We have just installed and provisioned a 15454 platform with the 15216 40 channel odd mux demux. Interestingly, setting the laser to 1556.15 corresponds to the 1556.5 channel on the mux. All of the channels on the mux appear to be even and off-by-one.
We have two units with this issue: ADM1350007E and ADM1352001K. Are we doing something wrong?
