2. 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 each connector.

3. Remove the dust caps from the HU optical ports and from the patch cord connectors that

will be connected to the HU.

4. Clean each patch cord connector (follow patch cord supplier’s recommendations).

5. Insert the connector into the appropriate optical port as shown in Figure 3-7.

6. Route the patch cords from the HU to the fiber distribution panel.

7. At the fiber distribution panel, identify the OSP optical fiber terminations that correspond

to the forward and reverse path.

8. Remove the dust caps from the from the patch cord connectors.

9. Clean each patch cord connector (follow patch cord supplier’s recommendations) and then

mate the connector with the appropriate OSP optical fiber termination.

10. Store any excess patch cord slack at the fiber distribution panel.

Note: To protect the optical receivers, insert a 10 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, patch cords should always

be routed to the HU from the left side of the rack. Routing patch cords to the HU from the

right side of the rack may exceed the bend radius limitations for the optical fiber.
