Notes:

1. Pins 19 and 20 provide an analog voltage output proportional to the monitor photodiode current,

per the following formula: I BIAS = .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: I BIAS = .V(Bmon+ - Bmon-) / 10Ω. The figure below shows the equivalent circuit.

3. Pin 1 is used to monitor the received photocurrent. It must be connected to a positive voltage

within the range specified above. The current that flows into this pin is the received photocurrent. The received power is given by the photocurrent multiplied by the photodiode responsivity.
