If this channel's centerline and bandwidth match a channel
specified in the ITU grid DWDM standard, the name of that ITU
channel will be shown here. The naming convention for 100GHz
channels will be the two digit ITU channel number. For 50GHz
channels, the convention will be to specify either the C or H
band, followed by the two digit ITU channel number.
For user-defined channels that don't match an ITU channel, this
object will report 'N/A'.
