We had a break in one of our fiber cables last year and had a branch of the
local phone company come out and take a look at it.  They hooked up something
called an Optical Time Delay Reflectometer and it gave us a very good idea of
where in the breach the cable was.  Our search was kind of confounded by
having a lot of excess cable still on the spool on one side of the link, but
by hooking up the OTDR on both sides of the cable and doing a little estimation
based on building drawings we found the break a lot sooner than we thought.
Before they came, we were ready to pull the cable out and replace it.
