FiberLink 4160 & 4320 Series
Welcome
The FiberLink 4160 & 4320 series optical transmission system are a congurable, adjust-
ment-free transmitter/receiver pair that employs digital processing and transmission
techniques to convey up to 16 or 32 one-way channels of audio.
The use of digital encoding assures high-quality noise-free transmissions that retain all of
their initial parameters regardless of ber optic cable attenuation. In addition, integral LED
indicators are provided on each unit to continuously signify the presence of audio signals
and, thus, the proper operation of each side of the system. .

Installation Instructions
The Fiberlink 4160/4320 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 dierent 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 conguring 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.
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.
Installation Instructions
The transmitting element in the FiberLink 4160/4320 trans-
mitter unit contains a solid state Laser Diode located in the
optical connector. This device emits invisible infrared elec-
tromagnetic 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!

Audio Switch Settings
The audio interface circuit used in this product has external switches that are used to
congure the signal options. If you wish to make changes to the factory default settings,
please refer that the charts below:
Balanced/Unbalanced Audio
The transmitter and receiver units each have a set of switches that allow the user to specify
whether audio input/output should be balanced or unbalanced for each channel. Each
end is congured separately. For example, channel 12 may be congured to have balanced
input on the transmitter unit and unbalanced output on the receiver unit.
The chart below indicates how to use the“BAL/UNBAL” set of switches. One switch corre-
sponds to each channel available in the series.
High Impedance/24k Ohm Termination
The transmitter unit has a second set of switches that allows the user to select between a
high impedance >24 k Ohm input termination or a 600 Ohm input termination. This set is
labeled “TERM HI-Z/600.” One switch corresponds to each channel available in the series.

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.
