3. Clean the patch cord connector (follow patch cord supplier’s recommendations).
4. Insert the connector into one of the WDM module’s optical port (port 1).
5. Route the patch cord from the WDM to the fiber distribution panel.
6. Identify the OSP cable optical fiber termination that corresponds to the RU.
7. Remove the dust cap from the OSP cable optical adapter and from the patch cord
connector.
8. Clean the patch cord connector (follow patch cord supplier’s recommendations) and then
mate the connector with the appropriate OSP cable adapter.
9. Store any excess patch cord slack at the fiber distribution panel.
10. Remove the dust caps from the HU optical ports and from the WDM pigtails that will be
connected to the HU.
11. Clean each pigtail connector (follow the procedures provided with the WDM module) and
then insert the connector into the appropriate optical port on the HU as shown in
and as diagramed in
.

12. If the HU supports diversity, follow steps 2–5 in Section 4.8.1 for routing and connecting
the diversity reverse path link.
Note: To protect the optical receivers, insert a 15 dB attenuator in each optical path. After
the optical power has been measured, the attenuator may be resized or removed.
Note: The HU optical adapters are angled to the left. Therefore, pigtails should always be
routed to the HU from the left side of the rack. Routing pigtails to the HU from the right
side of the rack may exceed the bend radius limitations for the optical fiber.
