DESCRIPTION OF EQUIPMENT
Functional Characteristics
The VersiVision FVT1000/FVR1000 Series products are fiber optic video links designed to
extend a frequency modulation (FM) video signal over a single fiber optic cable. These modems provide
high quality transmission of one channel simplex video at distances to 3km using multimode fiber and
distances to 30km using singlemode fiber. A BNC connector provides the copper interface for the video
input/output. ST and SC optical connectors are standard for the fiber optic interface. The FVT1000 and
FVR1000 modems are completely compatible with the NTSC, PAL, or SECAM video standards.
VERSITRON FVT1000 and FVR1000 Series Fiber Optic Video Modems utilize APC circuitry
while maintaining stable optical power output. The fiber optic link established between the transmitter
and receiver devices insures immunity from EMI, RFI, and ground loops. AD, Pelco, Phillips, and
Vicon communication protocols are supported. The modems’ plug and play design requires no user
adjustments. LED status indicators include video sync present (VIDEO) and power on (POWER).

Physical Characteristics
The VersiVision FVT1000 transmitter and FVR1000 receiver modems are available as standalone
devices for easy plug and play installation. In addition, the FVR1000 receiver modems can be ordered as
circuit card modules (See Chart Above) for installation in the Model FVC14 rack-mount chassis. The
14-slot chassis fits in a standard 19” rack and is offered with either 110VAC or 220VAC power
supplies. The dimensions of the FVT1000 and FVR1000 standalone devices are 7.5in (L) x 6.3in (W) x
1.2in (H).

*Optical transmission distance is limited to optical loss of the fiber and additional loss caused by
connectors, splices, and patch panels.
CAUTION!
The transmitter unit contains a light-emitting diode located in the optical connector. This device emits
invisible infrared electromagnetic radiation that can be harmful to human eyes. The radiation from this
optical connector, if viewed closely without any protection, may cause instantaneous damage to the retina
of the eye. Direct viewing of this LED should be avoided at all times.

INSTALLATION INSTRUCTIONS
INSTALLATION PROCEDURE
The VersiVision FVT1000 Series transmitters and receivers are preset for immediate use. There are indicator
LEDs on the units for monitoring the real-time status of video, and power. The following instructions describe
the typical installation procedure and the function of the LED indicators located on each unit.
1. Connect the video source (camera) to the video input BNC connector on the FVT1000 transmitter unit
using coaxial cable.
2. Connect the video output BNC connector on the FVR1000 receiver unit to the video monitor using
coaxial cable.
3. Connect the fiber optic cable between the transmitter and receiver devices.
4. Apply power to both the transmitter and receiver using the PSACV1 power supplies provided.
Note: If using any of the FVR1000M modules, power is provided from the integral power supply of the
FVC14 chassis.
5. When the power is applied, the red POWER LED will light, indicating the presence of operating power.
The green VIDEO LED will give an indication as stated in the following page.
6. The link should now be operational.

SECTION 3
TROUBLESHOOTING
OPTICAL FIBER
The VersiVision FVT1000 and FVR1000 Series fiber optic video modems are available for applications using
multimode or singlemode optical fibers. Please be certain that the correct size and type of fiber is being used for
the particular mode transmitter/receiver combination.
Also be certain that the attenuation and bandwidth of the fiber optic cable being used is within the range of the
system’s loss budget specifications.
GENERAL
Any dirt or dust may easily pollute or block the fiber from accepting or radiating light. Therefore, please try to
keep the optical connector clear and always use the dust caps whenever the connector is exposed to air. It is
suggested that the tip of the optical connector should be carefully cleaned with a lint-free cloth moistened with
alcohol from time to time.
The status of any of the VIDEO LED should provide the first clue as to the origin of any operational failure. If
the VIDEO LED or the receiver unit is off, it usually means that the fiber is broken or has too much attenuation.
Next, be certain to check all connections and assure that inputs and outputs are not intermixed and transmitter
and receiver are not connected incorrectly.
Note: If the system is still not working after examining the above possibilities, please contact our Customer
Service Department for further assistance.
