7.2 Optical Connections With WDM System

Use the following procedure to connect the optical fibers when a WDM module is installed with

the HU:

1. Obtain a patch cord that is of sufficient length to reach from the WDM host module to the

fiber distribution panel.

2. Remove the dust cap from the optical port on the WDM module and from the patch cord

connector that will be connected to the WDM module.

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

4. Insert the connector into 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 connector 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 PORT 1 and PORT 2 optical ports on the HU and from the

WDM pigtails that will be connected to the HU.

11. Clean each pigtail connector (follow connector supplier’s recommendations) and then

insert the connector into the appropriate optical port on the HU as shown in Figure 3-8.

Note: To protect the optical receiver(s), insert a 10 dB attenuator in the optical path. After

the optical power has been measured, the attenuator may be resized or removed.
