And you dig smaller trenches with them. Microtrenching digs a foot deep and two inch wide hole for direct bury fiber cable, saving time and money over older techniques.

Only a foot deep? My sprinkler system is deeper than that.

ATT recently did fiber by my house with some kind of machine. It did some kind of U shaped trench, where it drilled down (not sure how deep), then over about 200 feet, and back up. So you only see a hole every 200 or so feet, vs a solid trench. Let them go under driveways and all of that.

A team of 4 guys was able to do my entire neighborhood in a day. Still waiting for ATT to actually wire up the fiber, until them I am stuck with comcast cable (which is fine ,except the data cap doesn't scale with speed, so the faster connections cap cap you out in like 15 minutes).
