other end? ;-)

  We just completed a Data Center migration and I have a whole box full of 
cables that were pulled from the old location. These are mostly LC-LC cables 
from servers to fiber switches. Nothing over 30 meters. I was just looking for 
a device that would tell me whether or not the cables were still good (no 
breaks, etc.). I certainly don't need anything along the lines of an OTDR.

     I don't really know much about it, but I have been told by a couple
    installers that testing fiber isn't like testing copper.  There's no
    cross-talk or other fancy stuff like the copper testers do.  All they
    do is measure the power loss (in dB).  They do that by using a simple
    meter and a light source.  The measure the source to the meter, then
    they put the run in line, measure that, and take the difference.

     Of course, the installers could have been full of sh*t.  They often are.

     I do know that an OTDR (Optical Time-Domain Reflectometer) is an
    expensive gadget, but all it does is tell you how long the cable is,
    or where the break is, if it's broken.  That's very useful if you're
    looking to find a break to put in a repair splice, but it's useless
    for quality acceptance purposes.
