Three UTP CAT6 in same tight conduit - will that cause interference issues?

[Filingo]

I know in datacenters they stack them by the dozens, but they are probably shielded?

I am using 3 CAT6 UTP cables in same small diameter conduit - can that cause interferences?

 

Ty!

No.

 

Worst case scenario there's a packet retransmit. This is likely to be exceedingly rare. Might matter for 10Gbase-T but... ehh

If I had to pull out some crazy corner case out of my rear, you might need to worry about it in 20 years if you're trying to push 25Gbps or 40 Gbps over it. Who knows if 25GBase-T will even become a thing over CAT 6 (looks like it's CAT8 only right now).

They'll be fine. UTP is designed to be run in bundles.

 

Just don't run them in parallel with line voltage electrical cable. That's where you'll get bad interference issues.

The whole point of twisted pair cables is to be "interference tolerant", the only time it's an issue is when the level of interference is beyond what the demuxer at each end can handle electrically, and you are not going to be in that realm outside of switching high inductive loads on power cables.

thanks everyone!
