LM9000 |
High Resolution RGB Video System |
|
| DESCRIPTION
LM9000 fiber optic high-resolution system
is designed to transmit RGB signals up to
1200 X1600 resolution via optical fibers.
This system uses three independent fibers
for each color and it can be installed as
a standalone module or a rack mount card.
The units operate with Sync on green or
with Sync on all three colors. These systems
are capable up to a maximum of 128 KHz of
horizontal frequency 120 KHz of refresh
rate. The Link budget on the multimode system
is 10 dB. The reliable, low cost implementation,
long distance transmission LM9000 is a state
of the art alternative to coaxial systems.
The 9000'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
LM9000 RGB transmitters are installed in rack
mountable 14 slot subracks with dual redundant
or 18 slot subracks with single power supplies
at computer source. Three fibers connect transmitters
to receivers which plug into the desk chassis
at the remote monitor location. LM9000 require
no user adjustments as a result of superior AGC
and dynamic range circuit design. Supports 50
and 62.5/125u fibers.
