4.1 Wavelength 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
URH system onto a single optical fiber. Each WDM system consists of a host module and a
remote module.
Both the host unit WDM module and the RU WDM module consist of a bi-directional wavelength
division multiplexer. The host unit WDM module is mounted within a powder-paint coated sheet
metal enclosure. A straight LC-type optical connector port is provided for connecting the forward/
reverse path optical fiber to the WDM module. A pair of pigtail leads with LC-type connectors are
provided for connecting the WDM module to the forward and reverse path optical ports on the HU
SeRF card.
The WDM host module mounting shelf and host module are shown in Figure 5. The WDM
module is shown in Figure 6.
