL negatively affect the signal so it's a game of whether you can afford that

Agreed, though I will say to date I've never had 1GbE impacted significantly by length and I've surpassed the max many times. Definitely depends on the existing environment.

If you prevent external interference in some other way you can break the rule I guess.
