Figure 2-17. WDM Remote Module
Each WDM module consists of either one (remote module) or two (host module) bi-directional
wavelength division multiplexers mounted within a powder-paint coated sheet metal enclosure.
An SC-type optical connector port is provided for connecting the forward/reverse path optical
fiber to the WDM module. A pair of pigtail leads with SC-type connectors are provided for
connecting the WDM module to the forward and reverse path optical ports on the HU or STM.
7.3 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 indoor mounting shelf
and the outdoor cabinets provide a mounting slot for installing a CWDM Remote Module.
The CWDM Remote Module is shown in Figure 2-18. The CWDM Host Module and Host
Module Mounting Shelf are shown in Figure 2-19. For complete information about the CWDM
system, refer to the Digivance System Coarse Wavelength Division Multiplexer User Manual
(ADCP-75-142).
