Chapter 5 Multiplexer and Demultiplexer Cards
5.1.4 Channel Allocation Plan
5.1.4 Channel Allocation Plan
ONS 15454 DWDM multiplexer and demultiplexer cards are designed for use with specific channels in
the C band and L band. In most cases, the channels for these cards are either numbered (for example, 1
to 32 or 1 to 40) or delimited (odd or even). Client interfaces must comply with these channel
assignments to be compatible with the ONS 15454 system.
Table 5-6 lists the channel IDs and wavelengths assigned to the C-band DWDM channels.
Note In some cases, a card uses only one of the bands (C band or L band) and some or all of the channels listed
in a band. Also, some cards use channels on the 100-GHz ITU grid while others use channels on the
50-GHz ITU grid. See the specific card description or Appendix A, “Hardware Specifications” for more
details.
