7.8.4 40-DMX-CE Card Power Monitoring
For the ROADM functionality of other cards, see the description of that card in this chapter. For a
diagram of a typical ROADM configuration, see the “9.1.4 ROADM Node” section on page 9-12.
7.8.4 40-DMX-CE Card Power Monitoring
Physical photodiodes P1 through P40 monitor the power at the outputs of the 40-DMX-CE card. P41
monitors the total multiplexed power at the input, calibrated to the COM-RX port. Table 7-23 shows the
returned power level values calibrated to each port.
7.8.5 40-DMX-CE Card Channel Plan
Table 7-24 shows the 40 ITU-T 100-GHz-spaced, C band channels (wavelengths) that are demultiplexed
by the 40-DMX-CE card.
