Figure 9-7 Amplified OADM Node Configuration Example
Figure 9-8 shows an example of the channel flow on the amplified OADM node. Since the 
32-wavelength plan is based on eight bands (each band contains four channels), optical adding and 
dropping can be performed at the band level and/or at the channel level (meaning individual channels 
can be dropped).
