7.12.4 40-WXC-C Channel Plan
Additionally, the 40-WXC-C has two virtual diodes. Virtual diodes are monitor points for each physical
photodiode; they are identified with a physical diode relative to the way that the physical diode is
identified with one of the two interlink (ILK) ports. Table 7-38 lists the virtual diodes.
7.12.4 40-WXC-C Channel Plan
Table 7-39 shows the 40 ITU-T 100-GHz-spaced, C band channels (wavelengths) that are cross
connected by the 40-WXC-C card.
