7.7.4 40-DMX-C Power Monitoring
For other cards’ ROADM functionality, see that card’s description in this chapter. For a diagram of a
typical ROADM configuration, see the “9.1.4 ROADM Node” section on page 9-12.
7.7.4 40-DMX-C Power Monitoring
Physical photodiodes P1 through P40 monitor the power at the outputs of the 40-DMX-C card. P41
monitors the total multiplexed power at the input, calibrated to the COM-RX port. Table 7-20 shows the
returned power level values calibrated to each port.
7.7.5 40-DMX-C Channel Plan
Table 7-21 shows the 40 ITU-T 100-GHz-spaced, C band channels (wavelengths) that are demultiplexed
by the 40-DMX-C card.
