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 6-4provides optical loss information for the Multichannel Unit (MCU). See Figure 6-1to locate the paths where loss occurs in the MCU (for example, from B to U in a Network Adaptation Module [NAM]).
