MODEL LM4000

4 Channel Video Mux

DESCRIPTION

The4000i is a reliable, cost effective, state-of-the-art, one fiber single wavelength video transmission system. The 4000i is frequency Modulated/Frequency Division Multiplexed (FM/FDM) for superior performance. Cross talk on adjacent channels is eliminated. This fiber optic system transmits four channels of real-time video over one fiber. The 4000i accepts PAL, SECAM, and NTSC formats. B&W or Color signals are seamlessly transmitted distances of up to 5Km (multimode) and 80 km (singlemode). The 4000i 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.
