Figure 1-3: Application Example 1
In both applications, the combined optical wavelengths are transported to the hub, where
they are demultiplexed and fed into multiple nodes. In Figure 1-3, the return path signal is
carried on a separate fiber (not shown) from the forward path signal. In Figure 1-4, the return
signal is carried on the same fiber as the forward path signal.
