7.1.4 Channel Allocation Plans
The following add drop cards utilize the L band DWDM channels:
• 32WSS-L
• 32DMX-L
Table 7-7 lists the L band channel IDs and wavelengths at ITU-T 50-GHz intervals. This is a
comprehensive L band channel table that encompasses future card capability as well as present
capabilities.
