Function
MOD_MON
V_CC
V_CC3
Modulation Current Monitor. Connect directly through a resistor to GND (MON_POL
high) or to V_CC3 (MON_POL low). The current through this pin is approximately 1/
100th of the MODULATION current to the laser.
This pin may be left open if the feature is not needed and the M02061 current
consumption will be reduced by 0.5mA typically.

V_CC
V_CC3
Bias Current Monitor. Connect directly through a resistor to GND (MON_POL high) or
to V_CC3 (MON_POL low). The current through this pin is approximately 1/100th of the
BIAS current to the laser.
This pin may be left open if the feature is not needed and the M02061 current
consumption will be reduced by 0.5mA typically.
Transmit Power Monitor. Connect directly through a resistor to GND (MON_POL high)
or to V_CC3 (MON_POL low). The current through this pin is approximately the same as
the photo diode current into IPIN.
This pin may be left open if the feature is not needed and the M02061 current
consumption will be reduced by the IPIN current.
