Description
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. Plugand-play design ensures ease of installation and no
electrical or optical adjustments are ever required.
Bi-color (Red/Green) LED indicators are provided for
rapidly ascertaining equipment operating status. These
units are interchangeable between stand-alone or card
mount configurations.
Features
- 10-bit digital video transmission: transmits 4 real-time
color video signals on one optical fiber
- Exceeds all requirements for EIA RS-250C short-haul
transmission: Extremely high video per formance
- Exceptionally low video distortion with zero
Performance Variation vs. Optical Path Loss
- Ideally suited to networks requiring multiple physical
layers where video degradation may be a problem
- Compatible with all NTSC, PAL, or SECAM CCTV
camera systems
- Wide optical dynamic range: optical attenuators are
never required
- NTCIP compatible
- Tested and certified by an independent laboratory for
full compliance with the environmental requirements
(ambient operating temperature, mechanical shock,
vibration, humidity with condensation, high-line/low-line
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 unconditional protection
from power surges and other voltage transient events.
Applications
- High-Performance CCTV (Fixed Video)
LIFETIME WARRANTY WWW.COMNET.NET TECH SUPPORT: 1.888.678.9427
- Robust design ensures extremely high reliabilit y in
unconditioned out-of-plant environments
- Bi-color (Red/Green) LED status indicators provide
rapid indication of critical operating parameters
- Automatic resettable solid-state current limiters
- Lifetime Warrant y
