| MODEL
LM130 |
3 Channel IM Video System over 3 fibers |
|
| DESCRIPTION
The LM130 is a Intensity Modulated (IM)
fiber optic video system that transmits
and receives three real time video signals
over three multimode fibers. PAL, SECAM
and NTSC formats in B&W or color are
seamlessly transmitted distances of 8Km
(multimode). The 130's capabilities are
enhanced by it's compatibility with Lascomm's
PC based SpectraSmart Network Management
and Diagnostic software system. SpectraSmart™
supervises the operating parameters of the
transmission system such as status on video
levels, sync, voltage, temperature, optical
levels, etc., and external equipment which
are attached to the Lascomm equipment. See
the SpectraSmart™ brochure for more
details. |

CONFIGURATIONS
The LM130 is available as a rack mount card that
can be installed in all of Lascomm's card chassis,
desk chassis and 19" racking frames. The
LM130 can be converted to a module by installing
it in the SR-500 card chassis. This system can
be configured in either star (module to rack)
ortrunking (rack to rack) configurations and can
accommodate up to 54 transmitters or receivers
in a 19" chassis for high density applications.
The LM130 is compatible with LM100, single channel
units. This product requires no user adjustments
and features superior quality and performance.
APPLICATIONS
- Security and Surveillance
- Military Communications
- Intelligent Transportation System (ITS)
