Installation Instructions
The Fiberlink® 3500 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® 6650, 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) Connect the video output cable to video output BNC connectors on
the receiver unit.
3) Terminate any unused BNC output connector at 75 Ohms.
4) Connect the ber optic cable to the transmitter and receiver units.
5) Connect the Universal Power Supply to the transmitter and receiver units.
For box versions using DC power, please refer to gure 1.
6) When power is applied, the green POWER LED should illuminate, indicating the
presence of operating power. The 3G/HD/SD RATE LED will give an indication as
described in the Indicator LED’s and Alarm Circuitry section of this manual.
7) 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® 3500 transmitter unit
contains a solid state Laser Diode located in the optical connec-
tor. This device emits invisible infrared electromagnetic radiation
which can be harmful to human eyes. The radiation from this opti-
cal 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 view-
ing 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.
Note: If no signal is applied to the 3500 Transmitter, no optical power will be present on the
3500 Transmitter’s output.
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! There-
fore, 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 whenever optical
connectors are exposed to air. It is also a good idea to gently clean the tip of an optical con-
nector 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 Fiber-
link® 6656, and a Dual Wavelength Light Source, such as the Fiberlink® 6652 for Multimode
or 6654 for Single Mode, can greatly assist and expedite troubleshooting of ber optic trans-
mission systems and are recommended tools all installers should have available.
Finally, although multimode and single mode devices may look the same, they will not oper-
ate 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 customer service.

Maintenance and Repairs
The Fiberlink® 3500 Series has been manufactured using the latest semiconductor devices
and techniques that electronic technology has to oer. They have been designed for long,
reliable and trouble-free service and are not normally eld repairable.
Should diculty 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 optical
connectors are free of dust or dirt that could interfere with light transmission and that
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 Dual Wavelength Light Source, such as the Fiberlink® 6652 for
Multimode or 6654 for Single Mode, 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
an optical power meter, please take the appropriate measurements prior to contacting
customer service.

Fiberlink® 6656 Visible Light Source
The Fiberlink® Visible Light Source provides a visible 650
nm laser output that can be used for identifying ber
breaks and individual bers within ber bundles, allow-
ing for convenient, on-site testing of ber networks dur-
ing construction and maintenance procedures.
Fiberlink® 6650 Optical Power Meter
The Fiberlink® Optical Power Meter measures the power
of optical signals at 850, 980, 1310 and 1550nm wave-
lengths, allowing for convenient, on-site testing of ber
networks during construction and maintenance proce-
dures. It can be used to measure the power of an optical
signal reaching the receiving end of a ber optic cable,
as generated either by a transmitter unit or by a light
source such as the 6652 or 6654.
Fiberlink® 6652 and 6654 Dual Wavelenth
Light Source
The Fiberlink® Dual Wavelength Light Sources oer a
laser output at wavelengths of 1310 and 1550 nm (6654)
for single mode ber and 850 nm and 1300nm (6652)
for multimode ber. Both models allow for convenient,
on-site testing of ber networks during construction
and maintenance procedures.

The Fiberlink® 3360 Series allows you to transmit 3G, HD or SD-SDI as per SMPTE
424M-2006, 292 and 259 with the ability to embed up to 8 channels (4 pairs) of
AES/EBU digital audio. Convenient switches on the 3360 Series transmitter allow
the operator to embed each of the four pairs of audio independently, to strip
previously serialized audio, or to pass it through without modication. At the
receive end of the ber optic link, the operator can decide which audio pairs they
need de-embedded.
Audio signals are not required to operate the Fiberlink® 3360 link and it can be
used as a stand-alone 3G/HD/SD-SDI optical link. Previously serialized data is left
intact throughout the entire transmission process and the 3360 Series is immune to
pathological signals over the entire budget link and operating temperature range.
Signals are equalized and re-clocked prior to ber optic transmission and the 3361
receiver features a re-clocked SDI output.
The 3360 Series is compliant with SMPTE 297-2006 and has the ability to operate
seamlessly with Fiberlink® Matrix and other SMPTE 297-2006 ber optic compliant
devices.
Available in card versions and a small footprint box version, it is ideal for broad-
cast or corporate studios, OB vans, rental and staging, auditoriums, stadiums and
theaters, airport or transportation hubs, distance learning, surgical or medical
imaging and more
