2.3.1 DB25 Control & Sequence
2.3.1.1 Output Power Control
PIN1~8 controls the output laser power by TTL signal. The encoding can be set within the
range of 0~255 which is corresponding to the 0~100% output power. The actual output laser
power may not be a linear relationship with these settings. And the actual output power also
related to the frequency (see Figure 4). Please refer to the example in table 9 current setting:
