Unpopular opinion: I think fiber splicing beats crimping for most residential jobs now

I know a lot of guys swear by crimping because it's faster and cheaper per connection. But after I tried fusion splicing on a tricky attic run last month in a house near Portland, I ended up with way fewer callbacks for signal loss. The splicer rental was $150 for the day, which stung, but I saved two hours of troubleshooting compared to a similar job where I crimped. What gets me is that crimping seems simpler to learn, but I've seen too many connectors fail after a year or two. On the other hand, I get that splicing equipment is a big upfront cost for a small shop. Has anyone else switched between these and regretted it or found a clear winner?

Fiber splicing in a residential attic? That's like bringing a flamethrower to light a candle. Most houses around here don't need that level of precision unless you're running lines for a data center in the basement. I get that crimping can bite you later, but I've got terminations in my rental from 2019 that still test fine. A bad crimp is user error, not a universal flaw in the method. Maybe your crimper was out of spec or the connectors were cheap.

Right, I've been there. A decent ratcheting crimper and name-brand connectors make all the difference, but even then, you gotta check the little blades are actually seating the pins right before you commit. Saved myself a callback more than once by just looking at the first one under a desk lamp before doing the rest.
