Received a 15216-MD-40-ODD, but all the channels are even
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?

Thank you for the link, this confirms that the mux's label is in fact showing odd channels.
Yes we are using a 15454-10E-L1-C with tunable laser set to 1556.15, which I have confirmed with an optical spectrum analyzer. (Previously, we set the laser to the frequency set on the mux's label, which resulted in about 10 more db loss and we measured that loss on two adjacent mux channels.)
Now that we know this is an even mux, we can use it, but thanks again and I will report this to Cisco TAC so they are aware of the problem.
