Faced with those kind of problems with poles, can't they dig?

  That's not any simpler. You still need all kinds of clearances to run cables underground, and it's a lot more work tearing up streets.

    And digging is much more expensive to do initially (think two or three orders of magnitude), though it's often cheaper in the long run due to less maintenance and repairs.

      The problem with digging is that in case of faults, it's far more difficult to service. Also, future upgrades (e.g. fibers with better optical properties, or more fibers) require re-digging.

        You don't redig for more fiber unless you really screwed up the initial dig. Always leave lots of room in the tubes to blow more glass down later.

        When done properly, conduit is laid that fiber is then run through. You don't re-dig to lay new media, you simply drag it through the existing conduit. That's why "dig once" is such a big deal. http://www.muninetworks.org/tags/tags/dig-once http://www.muninetworks.org/tags/tags/dig-once http://www.sfexaminer.com/sanfrancisco/san-francisco-seeks-to-speed-up-fiber-internet-expansion/Content?oid=2908441 http://www.sfexaminer.com/sanfrancisco/san-francisco-seeks-t... http://www.whitehouse.gov/the-press-office/2012/06/14/executive-order-accelerating-broadband-infrastructure-deployment http://www.whitehouse.gov/the-press-office/2012/06/14/execut...
