The American Fibertek 188 Series transmits high-quality, simultaneous FM
video and stereo audio on one multimode optical fiber. These systems are an
excellent choice for demanding audio/video distribution or distance learning
applications. Designed to be completely transparent, these systems require
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.
