Converting house to all fiber

[jc480]

Okay been thinking about converting my house to fiber but man oh man I am coming up short on google for info.

My setup
-1 coax line coming from Comcast that feeds me internet. Terminates to a cable modem
-1 coax line connected to digital antenna with signal booster & powered splitter feeding 5 TVs
-1 Cat5 ethernet run from router to home theater (for bufferless streaming)
-An HDMI in-wall cable system from receiver to wall outlet, inside wall outlet to another wall outlet 20 feet away, wall outlet to TV

I'm envisioning having Comcast run fiber to my house (the junction box outside isn't far) and I guess I want to think about replacing all my coax, at least, with fiber. On the digital antenna I get some signal degradation due to having a line run of 30-50 feet even with the booster.

The antenna and cable have to be on seperate runs due to signal interference issues. If I have fiber can I run both comcast fiber & digital antenna to the same fiber and branch off that anywhere in the house? Assuming both digital antenna signal and comcast internet signal can co exist on fiber.

The unknowns for me are at the termination points...will I need to buy special eternet wall terminals that convert fiber to a cat 5 plug?

Hope this is sort of clear and definitely looking for any resources or experiences of people who've done something like this thanks!
