FVT/FVR401
4-CHANNEL DIGITAL VIDEO MULTIPLEXER
10-BIT DIGITAL/SHORT-HAUL
The ComNet™ FVT/FVR401 multiplexer simultaneously transmits four channels of
video over one optical fiber utilizing state-of-the-art 10-bit digital encoding and
decoding for high-quality video transmission that meets the requirements of EIA
RS-250C for short-haul video transmission. These environmentally hardened units
are ideal for use in unconditioned roadside or out-of-plant installations. These units
are completely transparent to and universally compatible with any NTSC, PAL, or
SECAM CCTV camera systems. Plug-and-play design ensures ease of installation and
no electrical or optical adjustments are ever required.
Bi-Color LED indicators are provided to indicate the status of the system, video and
data. See Figure 4 on Page 3 for LED indication explanations.
These units may be directly plugged into the ComNet Rack (Part C1) or they can
operate as standalone modules. See Figure A on Page 4 for mounting instructions.
See Figures 1 – 4 for complete installation details. No additional parts or power
supplies are required.

INSTALLATION CONSIDERATIONS
This fiber-optic link is supplied as a Standalone/Rack module. Units should
be installed in dry locations protected from extremes of temperature and
humidity.
C1-US, C1-EU, C1-AU OR C1-CH CARD CAGE RACKS
CAUTION: Although the units are hot-swappable and may be installed
without turning power off to the rack, ComNet recommends that the
power supply be turned off and that the rack power supply is disconnected
from any power source. Note: Remove electrical connector before
installing in card cage rack.
1. Make sure that the card is oriented right side up, and slide it into the
card guides in the rack until the edge connector at the back of the card
seats in the corresponding slot in the rack’s connector panel. Seating
may require thumb pressure on the top and bottom of the card’s front
panel.
CAUTION: Take care not to press on any of the LEDs.
2. Tighten the two thumb screws on the card until the front panel of the
card is seated against the front of the rack.
WARNING: Unit is to be used with a Listed Class 2 or LPS power supply
IMPORTANT SAFEGUARDS:
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may
be greater than room ambient. Therefore, consideration should be given to
installing the equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such
that the amount of air flow required for safe operation of the equipment is not
compromised.
