Method And Apparatus For Monitoring The Rf Drive Circuit Of A Linear Laser Transmitter

US Patent:
5809049, Sep 15, 1998
Filed:
Dec 19, 1996
Appl. No.:
8/770100
Inventors:
Mark Steven Schaefer - Salem NH
David B. Winick - Bedford MA
Assignee:
Lucent Technologies Inc. - Murray Hill NJ
International Classification:
H01S 300
US Classification:
372 38
Abstract:
The present invention monitors the RF drive circuitry of a linear laser transmitter. In one preferred embodiment of the present invention, a filtered RF signal from the monitor diode is amplified and then input to a peak detector. The output of the peak detector is then fed to the input of a threshold detector, wherein the threshold detector determines whether the output of the peak detector is above a predetermined threshold. If the output of the peak detector falls below the predetermined threshold an alarm is generated at the status monitoring ports of the laser transmitter.
