Apologies if this isn't the right place for this question.
I'm converting an out-building to a home office. The structure is approximately 175 feet from the house. We're digging a trench for a 240V power line, and I'm planning to include a network cable so I can get a fast connection back to the rack in the house.
Is CAT-5e suitable for this? Typically, one wouldn't run a signal cable next to a power cable. Over 175 feet, I imagine that the interference / crosstalk would be significant.
I'm also considering running single-mode fiber. The cable prices are reasonable, and there's no real opportunity for (significant) interference from the power line.
Suggestions? I assume this is a solved problem, but my Google kung-fu is failing me.
I've seen gadgets that will let you send network traffic over the power lines, but have no personal experience re:reliability or performance.
I'm coming up short on tags for this post.
