Installation Instructions
The Fiberlink® 7820 Series of fiber optic transmission systems are ready for
immediate use and do not require any special tools or equipment. However, an Optical
Power Meter, such as the Fiberlink® 6615, can be useful in determining optical loss budgets
during your systems design and maintenance.
The following instructions describe the typical installation procedure:
1) Connect the video source to the video input (BNC or S-Video) on the transmitter unit.
2) (Optional) Connect your audio source to the audio input on the transmitter unit.
3) Connect the video output cable to the video output (BNC or S-Video) connector on the
receiver unit.
4) (Optional) Connect audio ouput cable to the audio ouput on the receiver unit.
6) Connect the fiber optic cable to the transmitter and receiver units.
7) Configure your video preferences as described in the Video & Audio Configuration
section of this manual.
8) Configure your audio preferences as described in the Video & Audio Configuration
section of this manual.
9) Connect the Universal Power Supply to the transmitter and receiver units.
For box versions using DC power, please refer to figure 1.
10) When power is applied, the green POWER LED should illuminate, indicating the
presence of operating power. The Video and the Audio LEDs will give an indication
as described in the Indicator LED’s and Alarm Circuitry section of this manual.
Note: The Fiberlink 7820 does not cross convert. For example, if you input S-Video on the
transmitter, only S-Video will be available on the receiver.
Note: The Rack Card version has an additional red LED for indicating the presence of an alarm
condition (loss of signal). Refer to Indicator LED’s and Alarm Circuitry sections of this manual.
Installation Instructions
The transmitting element in the Fiberlink® 7820 transmitter
unit contains a solid state Laser Diode located in the optical
connector. This device emits invisible infrared electromagnetic
radiation which can be harmful to human eyes. The radiation
from this optical connector, if viewed at close range with no
fiber optic cable connected to the optical connector, may be
sufficient intensity to cause instantaneous damage to the
retina of the eye. Direct viewing of this radiation should be
avoided at all times!
