The series 160 is a frequency modulated (FM) state-of-the-art fiber optic video system that transmits and receives a real time video signal plus high fidelity audio or data signals over one multimode or singlemode fiber. PAL, SECAM or NTSC formats, in B&W or color, are seamlessly transmitted distances of up to 6Km (multimode) and 100 Km (singlemode). Available formats are balanced/unbalanced audio, GenLock, Manchester, Biphase, RS- 232D, RS-422A, 4-20mA current Loop, TTL, and contact closure. The capabilities of the Model 160 are enhanced by it’s compatibility with Meridian’s PC based SpectraSmartTM network management and diagnostic software system. SpectraSmartTM 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 Meridian equipment.
