The American Fibertek 946C-SL Series transmits four channels of high­quality 10 bit digitized video and one cha nnel of multi- protocol data (RS 485 (2
wire or 4 wire) or RS422 or RS232 or Manchester) and a bi-directional
contact closure on one singlemode optical fiber at 1310 and 1550nm.

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 that are
mounted in the American Fibertek Card Cages: SR-20/2 or SR-20H/2 ( with
redundant power supplies).
