6.8.1 Optical Connections Without WDM System
Use the following procedure to connect the optical fibers when there is no WDM installed with the
HU:
1. Obtain two patch cords that are of sufficient length to reach from the HU to the fiber
distribution panel.
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 the connector.
3. 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.
4. Clean each patch cord connector following the patch cord supplier’s recommendations.
5. Insert each patch cord connector into the appropriate optical port as shown in Figure 13
and as specified by the following:
PORT 1 FWD - Forward path patch cord
PORT 1 REV - Reverse path patch cord
6. Route the patch cords from the HU to the fiber distribution panel.
7. At the fiber distribution panel, identify the OSP cable optical fiber terminations that
correspond to the forward and reverse paths.
8. Remove the dust caps from the OSP cable optical fiber adapters and 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 cable adapter.
Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation
can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not
look directly into the optical transmitter of any unit or exposure to laser radiation may result.
An optical power meter should be used to verify active fibers. A protective cap or hood MUST
be immediately placed over any radiating transmitter or optical fiber connector to avoid the
potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles
from entering the connector.
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.
Caution:
Improper handling can damage fiber optic cables. Do not bend fiber optic cable more
sharply than the minimum recommended bend radius specified by the cable manufacturer. Do not
apply more pulling force to the cable than specified.
Note: The HU optical adapters are angled to the left. Therefore, always route patch cords
to the HU from the left side of the rack. Routing patch cords to the HU from the right may
exceed the bend radius limitations for the optical fiber.
