The American Fibertek 0890 Series transmits two channels of high-quality bi-direction audio/contact closure on one multimode optical fiber. Designed to be completely transparent, this product series will provide superior performance in audio systems where 600 Ohms balanced audio and contact closure are required. This system requires no field adjustments at installation or additional maintenance thereafter. Diagnostic indicators provide a quick visual indication of system status. Equipment may be ordered as stand alone modules or rack cards that are mounted in the American Fibertek Card Cages: SR-20/2 or SR-20R/1.
