8 WAVELENGTH DIVISION MULTIPLEXER SYSTEM (ACCESSORY)
The Wavelength Division Multiplexer (WDM) system is an accessory product that is used when
it is desirable or necessary to combine the forward and reverse path optical signals from one
Digivance system onto a single optical fiber. Each WDM system consists of a host module, host
module mounting shelf, and remote module. The WDM host module mounting shelf can
support two WDM host modules. The RU indoor mounting shelf provides a mounting slot for
installing a WDM remote module.
Each WDM module consists of either one (remote module) or two (host module) bi-directional
wavelength division multiplexers mounted within a power-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.
The WDM host module and host module mounting shelf are shown in Figure 2-13. The WDM
remote module is shown in Figure 2-14.
