The American Fibertek MRT860C is a video transmitter component of the 860 series which transmits six channels of high-quality video on one multimode optical fiber. Designed to be completely transparent to all camera and monitor manufacturers. This system requires no field adjustments at installation or additional maintenance thereafter. Diagnostic indicators provide a quick visual indication of system status. In addition, two sub-carriers can be added to each video channel using the 500 Series modulators and demodulators. Equipment may be mounted as stand alone modules or rack units by the position of the mounting brackets.
