The American Fibertek 86 Series transmits and receives standard telephone signals on one multimode optical fiber using AM/FSK transmission. This system is designed to be completely transparent to all telephony signals including ring, off-hook, hook-switch flash and forward disconnect. Products require no field adjustments at installation or additional maintenance thereafter. Diagnostic Indicators provide a quick visual indication of system status. The 86 Series are ordered as stand alone modules or rack cards that are mounted in the American Fibertek Card Cages: SR-20D/2, or SR-20R/1.
The MT and RT supports up to 1000 feet of 24 AWG wire from the fiber optic unit to the telephone handset.
Other 86 series product configurations include 2 fiber units at 850 or 1300nm and an MX or RX series “talk down” (order wire) phone system. Contact the factory for details.
