I run all of my large video distribution via fiber. It's never DIY, and never will be. What others see on the market is what is marketed to them. This will never be fiber, just termination tools are pushing a grand. But its basically zero loss. I agree on the conduit suggestion, but I started using fiber in 1998 when I buried it all over 360 acres and a 3/4 mile driveway for surveillance and communications. There was no reliable option besides that. Even now, it's very viable. You never have surge issues, weather issues with RF, interference issues with RF. You do not worry about emi,rfi issues. There is almost unlimited bandwidth with fiber, it's a very small diameter, can run with romex if needed, I can go on and on. It is being installed to homes in urban areas around here now for on demand tv, and Internet service. Those with it here get better services into the home than those without.
There are lots of CI even whom have no experience with it, and therefore denounce it. But then they are the first ones to recommend using optical audio on HT gear. Lol, i understand it I guess as they have no experience with it. Take a look at the hubs, and what kind of media you can send and receive on just 1multimode fiber, much less 2. Or just take at look at a real Crestron system, and enough said.
Now, I like cat rated cables, and I really like RG-6, as RG-6 is the most underused cable ever. It is good for so much more than it gets, and carries large amounts of bandwidth. But you cannot depend on wireless, copper has faults, limits, and not secure for communication from people who wanna tap or listen in so to speak. But fiber is safe and secure, immune to transmitting surges, and has no value to those pesky wire thieves whom steal and sell copper. LOL
