(continued) To achieve full equipment diversity 4-fiber systems would use two optical lines,
one for service and one for protection (Figure 2-3).

Basic WaveStar
OLS 40G Shelf The basic WaveStar OLS 40G shelf holds one or two optical lines identified as
Line 1 and Line 2. If only one line is needed, then either line can be equipped first
(i.e., line 2 can be used before line 1). Refer to Figure 2-4 and Figure 2-5.
