Figure 3-10. Fiber Optic Connections To WDM Module

3. Clean the patch cord connector (follow connector supplier’s recommendations).

4. Insert the connector into one of the WDM module’s optical ports (port 1 or 4).

5. Route the patch cord from the WDM module to the fiber distribution panel.

6. Identify the OSP 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 optical fiber termination.

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

Figure 3-9 and as diagramed in Figure 3-10.

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.
