SETUP AND OPTICAL POWER ADJUSTMENT PROCEDURE Setup
Introduce individual current sourses for DFB and SOA with common cathode. Spacer anode pin shoud be left open
for normal operation. If required, introduce the other current sourse for heater pin. Thermistor pins can be used fortemperature monitoring of the module.
 Optical power adjustment
With measuring optical power,(1) Adjust DFB (and Heater) current so that the optical power becomes the maximum.
(2) Adjust SOA current to obtain the required power within the maximum rating.
(3) If needed, repeat the procedure of (1) to (2).
