DESCRIPTION
This module in the SV
product family incorporates an all-digital encoding
technology that transmits four real-time, simplex 8-bit
video channel in one direction over one optical fiber. NTSC,
PAL and SECAM video formats are all seamlessly supported.
These single fiber, laser based systems are available in
both, Multimode and Single Mode modules.
CONFIGURATIONS
The SV product family is
available as rack mount cards and modules that can be
installed in any of Lascomm’s desk chassis or in 19” racking
frames. This system can be configured in either star (module
to rack) or trunking (rack to rack) configurations. These
systems can be transformed in to a standalone module by
utilizing an SR-500/S (standard configuration) or an
SR-1000/S.
APPLICATIONS
Intelligent transportation
