CONNECT FIBER OPTIC INPUT CABLES
Summary: This procedure describes how to connect the fiber-optic cables between the inputs on
the receiver and their termination points on the fiber distribution frame. The connectors on the
cable and the bulkhead connectors must be cleaned prior to making cable connections.
Danger: To avoid exposure to invisible laser radiation, do not look into the ends of any
optical fiber or bulkhead connector. Use an optical power meter to identify active fibers.
Do not assume laser power is turned off or that the fiber is disconnected at the other end.
Danger: Infrared radiation is invisible and can seriously damage the retina of the eye. To
avoid potentially dangerous amounts of radiation exposure, a protective cap or hood
must be immediately placed over any radiating bulkhead receptacle or optical fiber
connector. This practice also prevents dirt particles from entering the connector.
1. Route the fiber-optic patch cords or cables from the distribution frame to the receiver in
accordance with site plans and routing instructions.
2. Clean the fiber-optic cable connectors. Reference DLP-507.
3. Connect the fiber-optic cables to the designated ports at the back of the receiver as
shown in Figure 506-1.
4. Connect the other end of the cables to the designated points on the distribution frame.
5. If all four optical ports are not used, the IPD/SD alarm LED for unused channels will
light when the receiver is turned up. This has no effect on operation of the receiver
however it may be desirable to disable the alarm on unused channels. Refer to DLP-511
for procedures to disable this alarm.
6. Dress all cables, removing all sharp bends.
Stop! You have completed this procedure.
