OADM Modules and Channel Bands
Each OADM module supports a range of channels called a band. A band contains 4 channels.
Table 1-9 lists the OADM modules that support each channel band. All cards are available with or
without OSC support. For correspondence between channel numbers and wavelengths on the ITU grid,
refer to the Cisco ONS 15530 Hardware Installation Guide. See Table 1-8 for more information on the
