To follow up, all of this fiber is mm and all light is sx to sfp.  Currently all 1gbit, but it will be repulled as 10gbit capable soon... I guess I'm going to have to be a little less cheap and shoot for something under $1000.  I had an off list suggestion of the below listed fluke.  Any other suggestions or reccomendations?

The pen light to confirm that it's the right strand is going to require a little bit more insight to determine if there is an issue with fiber in conduit or patch.

The keyword is Optical Power Meter. There are some all-in-one meters and some simpler meters, it depends on exactly what sort of fiber you're testing and so forth.

The more advanced tool is an Optical Time-Domain Reflectometer, which can tell you where the splices, breaks, and their locations are, but they are considerably more expensive and that's not what you're looking for from the sound of it.
