6.2.3.2 Single-Channel Unit Optical Loss

Table 6-5provides optical loss information for the SCU. See Figure 6-2and Figure 6-3to locate the paths where loss occurs in the SCU (for example, from I to H in a Collector Filter Module [CFM]). Figure 6-2shows an unprotected path, and Figure 6-3shows a protected path in the SCU.
