| MODEL
LM100 |
1 Channel IM Video System |
|
| DESCRIPTION
The LM100 is a Intensity Modulated (IM)
state-of-the-art fiber optic video system
that transmits and receives real time video
signals over one multimode fiber. PAL, SECAM
or NTSC formats, in B&W or color, are
seamlessly transmitted distances of up to
8Km. The LM100 is compatible with the LM130
triple transmitter and receiver cards for
high-density applications. This product
requires no user adjustments & features
superior quality and performance. The 100'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.,
as well as external equipment which are
attached to the Lascomm equipment. See the
SpectraSmart™ brochure for more details.
