GENERAL DESCRIPTION
The ADN2841 uses a unique control algorithm to control both
average power and extinction ratio of the laser diode (LD) after
initial factory set up. External component count and PCB area are
low as both power and extinction ratio control are fully integrated.
Programmable alarms are provided for laser fail (end of life) and
laser degrade (impending fail).
The ADN2841 has circuitry for a second monitor photodiode
which enables DWDM wavelength control.
