ABSTRACT:
A Hall effect sensor associated with the receptacle of a laser transmitter module senses the presence of a magnet carried by a fiber-optic connector when the connector is inserted in the receptacle. The output signal from the sensor is used to disable the laser transmitter if the fiber-optic connector is not inserted, providing a safety interlock as well as a positive key against the insertion of incompatible multimode connectors.
