9. Complete all remaining coaxial connections as specified in the system design plan.
4.7 WDM Mounting Procedure (Accessory)
A bi-directional wavelength division multiplexer (WDM) module is available as an accessory
item for the Digivance system. If the application does not require the use of a WDM system,
skip this section and proceed to Section 4.8. The WDM mounts in a slot that is provided at the
rear side of the HU.
Use the following procedure to install the WDM:
1. Remove the cover plate from the WDM mounting slot located on the rear side of the HU
as shown in Figure 13.
2. Slide the WDM into the mounting slot.
3. Push inward on the two Push/Pull fasteners to secure the WDM to the HU.
4. Carefully coil up the two WDM pigtails to protect them from damage prior to connection
to the HU optical ports.

4.8 Optical Connections
The optical interface between the HU and the RU is supported by either two (non-diversity) or
three (diversity) optical ports. Each optical port consists of an SC optical adapter which is
mounted on the HU front panel. The PORT 1 port provides the optical connection for the
forward path (downlink) signal. The PORT 2 port provide the optical connection for the reverse
