16.1.8 DWDM Card Channel Allocation Plan
ONS 15454 DWDM multiplexers, demultiplexers, channel OADM, and band OADM cards are designed
for use with specific channels. In most cases, the channels for these cards are either numbered (1 to 32)
or delimited (odd or even). Client interfaces must comply with these channel assignments to be
compatible with the ONS 15454 system.
Table 16-6 lists the channel IDs and wavelengths assigned to the DWDM channels.
3. These values, decreased by patch cord and connector losses, are also the input power values for the OADM cards.
