Inserting attenuation is a good trick for the tool box.  It is also used to 
measure error rates on fiber links.

With a reasonable fiber setup, the error rate is so low that it is hard to 
measure.  At low error rates, there is a simple relation between signal/noise 
and error rate.  So insert enough attenuation until you can easily measure the 
error rate, then compute what it would be without the attenuation.
