3.2Wavelength Division Multiplexer System

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 and a remote module. The HU provides a mounting slot for installing a WDM host module. Both the RU outdoor cabinet the RU indoor mounting shelf provide a mounting slot for installing a WDM remote module.

Each WDM module consists of a bi-directional wavelength division multiplexer mounted within a power-paint coated sheet metal enclosure. A straight 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/remote module is shown in Figure 5.
