9.1.1 Hub Node
Figure 9-2 Hub Node Configuration Example with 40-WSS-C Cards
Figure 9-3 shows the channel flow for a hub node. Up to 32 channels from the client ports are
multiplexed and equalized onto one fiber. Then, multiplexed channels are transmitted to the OPT-BST
amplifier. The OPT-BST output is combined with an output signal from the OSCM card and transmitted
to the other side.
Received signals are divided between the OSCM card and an OPT-PRE card. Dispersion compensation
is applied to the signal received by the OPT-PRE amplifier, and it is then sent to the 32DMX-O card,
which demultiplexes and attenuates the input signal.
