FOM-3901 and FOM-3902

The FOM-3901 and FOM-3902 both provide complete electrical isolation for Nortel’s Meridian™ M2000 and M3000 series digital telephones. The FOM- 3901 connects to the digital line card and automatically senses and corrects any improper polarity reversals on the RJ-11. The bidirectional signaling between the digital line card and telephone is then carried across a duplex fiber optic cable. The FOM-3902 reproduces the digital signaling at the isolated end of the fiber optic link and provides power sufficient to operate M2000 and M3000 series digital telephones. The FOM-3902 also provides +42VDC power to auxiliary relays in the M2016S telephone. FOM-3901 & FOM-3902
