The American Fibertek 726C-SL Series transmits two channels of
high-quality 10 bit digitized video, one channel of bi-directional multi­protocol data, and one bi-directional contact closure channel on one
singlemode optical fiber using WDM technology. 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. The “Afinety” intelligent remote

monitoring system is available on this product, please consult
factory.

Equipment may be ordered as stand alone modules or rack cards,
