3.3 Coarse Wavelength Division Multiplexer System
The Coarse Wavelength Division Multiplexer (CWDM) system is an accessory product that is
used when it is desirable or necessary to combine the forward and reserve path optical signals
from up to four Digivance systems onto a single optical fiber. Each CWDM system consists of a
Host Module, Host Module mounting shelf, and Remote Module. The CWDM Host Module
mounting shelf can support up to three CWDM Host Modules. The RU single-STM mounting
shelf and the outdoor cabinets provide a mounting slot for installing a CWDM Remote Module.
The CWDM Host Module and Host Module Mounting Shelf are shown in Figure 6. The
CWDM Remote Module is shown in Figure 7. For complete information about the CWDM
system, refer to the Digivance System Coarse Wavelength Division Multiplexer User Manual
(ADCP-75-142).
