The status of the VIDEO and AUDIO indicator LEDs should provide
the first clue as to the origin of an operational failure. If these are off, it
usually means that the fiber is broken or has too much attenuation. Next,
be certain that the input and output signal connections are correct.
Finally, although multimode and single mode devices may look the
same, they will not operate properly together. Using the wrong device
or fiber can easily add more attenuation than specified, resulting in poor
overall performance.
If, after reviewing the above possibilities, the system is still not operating, please contact the Customer Service Department for further assistance.
MAINTENANCE AND REPAIRS
The Pure Digital Fiberlink® 7220 Series transmission units have been
manufactured using the latest semiconductor devices and techniques
that electronic technology has to offer. They have been designed for
long, reliable and trouble-free service and are not normally field repairable. Should difficulty be encountered, Communications Specialties
maintains a complete service facility to render accurate, timely and reliable service of all products.
The only maintenance that can be provided by the user is to ascertain
that the optical connectors are free of dust or dirt that could interfere
with light transmission and that electrical connections are secure and
accurate. DANGER! Always disconnect the transmitter power before
removing the optical fiber from the unit!
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 phone call.

GENERAL INFORMATION
Introduction
The Pure Digital 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 fiber. 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 fiber 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.

RECEIVER (continued):
Audio:
OFF: Indicates no audio detected over fiber and, as a result,
no active audio detected by the receiver unit.
BLINKING: Indicates audio detected over fiber and, as a
result, active audio detected by the receiver unit.
Alarm: ON: Loss of video or optical signal (rack card only).
OPERATING POINTERS AND TROUBLESHOOTING
Optical Fiber:
The 7220 Series is available in versions that operate with most multimode (MM) and single mode (SM) optical fibers. Be certain that the
correct size fiber is being used for the particular transmitter/receiver
combination.
Also, remember to check the attenuation and bandwidth of the fiber
optic cable. The system will only operate properly if these specifications fall within the range of the system’s loss budget.
Miscellaneous:
Operating Temp. Range ........... -20 to +60 degrees C
Operating Power ...................... 9-24 Volts AC or DC@5 watts (max.)
Troubleshooting:
Multimode fiber optic cable contains an optical fiber with a light
carrying “core” that is only .0025 inches (62.5 microns) in diameter.
Single mode fiber 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 fiber from
accepting or radiating light. To prevent this from happening, always
use the provided dust caps whenever 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.

TRANSMITTER:
Video:
OFF: Indicates no video detected on the input.
BLINKING GREEN: Indicates either H or V sync detected at
the input but not both.
STEADY GREEN: Indicates both H and V sync detected on
the input.

*Distance specifications are only approximate and are not

DANGER! The transmitting element in the Pure Digital Fiberlink 7220 transmitter unit contains a solid state Laser Diode located within 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 without a fiber optic cable connected to the optical connector, may
be of sufficient intensity to cause instantaneous damage to the retina of the
eye. Direct viewing of this radiation should be avoided at all times.
