BIASMAX
Maximum Bias Current Set. A resistor connected from this pin to ground sets the maximum bias
current. The bias current cannot exceed this level. The APC loop controls the bias current up to the
level of the BIASMAX. For APC open-loop operation, this pin sets the laser bias current.

APCSET
Average Power Control Set. A resistor connected from this pin to ground sets the desired average
optical power. Connect a 50k
