Welcome | Features | Package Contents
Welcome
The FiberLink 7220 Series is a transmitter/receiver pair that transmits a single channel of
RGBHV video and two audio channels over one single mode or multimode ber. It is
available as a freestanding box unit or as a card version for use in the rackmountable
6000A card cage.
The system’s all digital encoding delivers noise-free transmissions that retain all of their
initial parameters, regardless of ber optic cable attenuation. System operation may be
easily monitored using integral indicator LEDs on each unit that continuously signify the
presence of baseband video and audio signals.
Features
• Supports VGA, SVGA, XGA and WXGA (640 x 480 up to 1366 x 768)
• Supports HDTV resolutions of 480p, 720p and 1080i (RGBHV format only)
• Uses all digital processing with no compression for crystal clear signals and no color
pixel skewing
• Requires no adjustments, equalization or de-skewing during installation
• Transmits signals over one single mode or multimode ber optic core at 1310 nm
• wavelength
• Low audio/video skew, <300 uSec
• Use with FiberLink 8000 and 8100 Series Optical DAs for complex point-to-multipoint
distribution
• RoHS Compliant

Installation Instructions
Installation Instructions
The FiberLink 7220 Series transmission systems ready for immediate use with with no
special conguration or installation. The following instructions describe the typical
installation procedure and the function of the LED indicators.
The following instructions describe the typical installation procedure:
1) Connect the video source to the video input HD-15F connector on the transmitter unit.
2) Connect the video output on the receiver unit to the HD-15F connector.
3) Connect the ber optic cable between the two Pure Digital FiberLink units.
4) Connect the audio input signals to the transmitter stereo jack and the audio output
to the receiver stereo jack.
5) Apply power to both FiberLink units. For box versions using DC power connections,
refer to Figure 1.
6) When power is applied, the green POWER LED will light, indicating the presence of
operating power. The VIDEO LED will give an indication as described on Page 8.
7) The green AUDIO LED will give an indication as stated on Page 8.
8) 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.

The transmitting element in the FiberLink 7220 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!

The rack card version of this product has an additional red indicator LED that lights when
an alarm condition exists. The rack card unit also provides an output to drive a model 6020
Alarm Sensing Module which provides an audible tone and activates a set of contacts for
external signaling purposes.

Operating Pointers
Remember to check attenuation of the ber optic cable. The system will only operate
properly if these specications fall within the range of the system’s loss budget.
Troubleshooting
Multimode ber optic cable contains an optical ber with a light carrying “core” that is
only .0025 inches (62.5 microns) in diameter. Single mode ber optic cable has an even
smaller “core,” only .00032 to .0004 inches (8-10 microns). This is smaller than a human hair!
Therefore, any minute particles of dirt or dust can easily block the ber from accepting or
radiating light. To prevent this from happening, always use the provided dust caps when
ever optical connectors are exposed to air. It is also a good idea to gently clean the tip of an
optical connector with a lint-free cloth moistened with alcohol whenever dust is suspected.
The status of the LEDs should provide the rst clue as to the origin of any operational
failure. If these are o, it usually means that the ber is broken or has too much attenuation.
Next, be certain that the input and output signal connections are correct.
An optical power meter, such as the FiberLink 6650, a visible light source, such as the
FiberLink 6656, and a Three Wavelength Light Source, such as the FiberLink 6652, can
greatly assist and expedite troubleshooting of ber optic transmission systems and are
recommended tools all installers should have available.
Finally, although multimode and single mode devices may look the same, they will not
operate properly together. Using the wrong device or ber can easily add more attenuation
than specied, resulting in poor overall performance. It should be noted that some of our
ber optic products support both single mode and multimode ber in the same unit.
If, after reviewing the above possibilities, the system is still not operating, please contact
the Customer Service Department for further assistance. If you suspect your problem is
caused by the optics or the ber optic cable, and you have an optical power meter, please
take the appropriate measurements prior to contacting support.

electrical connections are secure and accurate. Please see the Troubleshooting section of
this manual for additional information.
An optical power meter, such as the FiberLink 6650, a visible light source, such as the
FiberLink 6656, and a Three Wavelength Light Source, such as the FiberLink 6652, can
greatly assist and expedite troubleshooting of ber optic transmission systems and are
recommended tools all installers should have available.
All other questions or comments should be directed to our Customer Service Department.
It should be noted that many “problems” can easily be solved by a simple telephone call.
If you suspect your problem is caused by the optics or the ber optic cable, and you have
