LM2100 |
2 Channel Video Mux with 1 Return Audio or Data Channel |
|
| DESCRIPTION
The 2100i is a reliable, cost effective,
state-of-the-art, one fiber video and data
or audio transmission system. The 2100i
is frequency Modulated/Frequency Division
Multiplexed (FM/FDM) for superior performance.
This system is designed to eliminate cross
talk on adjacent channels. This fiber optic
system transmits two channels of real-time
video and one data or audio return channel
over one fiber. Multimode or singlemode
versions are available. The 2100i accepts
PAL, SECAM, and NTSC formats. B&W or
Color signals are seamlessly transmitted
distances of up to 6Km (multimode) and 80
km (singlemode). The 2100i capabilities
are enhanced by it's compatibility with
Lascomm's PC based SpectraSmart™,
Network Management and Remote Diagnostic
Software System. SpectraSmart™ supervises
the operating parameters of the transmission
system such as status on video levels, sync,
FM carrier detect, voltage, temperature,
optical levels, etc., and external equipment
which are attached to the Lascomm equipment.
See the SpectraSmart™ brochure for
more details.
