Figure 14. Fiber Optic Connections To WDM Module
3. Clean the patch cord connector (follow patch cord supplier’s recommendations).
4. Insert the connector into the WDM module optical WDM port (port 4).
5. Route the patch cord from the WDM to the fiber distribution panel or storage 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. Obtain two patch cords that are of sufficient length to reach from the WDM module to the HU.
11. Designate one of the patch cords as the forward path link and the other as the reverse
path link and attach an identification label or tag next to the connector.
12. Remove the dust caps from the HU SeRF SFP optical ports and from the patch cord
connectors that will be connected to the SeRF SFP optical ports.
13. 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 13
and as diagramed in Figure 14.
Note: To protect the optical receivers, insert a 15 dB attenuator in each optical path. When
the system is turned-up and tested, the attenuator may be resized or removed.
