MODEL LM4600

4 Channel Video Mux with 2 Duplex Audio or Data Channels

DESCRIPTION

The 4600i is a reliable, cost effective, state-of-the-art, one fiber video and data or audio transmission system. The 4600i 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 four channels of real-time video and duplex audio and data or two duplex data, over one fiber. Multimode or singlemode versions are available. The 4600i accepts in PAL, SECAM, and NTSC formats. B&W or Color signals are seamlessly transmitted distances of up to 5Km (multimode) and 80 km (singlemode). The 4600i 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.
