8-Channel Digitally-Encoded Video Multiplexer
Transmitter and Receiver
COMPAK81M1
8HARDENEDINCLUDED
The ComNet™ FVT81M1 and FVR81M1 multiplexers simultaneously transmit eight
channels of video over one optical fiber utilizing state-of-the-art digital encoding and
decoding for high-quality 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.
FEATURES
› Digitally-encoded video transmission, transmits
8 real-time color video signals on one optical fiber
› Exceptionally low video distortion with zero Performance
Variation vs. Optical Path Loss
› Compatible with all NTSC, PAL, or SECAM CCTV camera
systems
› Wide optical dynamic range: optical attenuators are never
required
› NTCIP compatible
› Designed to meet full compliance with the environmental
requirements (ambient operating temperature, mechanical
shock, vibration, humidity with condensation, high-line/lowline voltage conditions and transient voltage protection) of
NEMA TS-1/TS-2 and the Caltrans Specification for Traffic
Signal Control Equipment.
› Voltage transient protection on all power and signal input/
output lines provides protection from power surges and
other voltage transient events.
› Robust design ensures extremely high reliability in
unconditioned out-of-plant environments
› Bi-color (Red/Green) LED status indicators provide rapid
indication of critical operating parameters
› Hot-swappable rack modules
› Interchangeable between stand-alone or rack mount use –
ComFit
› May be DIN-rail mounted with the ComNet model DINBKT4
adaptor (sold separately)
› Lifetime Warranty
APPLICATIONS
› High-Performance CCTV (Fixed Video)
