Installation Instructions
The FiberLink 3620A Series of ber 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 connector 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 connector on the
receiver unit.
4) (Optional) Connect audio ouput cable to the audio ouput on the receiver unit.
6) Connect the ber optic cable to the transmitter and receiver units.
7) Connect the Universal Power Supply to the transmitter and receiver units.
For box versions using DC power, please refer to gure 1.
8) Congure your audio preferences as described in the Audio Conguration
section of this manual.
9) 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.
10) The system should now be operational.
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 3620A 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 ber optic cable connected to the optical
connector, may be sucient intensity to cause
instantaneous damage to the retina of the eye. Direct
viewing of this radiation should be avoided at all times!
