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