Operation
Resetting a Laser Fault
Resetting a laser fault by toggling the Tx_Disable input will permit the SFF-PGG-1063/1250-SW/LW to
attempt to power on the laser following a fault condition. Continuous resetting and re-powering of the laser
under a hard fault condition could cause a series of optical pulses with sufficient energy to violate laser safety
standards.
To alleviate the possibility of violating laser safety standards, the SFF-PGG-1063/1250-SW/LW will turn off
the laser if a second fault is detected within 25ms of the laser powering on. This lock is cleared during each
power on cycle. Please refer to the timing diagrams below.
