Installation Instructions
The Fiberlink 4040 Series transmission systems are normally preset for immediate use
with audio input circuitry set for balanced 600 Ohm input impedance and output set for
balanced audio. If a dierent protocol is desired, it can be easily selected using the ip
switches located on the back panel of the unit. (See Page 7.) There are indicator LEDs on
the units for monitoring purposes and several user selectable options for conguring audio
inputs and outputs. The following instructions describe the typical installation procedure
and the function of the LED indicators.
The following instructions describe the typical installation procedure:
1) The various options, as already mentioned, have been preset. If unbalanced high-input
impedance or unbalanced output is desired, please refer to instructions on page 7.
2. Connect the ber optic cable between the two Fiberlink units.
3. Apply power to both units. Refer to Figure 1 for DC power connections.
4. When power is applied, the green POWER LED will light, indicating the presence of
operating power.
5. Connect the audio input signals to the proper positions on the removable terminal
blocks. (See Page 8) Be certain to check all connections and assure that inputs and
outputs are not intermixed.
6. The green audio LED indicators (one per channel) will give an indication as stated on
page 9. Note that the rack card version also has a red LED for indicating the presence
of an alarm condition.
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® 4040 transmitter
unit contains a solid state Laser Diode located in the optical
connector. This device emits invisible infrared electromag-
netic 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 sucient intensity to cause
instantaneous damage to the retina of the eye. Direct
viewing of this radiation should be avoided at all times!

Operating Pointers
Remember to check attenuation of the ber optic cable. The system will only operate
properly if these specications 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 specied, 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.
