Alarm Output Specifications:
The alarm output is driven by a normally closed MOSFET. It should be pulled to an external voltage (50V max) through
a resistor. The MOSFET has a typical “on” resistance of 330 ohms. The external resistor should be chosen such that the
maximum current is less than 25mA.
The alarm output is at high impedance when the unit is functioning properly, and at low impedance when there is no
power or no optical signal is present at the receiver, or the SFP is missing.
