VT/VR7800 SERIES

8-CHANNEL DIGITALLY ENCODED VIDEO MULTIPLEXER

FEATURES

• 8-Bit Digitally Encoded Video Transmission
Transmits 8 Real-Time Color Video Signals on One

Optical Fiber

8

DESCRIPTION

The IFS VT/VR7800 Video Transmitter/Multiplexer and Video
Receiver/Demultiplexer series utilize state-of-the-art 8-bit digital
encoding and decoding for high-quality video transmission that
exceeds the requirements of EIA RS-250C for Medium-Haul Video
Transmission. These environmentally hardened units provide trans­mission of eight independent video channels over one multimode or
singlemode optical fiber and 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 system. Plug-and-play design ensures ease of installa­tion and no electrical or optical adjustments are ever required. LED
indicators are provided for rapidly ascertaining equipment operating
status and these units are provided in either a stand alone or a rack­mount configuration.

APPLICATION EXAMPLES

• High-Performance Multiple-Channel CCTV Transmission

• Installations with Limited Fiber

• Conduit with Limited Space for Additional Cabling

• Exceeds All Requirements for RS-250C Medium-Haul
Transmission: Extremely High Video Performance

• Exceptionally Low Video Distortion with Zero
Performance Variation vs. Optical Path Loss

• Tested and Certified by an Independent Testing 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.

• Ideally Suited to Networks Requiring Multiple Physical

Layers Where Video Degradation may be a Problem

• Directly Compatible with All NTSC, PAL,
or SECAM CCTV Camera Systems

• Wide Optical Dynamic Range: Optical Attenuators are
Never Required

• LED Status Indicators Provide Rapid
Indication of Critical Operating Parameters

• Solid-State Current Limiters
on All Power Lines Provide
Unconditional Equipment
Protection

• Comprehensive Lifetime Warranty

• A & E Specifications, (CSI)

• AutoCAD Drawings

• Operation Manuals

• Technical Bulletins
