It's expensive to put dB meters on every optical interface, and since these
are cheap commodity based switches those capabilities most likely do not
exist.  That most likely explains the reason you did not see any output in
the 9.2 release, which they finally decided to remove altogether from future
versions.  As Richard mentioned, you'll have DOM for 10GE interfaces, but
not the GE.  You get what you pay for... ;)
