Analog
Laser power monitor. Output proportional to transmit laser average
output power. Nominal value of 0.5 V should remain constant due to
high gain power control loop. Range: 0–2 V, ± 100 A

Laser temperature monitor. Output proportional to transmit laser
temperature V = 0.764*e3887*(1/T - 1/298) Volts, where T is temp in
Kelvins. Nominally 0.4 to 0.6 V under normal operation. Range: 0–3.3

Logic 0: Alarm
Logic 1: Normal
Laser power alarm. Logic high when the laser output power drops to
half of the beginning of life output power, and corresponds to a voltage
of 0.25 V on the Laser Power Monitor (LsPOWMON) analog voltage.
