Notes:
1.
Pins 19 and 20 provide an analog voltage output proportional to the monitor photodiode current,
per the following formula: IBIAS = .V(Pmon+ - Pmon-) / 200Ω. The figure below shows the
equivalent circuit.
2.
Pins 17 and 18 provide an analog voltage output proportional to the laser bias current, per the
following formula: IBIAS = .V(Bmon+ - Bmon-) / 10Ω. The figure below shows the equivalent
circuit.
