Notes: 1. PIN 17 and 18 provide an analog voltage output proportional to the laser bias current, based on the following

formula: Ibias = V (Bmon+ - Bmon-) / 10 Ω. See below the equivalent circuit.

2. PIN 19 and 20 provide an analog voltage output proportional to the monitor photodiode current, based on the

following formula: Imon = V (Pmon+ - Pon-) / 200Ω. See below the equivalent circuit.

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

above. The received power is given by the photocurrent multiplied by the photodiode responsivity.
