PRODUCT SPECIFICATION
4-CHANNEL DIGITALLY ENCODED VIDEO MULTIPLEXER
VT/VR7400 SERIES
FEATURES
• High-Performance CCTV (Fixed Video)
APPLICATION EXAMPLES
DESCRIPTION
The IFS VT/VR7400 series multiplexers simultaneously transmits
four channels of video over one optical fiber utilizing 8-bit digital
encoding for the high-quality video transmission. 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 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 available in either standalone or rack mount configurations.

* Optical transmission distance is limited to optical loss of the fiber and any additional loss introduced by connectors, splices and patch panels. Distance can also be limited by
fiber bandwidth. ** For 50/125 Fiber, subtract 4 dB from Optical Power Budget.

This product may be used with 62.5µm graded index multimode fiber having a maximum
run length of 2 km and/or a maximum optical loss of 10 dB.
(1) When ordered with the Fiber Optic Auto Reversing Switch FOARSMM (-R3), the optical power will be factory adjusted to maintain a net optical power budget of 10 dB.
NOTE: All optical terminations need to be epoxy polished with a minimum back reflection of -30dB.
***VT7450-HP requires a minimum of 3dB loss to operate.
