DWDM Dual MPD Wavelength Control
GENERAL DESCRIPTION
The ADN2847 uses a unique control algorithm to control both
average power and extinction ratio of the laser diode, LD, after
initial factory setup. 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).
Optional dual MPD current monitoring is designed into the
ADN2847 specifically for DWDM wavelength control.
