May be,  but does not sound to be very logic to select OCXOs for low noise 
and then  stick the 'low noise' label to the bad parts...

Hi Arnold
 
Many thanks for the photos, which confirmed what I understood from your  
previous comments, that the label doesn't say "low noise", it says "phase  
noise".
 
Whilst my comment was meant to be somewhat tongue in cheek, and I agree  
it's very unlikely they'd use noisier parts in the T'bolt and then  advertise 
the fact, that label as it stands still reminds me more of a  fault label 
than one indicating an attribute.
 
If you were given a box of these oscillators, some with and some  without 
that label, could you be sure, without further information or  testing, which 
ones might have lower phase noise?
 
regards
