Curious to know what your speeds were before and after. I don’t think it’s the fiber so much as the speed and upstream network, but glad you are happy!
Fiber is inherently immune to lightning and power issues. If your inside modem takes fiber you are pretty safe but if the modem connects through the exterior wall to the fiber via Ethernet you may want to add an Ethernet isolator to keep your internal infrastructure safe OR if you have internal runs longer than 20’. Put those at the end. Living on the coast and having lots of delicate equipment connected I'm a little paranoid.
I tried AppleTV. It LOOKS gorgeous. Just couldn’t find that much I wanted to watch. What are your shows there?
