1
If any of the I/O pins are shorted to GND or V
CC
(single-point failure; see Table 2), and the bias current or the photocurrent
exceeds the programmed threshold.
2
3
End-of-life (EOL) condition of the laser diode. The bias current and/or the photocurrent exceed the programmed threshold.
Laser cathode is grounded and photocurrent exceeds the programming threshold.
4
No feedback for the APC loop (broken interconnection, defective monitor photodiode), and the bias current exceeds the
programmed threshold.
