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