Hi, I think it tells you in the description what they both are:
"A2D readouts (if they differ), are reported in parentheses." DOM = Digital optical monitoring A2D = Analogue to digital Without thinking too much about it I suppose that the digital signal and analog signal could differ if there is some loss in the quality of the signal (so D2A has more issues recognising a "0" or "1"). Optics isn't really my field so I'm speculating, someone else might have a better answer on that. regards, Tony. >________________________________ > From: nasrul azim <[email protected]> >To: "[email protected]" <[email protected]> >Sent: Saturday, 27 April 2013 9:27 AM >Subject: [c-nsp] cisco show Interface transceiver detail > > >Hi all, i'm a bit confusing to read the fiber transceiver detail. >Which one is the correct one in brackets or outside the bracket.
