I've had Spectrum internet service over coax cable for many years, as the only other option was AT&T DSL. A few years back we dropped the Spectrum TV portion and are using YouTube TV. Spectrum was charging $90/month for 500/25 Mbps, which is all the speed we need.
Recently AT&T and T-Mobile/Metrocom each installed fiber in the neighborhood independently. Doesn't make any sense to me why they would both make that investment, but I guess the more competition, the better.
I've got a 1" PVC conduit running from my attached garage to the Spectrum pedestal. It pops through the garage wall at ground level and then the conduit extends vertically into my garage attic. The coax runs across the garage to an interior wall and drops down into my den. A few weeks ago I added a couple of Y's to extend that conduit into the two fiber handhole boxes. While I was doing it the AT&T guy was connecting my neighbor to fiber. I asked him some details about how my installation would work and he was quite perplexed about the conduit. He claimed that they had to put a grey box on the side of my house in order to change from the orange exterior cable to the white interior cable. I envisioned the guy giving me enough fiber cable for me to run it from the handhole box to my den and all they would have to do is terminate it. They apparently need to make it much more complicated than that.
For my neighbor they ran the fiber cable from the handhole box across the lawn to his garage, up the exterior wall, across the front of the garage stapled to the soffit, down the wall to the gray box on the front of the house, and through the wall into the room where the router was to be located. It looked like crap and he made them change it. So now it comes out of the handhole box, across the lawn, laying in the joint in the concrete driveway, across the lawn, laying in the joint in the concrete sidewalk, and then into the gray box. Apparently another lower paid crew comes later to bury the cable. I saw a couple of guys trying to drill a hole under the sidewalk, but they gave up after an hour or so. I was really curious to see how they were going to get under the driveway.
After observing all this, I called Spectrum and after using the fiber availability for leverage, got them to lower my bill to $40/month with a 2 year price lock. And I don't have to do anything, other than the time I wasted with the conduit.
