1.4.2 Single Y-Cable Protection Module

Table 1-4 details the single-mode and multimode front panel Protection B mapping. It shows how two

DWDM receive inputs (client working and protect) provide one output signal to the equipment, using

the module combiner function.

Table 1-5 details the single-mode and multimode front panel Protection B mapping. It shows how the

module splits a single receive input from the equipment into two DWDM output signals (working and

protect) to the client.
