6.2.3 Optical Loss
This section describes the optical loss for the 15252 Multichannel Unit (MCU) and the 15201
Single-Channel Unit (SCU).
6.2.3.1 Multichannel Unit Optical Loss
Table 6-4 provides optical loss information for the Multichannel Unit (MCU). See Figure 6-1 to locate
the paths where loss occurs in the MCU (for example, from B to U in a Network Adaptation Module
[NAM]).
