If you use fiber, be sure to run it through a conduit, just to prevent an errant 
shovel from ruining your day in the future.  Also, be sure you bury a wire or 
some sort of metal with the fiber so that you can find it again in a few years. 
  I buried a fiber cable some years ago, and it was such a short run we thought 
there was no need for a tracer.  Then the local power company decided they 
wanted to change some of their runs, a side effect being they wanted to go right 
across where the fiber line was and they needed to know where to not dig. 
Fortunately, we had used a plastic conduit for the fiber, mostly to avoid the 
afore mentioned errant shovel, and were able to push a copper ground wire 
through the conduit to help us locate it then and in the future.
